Abstract

Neutrons are one of the fundamental particles of an atom with no charge. Because of their unique ability to reach nuclei, neutrons provide unique and valuable insights to many aspects of the physics of matter beyond the capability of any charged particle or ionizing radiation probes. We are now seeing the world at the very limits of our existing neutron probes - the key limitation being the temporal resolution. The possibility of ultrafast (significantly faster than a millionth of a second) studies using neutrons, either as a pump or a probe, has not yet been considered because no high flux sources of such short neutron pulses exist.

Thanks to the continuing developments in laser technology and related areas, access to ultra-intense laser pulses (well above 10^15 watts of pulsed power focussed down to a spot of a fraction of the diameter of human hair) has opened several new avenues of research in plasma physics. One of them is the bourgeoning field of ion acceleration driven by the intense laser light pressure (also called radiation pressure (RP)). Depending on laser and target parameters, the interaction produces either moderate kinetic energy (corresponding to a speed of 1000 Km/sec) and near solid density jets of high Mach numbers, or mono-energetic and collimated ion pulses of ultra-high energy (orders of magnitude higher than the jet ions). The proposal is aimed to develop, test and apply a novel laser based neutron source, exploiting the unique combination of parameters at the frontier of RP driven ion bunches, Since the source is driven by the ions accelerated by a highly efficient laser driven ion acceleration mechanism, it lays a foundation towards next generation neutron facility in light of the rapid development in laser technology. The source with enhanced characteristics will enable expansion of our understanding of ultrafast molecular dynamics in a wide range of discipline, from physics to biology. A laser driven source may bring further advantages in terms of cost reduction and compactness, reduction of radioactive pollution and ability of radiation confinement by closed-coupled irradiation experiments, which will make the source more appealing for industrial, technological and medical applications, such as cancer therapy centre based on a novel, highly promising technique employing neutrons.

Planned Impact

The output of the proposed research will have impact and relevance at several levels and over different timescales. Some of the impact is associated with the training aspect of the activity, others are expected to rise directly from the applied research which will be carried out during the research programme.

Training two Ph.D. students in an exciting multidisciplinary field of research is one of the immediate impact on society that the project is programmed to make. The training will provide them the necessary skills to develop their career pathways in future. During their degree they will make efficient use of national laser facility and may continue to provide scientific supports to the facility in future by joining the team, promoting UK science. The proposed research will also complement the breadth of activities of the host organisation and will facilitate recruitment prospects, particularly with respect to attracting Ph.D. students from outside Northern Ireland and overseas.

Two objectives of the proposed research, such as, characterising a novel radiography technique to greatly improve security measures for large cargos and developing a source for a novel cancer therapy centre, will have direct impact on the society in a long term. Further impact on society can be envisioned through the potential of the proposed method in setting milestones for next-generation neutron facilities, creating new opportunities for training and recruiting scientists, creating new laboratory facilities. This can be seen as a critical pathway to social and economic impact as it lays the basis of continuous supply of well-trained and qualified personnel with a range of options for career in academia, R&D, industry and other sectors, such as finance.

The proposed research will have an important role to play in facing present energy challenges by providing valuable information in answer to two of the most fundamental physics questions related to fusion energy power plants, the most promising source for our bright future.
The proposed work on neutron source development and underlying ion acceleration mechanism has a clear strategic importance to science, in light of the high power and high repetition laser developments. If successful, the project will stretch the realm of ultrafast research for a wider scientific community and will benefit directly our society by improving security measures. It may also open up opportunities for the development of university scale table-top neutron probes and, possibly, novel cancer therapy centres based on the Boron neutron capture technique. Industry may gain from the development of an alternative source for applications such as fuel cell and Li battery diagnosis, semiconductor doping etc.

Description Laser driven neutron sources are currently one of the most attractive areas of research within the community. The main goal of the current project to develop and demonstrate an appealing neutron source for its applications in various areas. There has been mainly three key finding from this project. Firstly, using energetic light ions driven by intense lasers, we were able to demonstrate, for the first time, highly beamed neutron emission from light ion nuclear reactions. Such a beamed neutron flux is highly suitable for further transport and moderation. Secondly, a high flux beam of fast neutrons was obtained from ultra-thin foils, which is a novel way of producing neutrons using high power lasers. In this case, the neutrons are produced by the bulk ions, which are accelerated by mechanism predicted to be the most efficient with the upcoming intense lasers. Finally, we were able to produce high flux of slow neutrons for the first time using a compact moderator, a step towards demonstrating the feasibility of using laser driven sources for the range of applications currently pursued only at giant conventional machines.

In addition to these key findings, there has been a significant effort devoted towards diagnostic development and characterization, which is crucial for the experimental activities related to neutron source development. So far, the funding helped producing 50 peer-reviewed publications, including several papers in high impact factor journals. Several more high impact publications are expected from the work carried out during the project. The project also supported the principal investigator to establish the field of research in UK, by forging new collaboration with people within and outside the laser plasma community, disseminating the outcomes to wider scientific community in international conferences.
Exploitation Route There are several avenues of the research that can be explored further by developing understanding of the underlying mechanisms. Furthermore, further development and optimisation of the moderators for laser driven neutron sources would have a strategic importance towards developing next generation of neutron facilities, a cost effective and compact alternative to the current generation of large-scale spallation neuron facilities. The end application of the research to the end users can be realized in a longer term, with the development of higher power, higher repetition rate lasers. However, in the short term, it is anticipated that the research would make an socio-economic impact by creating new opportunities for training 'fresh blood' and recruiting scientists.

Description The predicted strategic advantages of a laser based technology over conventional methods may be realised on a long (>10 years) time scale, and the proposed research is perhaps at a too early stage of development to provide an accurate assessment of its effective impact in any application areas. However, the project supported to develop a field of research in the UK and motivated to explore avenues of direct societal impact. For instance, funding was secured from STFC, in collaboration with university of Bristol and CLF, forged during the project, to investigate the possibility of using laser driven neutrons for non-invasive inspection of nuclear waste barrels stockpiled at Sellafield. In terms of short term impact activities, the project helped in training several PhD students and helped the principal investigator securing a permanent position at the Queen's university Belfast. The potential of the work attracted interests from a major European laser infrastructure ELI-beamlines, Prague, in order to study the feasibility of developing the first laser-driven neutron beamline for potential users. This would have a significant socio-economic impact via knowledge transfer, secondments and recruitment.

Title Calibration of neutron Time of Flight scintillator detector 
Description Calibration of three scintillators (EJ232Q, BC422Q, and EJ410) in a time-of-flight arrangement using a laser drive-neutron source is presented. The three plastic scintillator detectors were calibrated with gamma insensitive bubble detector spectrometers, which were absolutely calibrated over a wide range of neutron energies ranging from sub-MeV to 20 MeV. A typical set of data obtained simultaneously by the detectors is shown, measuring the neutron spectrum emitted from a petawatt laser irradiated thin foil.

Impact The calibration of this diagnostic enable us to measure the absolute neutron flux and spectrum in our experiments, which has led to several publications about the neutron souces and underpinning mechanisms.

Title Detector for imaging and dosimetry of laser-driven epithermal neutrons by alpha conversion 
Description An epithermal neutron imager based on detecting alpha particles created via boron neutron capture mechanism is discussed. The diagnostic mainly consists of a mm thick Boron Nitride (BN) sheet (as an alpha converter) in contact with a non-borated cellulose nitride film (LR115 type-II) detector. While the BN absorbs the neutrons in the thermal and epithermal ranges, the fast neutrons register insignificantly on the detector due to their low neutron capture and recoil cross-sections. The use of solid-state nuclear track detectors (SSNTD), unlike image plates, microchannel plates and scintillators, provide safeguard from the x-rays, gamma-rays and electrons. The diagnostic was tested on a proof-of-principle basis, in front of a laser driven source of moderated neutrons, which suggests the potential of using this diagnostic (BN+SSNTD) for dosimetry and imaging applications.

Year Produced 2016 
Impact The diagnostic helped to diagnose the spatial profile of moderated neutrons , which is crucial for imaging applications.

Title Differential filtering technique for characterising deutron spectra 
Description A novel method for characterising the full spectrum of deuteron ions emitted by laser driven multispecies ion sources is discussed. The procedure is based on using differential filtering over the detector of a Thompson parabola ion spectrometer, which enables discrimination of deuterium ions from heavier ion species with the same charge-to-mass ratio (such as C6 +, O8 +, etc.). Commonly used Fuji Image plates were used as detectors in the spectrometer, whose absolute response to deuterium ions over a wide range of energies was calibrated by using slotted CR-39 nuclear track detectors. A typical deuterium ion spectrum diagnosed in a recent experimental campaign is presented, which was produced from a thin deuterated plastic foil target irradiated by a high power laser. 
Type Of Technology Detection Devices 
Year Produced 2014 
Impact This technique provides the only way to measure a full deuteron spectra in laser plasma experiments, which is crucial to understand neutron generation. We used this technique in several experiments, which already has led to a number of high impact publications, and more papers are currently under preparation.

Title High resolution Thompson Parabola Spectrometer 
Description A modification to the standard Thomson parabola spectrometer is discussed, which is designed to measure high energy (tens of MeV/nucleon), broad bandwidth spectra of multi-species ions accelerated by intense laser plasma interactions. It is proposed to implement a pair of extended, trapezoidal shaped electric plates, which will not only resolve ion traces at high energies, but will also retain the lower energy part of the spectrum. While a longer (along the axis of the undeflected ion beam direction) electric plate design provides effective charge state separation at the high energy end of the spectrum, the proposed new trapezoidal shape will enable the low energy ions to reach the detector, which would have been clipped or blocked by simply extending the rectangular plates to enhance the electrostatic deflection. After the proof of principle demonstration of the new design in the paper, http://dx.doi.org/10.1063/1.4866021, its experimental validation of an improved version was reported in the paper http://dx.doi.org/10.1063/1.4961028. An further modification of the design in terms of diagnosing angularly resolved ion spectrum in a ultra-compact design was reported in http://dx.doi.org/10.1088/1748-0221/11/10/C10005. 
Type Of Technology Detection Devices 
Year Produced 2014 
Impact The high resolution thompson parabola diagnostic helped significantly to diagnose the ion beams produced from the laser plasma interaction, which is crucial in studying neutron generation. Since its development, the diagnostic has been used in a number of experimental campaigns, by our group and others, continuing to produce high quality results and number of high quality publications.
