Abstract

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.

Description Simulations of a high pressure TPC showed that with 5 bar pressure and 0.25 cm2 pitch, such a detector can address nuclear model deficiencies important to the discovery of CP violation.

Operation of the TPC showed this pitch can be achieved.

A successful beam test proposal to CERN won 5 weeks of beam time in late 2018. Analysis of the data is underway.
Exploitation Route The instrument constructed with the funds from this proposal now underpins a UK-led bid for AIDA funding (to be submitted in March 2020).

Description As a result of this work, the DUNE near detector design will utilize HPTPC technology. A beam test at Fermilab of the HPTPC with new readout is being prepared for late 2020.
