TORCH, a novel time of flight detector for LHCb upgrade II
Description | As part of the award, we performed (a) testbeam and calibration studies for the TORCH detector, (b) developed new TORCH reconstruction algorithms, and (c) we ported tracking reconstruction algorithms on Intelligence Processing Units. For (a): initial results are promising, but not yet final For (b): our new algorithm is about 100x faster than the previous one. For (c): IPUs do not lend themselves well for VELO the tracking algorithm under study. |
Exploitation Route | Our industrial partners directly benefit from our calibration system, a copy of which they will use. Future particle physics experiments, in particular the LHCb upgrade II, will benefit from the progress we made on making TORCH a functioning detector, and by speeding up its complex pattern recognition. The community using (and making) IPUs has shown great interest in the use of IPUs outside the classical machine learning paradigm they have been designed for. The disappointing performance we achieved when porting a tracking algorithm to IPUs that works well on GPUs is relevant in that context, even though it is disappointing. |
