'''WP5 meeting with the Project Office''' ''02 September 2021'' TP – discussion with Carsten Welch (CaW ) 1. Instrumentation in beam pipe – non intercepting unless beam moves off track. Gives you the beam info but does not measure what goes into the cells. 1. Gas profiler – 10 yrs work non-invasive, measurements with small e beam – can get 2d profile of beam as it passes detector. Minimal beam perturbation. Requirement is for pulse to pulse intensity only – remainder of beam system selects for energy and species, so only require intensity. Much of diagnostics for LhARA could be tested at Birmingham without vertical beamline. • Short pulses and small sizes requires money CaW happy to contribute from Cockroft but will need ‘leader’ to support students – 2PDRA for 2 years between Cockroft + BHam. Gas profiler – test, use with scaled down beam and then specify system for final implementation. Assume profiles are Ok – 2 x 1D profiles. 2D profile needs TP silicon system – @ £0.5M.
