Proton Calorimetry/Experimental Runs/2022

Groningen FLASH Measurements

FLASH range QA measurements at PARTREC UMCG in Groningen.

Using same scintillator stacks from Manchester.

Manchester FLASH Measurements

FLASH range QA measurements at The Christie.

Also measure WET of stack using PTW PeakFinder.

UCLH 1st September 2022

Experimental measurements at UCLH. Fourth beam test with photodiode DAQ system.

Measurements of the WET of stack of white painted sheets and clear sheets (with Mylar) from previous UCLH beam test using IBA Giraffe.

Scintillator light quenching using single scintillator block and camera.

UCLH 16th June 2022

Experimental measurements at UCLH. Third beam test with photodiode DAQ system.

Test light output with Rev. B prototype containing white sheets and clear sheets, comparing with CMOS sensor. Test new Rev.C prototype.

Also contains details on follow-up crosstalk measurements of the two prototypes.

LED Optical Isolation Tests

Lab tests at UCL using LED fibre injection and unpainted sheets with layers of material in between to provide optical isolation.

Test cross-talk and light levels with no material, white paper, black card and mylar foil
