Minutes for UCL Proton Calorimetry Meeting, 8th March 2017 (D17, Physics & Astronomy, UCL)
Present
Simon Jolly, Ruben Saakyan, Anastasia Basharina-Freshville, Laurent Kelleter, Adam Knoetze, Matthieu Hentz, Andreas Christou, Jordan Silverman
AC:
- Working on waveform fitting in ROOT:
- Gaussian part of the fit works.
- Trying to fit falling edge of pulse using single exponential.
- Will try implementing double exponential.
- Can already filter out pulses with more than one peak:
- Will reconstruct ADC spectrum from filtered waveforms.
- Will vary integration window for pulse (50, 100, 150ns used in experiment).
MH:
- Looking at emittance and beam profile evolution along Clatterbridge beamline.
- Ignoring protons that fall outside the measurement region in simulations.
- Need to check initial parameters and beam density distributions: will plot intensity distributions to make it clearer.
- Updated geometry based on information from Andrzej's.
AK:
- Looking at Hamamatsu PMT response to LED.
- RS and ABF will walk through results to suggest improvements.
