Minutes for UCL Proton Calorimetry Meeting, 15th February 2017 (D17, Physics & Astronomy, UCL)

Present

Ruben Saakyan, Anastasia Basharina-Freshville, Laurent Kelleter, Adam Knoetze, Matthieu Hentz

MH:

Worked on emittance of protons in Clatterbridge beam line. Need to check size of initial source (beam outside beam pipe!). Maybe switch so coloured plot instead of scatter-plot. Check for secondary protons, too.

AK:

Made measurements with lower LED frequency. Part of the rate problem is understood: Coming from the frequency dependent signal inverter used for pulser trigger mode. Go to self trigger mode or adapt signal form (NIM to TTL).

LK:
