Minutes BHCal Meeting 2025-09-12, compiled by Anjaly and Stefan
General
• Stefan is editing the preTDR
• Oleg: date for the page turn and review might slip a little bit
• Ravi Koka (Sevil Salur’s Rutgers group) wants to join the hardware efforts (Apply for DOE fellowship to be at BNL)
• Stefan showed the neutron fluence plots as a function of distance, from Fredi. (Macro and plots attached to the indico agenda) Questions raised by Murad and Oleg:
• Width of beam gas interactions (plot should be more smeared out)
• Plan to invite John Haggerty and Fredi to meeting next week
PROTOTYPE STATUS AND PLANS
Anjaly:
• Martin and Anjaly moved trigger setup from Hcal lab to high bay. (Moved the previous NIM crate, HV PS, function generator, HGCROC board and the two scintillator paddles)
• Tested reading out 16 tiles from the prototype.
• But, timing (or something else) seems to be not right—this will be revisited next week.
Olaiya
• Plots of the cosmics phase scan data taken in hcal lab in May. (Cable length of 400 cm)
• Double peaks appearing due to an issue in code?
• Olaiya wrote his own code; needs direct comparison with what Norbert had.
Problem with neutron simulation still there (one point looks wrong)
