Current Tasks
Taken data on thick carbon target and same rate.
- Fit it away! - Probably want a thick carbon target to do this study. - May be able to get a different target with similar rates (~1.5% carbon too thin)
Dataset from Dave Mack analysis (fall 2018)
- Different rates same fan speed, etc. to clean this up. - Get kinematics
Using gold on pion running because no carbon.. Misscommunication with Dave M. Need good communication.
deadtime of FADC250 is same as 100ns gate width problem with cherenkov noisy tube.
John comment next run: Triggers - electron trigger ,ps 3/4 and ps (or variable) electron trigger Dave - Typical (Only one trigger type at a time) Make easier do both (3/4 and el-real separate)
- Take pion trigger and take PS pions.
EX) EL-REAL and then take 3/4 vitoed by el-real If want unbiased take electron + ps + ps_factor (Accomplished now by Brad adjusting timing of triggers such that EL-REAL always comes first. That way triggers can be aligned.
EDTM - a real trigger vs pseudo.
Quotes from Burcu in X>1 meeting:
Diagnostic histos • Histos aimed at pi, e, etc… • Diagnostics for EDT, pion prescaling!!!, EDTM prescaling!!!, etc… • Extra scalars and auto-analysis, e.g. of pi/e • Boiling - thin and thick carbon (low rates - BCM offset, high rates - rate dependence). Relatively low pi/e? NEED THICK CARBON!!!! Modest xsec • “pion” trigger as 3/4 VETOED by “real” trigger (if fixed real trigger?) —> exclusive, lower rate (easier to ‘prescale’). EL + PION*PS —> all. [but if you also take prescaled 3/4 (total particles), then it may(?) get complicated again. [100 Hz EDT trigger :white_frowning_face: ] - useful as pedestal, I guess] • Need high-p optics sled, elastic scan, sieve. [dp recon AND angle, so need sieve AND elastic] • 2018 - one trigger type at a time [EDT trigger generates fake “real” triggers] • 2021: ? Some separate 3/4 runs PLUS some prescaled? • [right now: adjust timing to make elreal come first]
