Main points:
 
−
 
−
#TDC settings, comon start, common stop mode.
 
−
# TDC range.
 
−
#changing the TDC settings. and source of TDC hits. (logic fold and dual timer and the effect of the delay)
 
−
# The difference in time scale between the oold and the new TDC settings (scintillator time)
 
−
#write a program for direct analysis of neutron spectrum based on TDC and QDC, and TDC and Peak sensing ADC.
 
−
#The best best GEM operating voltage as the beam is ON.
 
−
#difference between the TDC histograms in the two ntuple root files.
