As Hisham put the timing signals of the scintillators on high resoltuion spectrometer, I went for a new round of HV on/off data taking. Unfortunately I am not seeing any signal beyond pedestals in the scintallators (and yes Ic heck the HV were on). I'll get Alex's help later on today.
Here is what I did this morning: DAQ config: leftHRS, ps5=7 all other at max values. run 6342: S2M L partially off, chanel 0,3,4,5,6,7 & 8 off run 6343: s1 partially off, chanel 0,3,4,5,6,7 & 8 off run 6344: s2M R partially off, chanel 0,3,4,5,6,7 & 8 off run 6345: cerenkov partially off, chanel 2,4,6 and 8 off
