E/dE - ADC Calibration - Low energy protons

Progress:

1.) What kind of events are noise events in DL.T3 histogram?
2.) I changed the cuts to accept also particles that penetrate only into the dE-plane.
3.) In future BigBite code will have to be changed to accept these events properly
4.) Only paddle #0 sees low energy events....

T3-noise events?

Results from last week:

1.)

Noise events in T3 are random coincidence protons and deuterons:

1.)

2.)

4.)

5.)

dE-only events

6.)

7.)

8.)

New results together with dE-only events

TDC - Calibration

Progress:

1.) Need to understand, how triggers/re-timing works.
2.) Found some errors, need to correct them.
3.) Can align all TDCs into a line
4.) To find true coincidence times now I need pathlength corrections
5.) ...
