CTOF Timing
This section looks at the timing of the CTOF data
CTOF raw timing
Looking at the raw ADC and TDC times of CTOF hits. The raw data is translated using conversion values for ADC and TDC Digi Data.
double ADC2ns = 0.0625; double TDC2ns = 0.0234375;
An example of the CTOF timing for ADC and TDC with looking at CTOF trigger events where the physics trigger did also fire. The data is from run 101604 and run 101606. The distributions for these runs suggest a general base-time offset for ADC and TDC of about 96ns and 285ns, respectively.
ADC timing run 101604 and run 101606
TDC timing run 101604 and run 101606
ADC timing run 101290 and run 101291
TDC timing run 101290 and run 101291
