These numbers represent the delay, in microseconds, between the leading edge of a 120Hz pulse and the leading edge of the trigger pulse sent to the pulse picker spindle in order to "catch" the next pulse.
Timing Measurements
Measured on 2014-07-09 with reflaser and photodiode in XCS, using ioc/common/pulsepicker/R1.0.0
and firmware revision Ns=96.
- Flip-Flop mode: 8.6ms from pulse picker trigger to center open position. Open time is 4.4ms.
- Burst/Follower mode: 6.6ms from pulse picker trigger to first light (open); 4.9ms from pulse picker trigger to last light (close).
...
- Flip-Flop mode:
- 0ns (or minimum TDES) for aggressive timing (very next FEL pulse)
- 8000ns for conservative timing (skip one FEL pulse, capture the one after that)
- Burst/Follower mode:
- 0ns (or minimum TDES) for aggressive timing (very next FEL pulse)
- 5000ns for conservative timing (skip one FEL pulse, capture the one after that)
