The system timing adjustment

Usually we sent the SYNC OUT signal from SDG II to trigger the Prometheus, it would induce about several hundreds nanoseconds delay time. Today I changed this signal from SYNC OUT to TRIG OUT. Finally I could match the seed beam with the Prometheus ASE.

Timing setup:

SDGII: OUT1=188ns, OUT2=368ns, SYNC OUT=204ns

DG535: A=T+1.60us (Rail Gap), B=A-1.54us (M02), C=B+30ns (M01), D=A-1.31us (X-ray Anode).
