Scope Trace @ No Beam CH1 : B, AvTech LD pulse input CH2 : A, SMD trigger CH3 : Scintillating fiber CH4 : To, Master trigger

Shot 1, Only Triggering, No Detector Responded

Shot 2

Shot 3

Shot 4 ~ 0.004 ms

Shot 5 ~ - 0.001 ms ~ ± 3V level

CONFIRMATION NEAR FIELD DETECTOR DOES WORK. ALL SYSTEM RESPONDED TO THE 5 TIMES OF BEAM RUNNING SUCCESSFULLY. WHAT DOES SIGNAL LEVEL MEAN ?? HOW TO CALIBRATE THE AMOUNT ?? TRIGGERING SIGNAL TO OPTICS ARRIVES ~0.001 MS LATER THAN THE BEAM ARRIVAL.  THE MINIMUM REQUIRED DELAY OF TRIGGERING SIGNAL FROM PS IS ~ 0.006 MS INCLUDING ELECTRONICS DELAY ASSUMING SMD CAMERA STARTS CAPTURING THE FIRST FRAME FROM THE TIME THAT BEAM ARRIVES. ALL OTPICS AND CAMERAS DOES WORK SIMULTANEOUSLY ONCE THE TRIGGERING SIGNAL ARRIVES FROM PS.
