8/4~8/9 Work H.Y.Huang

8/4 Improve VB program to resolve that the counter recording numbers turn to we want

8/5 Create signals to probe the Timer/Counter resolution ： 1.Using Gate/Delay Generator 2.Singal width = 20ns 3.Start→Stop time ： 1us~0.2us 4.One series singal to next series singal ： 1ms 5.Timer/Counter recyclel ： 0.01s

8/5 Create signals method ： 1.Trigger1 → 2 ； Trigger2 → 1 2.Prolong between two series singals time ： Using original singals to create singals,then coincidence and original singals

8/5 Some Trouble 1.The Gate/Delay Generator minmum is 0.1us,two generator create singals,so minimum between two singals time is 0.2us

8/5 2.The singals are unstable Solve ： Using original singals to create another Gate,then using the gate to create

8/6 Solving minimum 0.2us 1.Using two original singals,one is standard, another using to delay singal original singal → → delay singal

8/6 Data Start→Stoptime(us) singals→singals(ms) events real event

8/7 Using Timer/Counter measure total singals ： 1.Time ： 1min 2.Between two singals time ： 0.2us 3.Counts ： 60/(0.2*10^-6)=3*10^8 No recycle ： 3.3*10^8 0.01s recycle ： 4.7*10^7 Predict losing ： 3*10^6

8/9 4th muon lifetime experiment take counts Time ： 63 hours Singal width ： 20ns 5th muon lifetime experiment take counts Time ： 13 hours Singal width ： 10ns

8/9 63hr Unit ： 0.5us

8/9 63hr Unit ： 0.5us Cancel < 0.5us

8/9 13hr Unit ： 0.5us

8/9 13hr Unit ： 1.0us
