1. 8/4~8/9 Work H.Y.Huang

2. 8/4 Improve VB program to resolve that the counter recording numbers turn to we want

3. 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

4. 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

5. 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

6. 8/5 2.The singals are unstable Solve ： Using original singals to create another Gate,then using the gate to create

7. 8/6 Solving minimum 0.2us 1.Using two original singals,one is standard, another using to delay singal original singal → → delay singal

8. 8/6 Data Start→Stoptime(us) singals→singals(ms) events real event 1 10 1524 6000 0.8 10 1550 6000 0.5 10 1549 6000 0.2 10 1539 6000 0.1 10 1570 6000 0.08 10 1591 6000 0.06 10 1590 6000 0.04 10 1595 6000 0.03 10 1608 6000

9. 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

10. 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
