Event-of-the-Day

Fri 23 May 2003

Photo of the event-of-the-day for Fri 23 May, 2003.

Today's event of the day is a data event with a "PC overlap" window that contains two decay positrons and a muon. Above is a photo of the event, where the green clusters are a first muon, and the blue clusters are a second muon, and two decay positrons. The second muon is about 175 ns before the two almost simultaneous decay positrons, so can almost be separated, but I have set the PC overlap time to be about 200 ns.

The event classification for today's data event 31364 of run 11754 is:
 EventType:   5  (PC Overlap)
 Windows:   5
  window  1, T0= -10000., DC window= -10000.     15., hits PC,DC=   0   2 Min,MaxZ=   -9.8   -9.8, type=   5 (Empty)
  window  2, T0=     65., DC window=     15.   1565., hits PC,DC=   6  26 Min,MaxZ=  -59.8   -0.2, type=   1 (Muon)
  window  3, T0=   1565., DC window=   1565.   2565., hits PC,DC=   0   0 Min,MaxZ=   99.0  -99.0, type=   5 (Empty)
  window  4, T0=   2615., DC window=   2565.   4115., hits PC,DC=  24  85 Min,MaxZ=  -59.8   59.8, type=  11 (Muon and Fast Decay Downstream)
