Table 5.3: Overview of all muon runs taken until November 2010. The name of eachrun also indicates the starting date of the run. The first number is the day in the year,followed by the local time (in CET and CEST accordingly). The number of eventsis determined by a basic cut on the number of hits. For each 2D plane, a minimumnumber of four (three) hits has to be reached, it may not exceed twelve hits.Run Duration [s] Delay [5 ns] U th [mV] n trigger n events,4 n events,3028 12-22-30 686846 100 50 32630 23 41036 11-10-29 5675937 100 50 155660 272 392102 11-08-06 628001 100 50 15911 31 46118 15-04-24 173764 100 50 3913 9 13120 21-15-25 3358291 200 100 70620 182 263173 12-31-34 166847 200 100 2726 3 4175 12-24-38 948399 200 100 15615 28 51187 14-05-39 1072826 200 100 12932 36 53200 04-54-28 191376 200 100 2399 9 14203 18-49-43 838198 200 100 8881 29 39214 01-03-07 2542185 200 100 32474 49 98243 11-23-20 517972 200 100 11215 102 111253 14-44-50 278867 200 100 6505 15 22Sum 17079509 371481 788 1647xyα0: 3.235318, α1: 0.566728, θ: 0.571627, ϕ: 1.424140nhit0: 4/4, nhit1: 4/4Event: 1287, Entry: 208, Time: Sat Jun 26 11:57:12 2010Figure 5.10: Event display of a muon tracked by the CMT on top of Borexino.
