Shift Summary 2/4/2000 Evening: Beam at start: 7.97 mA; Beam at end: 5.97 mA ---> 0 ; Typical Lumin. 1.0 x 10^31 Data type: chi2 background (Ecm = 3535) Runs 5115 (132 nb-1), 5117(77.8 nb-1) Shifters: DB, WR, DJ Log Book 6 Pages 231-234 Summary: Data taking at Ecm = 3535 MeV started around 5 pm, after deceleration and cooling of the beam. At 19:25 the straw chambers' low voltage was found off, therefore there are no straw data for the first 2/3 of run 5115. CCAL channel R10-W45 is very inefficient (from hit map in online monitor). HV for this channel has been checked and is OK. At 20:35 we noticed that the jet target density and the H2 flow rate were dropping: we stopped the run, followed the procedure for unclogging the jet target nozzled and resumed data taking after approximately 55 minutes. Run 5117 stopped at 23:40, when the total luminosity for this point reached 210 nb-1. After a short access requested by the Luminosity Monitor we will go into stacking again. Diego, Willy and David
