Header: First run with irises open. 30 min run. Ender: Call from PS-Booster. Stop run. Date: 8 Nov 2017 Start: 21:46 Stop: 22:18 Target #2: Position 127.95 mm; CH2_16: 450~480 ug/cm^2. 59Cu beam is on. Nominal intensity was 6 x 10^5 pps. 5.0 MeV/u. Iris are all open. Biases (leak currents did not change opening the irises) dE: -33 V; 0.00 uA E: -350 V; 1.99 uA HI: -14 V; 0.86 uA Pulsers are in. Positive: 2 Hz, 1.4 V. Negative: Low freq, 1200 setting. Scalars 0 and 1 (see https://elog.ph.ed.ac.uk/ISOLDE/49 ) were in at the beginning of the run. Scalar 2 was added part way through. LEMO cables were not long enough to add 3 & 4 until after the run was stopped (swapped short cables for longer ones elsewhere.) Scalar 0 was showing a number of multiple hits. It was directly from the Fan In / Fan Out. At the end of the run, I switched it to the Lecroy 622 which has a larger width. We stopped because the PS-Booster called about cleaning one of the rings. (At first I misunderstood exactly what was going on or who called, but I stopped.) Encoding: HTML ELCode plain Suppress Email notification
