Data taking with fast-extracted U beam T=0.9AGeV (charge state 73+, 17.15 Tm rigidity), June 20, 2024 (C Sturm from MM):
- 3.3s cycle time (sync to UNILAC, acceleration, cooling, extraction)
- approx. 1us extraction duration
- first run #3192, common start: 14:50 CEST, common stop 15:01 CEST, duration 00:11h (short run for fast offline data analysis)
- last run #3199, common start: 20:53 CEST, common stop 22:00 CEST, duration 01:07 h
- all runs taken with 2.5mm Au target
- all runs taken with tag: 2024/production/june_write_pub_all_dets_much6_hdd
- constant and stable beam conditions
- beam intensity ? Might be 100 U ions per 1us extraction within a 3.3s cycle. But this is not measured since particle counters of the present beam diagnostics cannot cope with fast-extracted beams.
