Speakers: Alexandru Bercuci (IFIN-HH), Claudiu Schiaua (IFIN-HH/DFH)

Beam-time campaign

1. warm-up phase                                                  Tue 18.06  09:00  - Tue 18.06  18:00
2. low-rate, detector performance tests              Tue 18.06  18:00  - Wed 19.06 9:00   
3. rate-scan, detector performance tests           Wed 19.06  9:00  - Wed 19.06 16:00  
4. high rate, detector performance tests              Wed 19.06  16:00  - Fri 21.06    6:00  (also high rates measurements 25 kHz/cm2 in ToF) 

Test and Calibration activities

1. Pulser runs - testare FW
2. 55Fe si 90Sr
3. CR

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.
