We are continuing taking more DR runes in the morning shift at I_el = 300mA:

opened new file

Time File PTB 32 PTB 33 Ohmlabs ESR intensity SC8 Typical SIS injections comments
8:07 63 205826 205827 205820 0 1.5e9 at about 8:30 the beam was destroyed by a scraper, failure in SIS18 at 8:40 (RF cavity)
9:40 64 205826 205827 205820 1e6 1.3e9 opened new file, at about 9:17 the SIS provided beam again, all looks good
10:14 64 205826 205827 205820 7e5 1.3e9 Voltages have not been read out as the read-out is not active
10:47 64 - - - 5e5 1.3e9 same with the voltages as above
11:24 64 - - - 4e5 1.3e9 same with the voltages as above, SIS cavity (same as earlier today) had problems and about a third of the injections did not come. For us the beam in the ESR was intense enough for a measurement though. ESR intensity after scraping decreases in the last few measurements but before scraping it is roughly the same.
11:58 64 205821 205828 205821 5e5 1.5e9 voltages read from Grafana interface
12:32 64 205821 205828 205821 5e5 1.5e9 voltages read from Grafana interface. Closed file after measurement and halted measurement to maybe get more beam into ESR.
