Beam: 208Pb(82+), 269.0 MeV/u, ~2*10^7 ions in ESR

Position pocket outside: GE01DD2AG (A= aussen, outside)
Position -126mm outside (very left), beam at ~-15mm

- BGO runs
electron cooler current: 20 mA (at ~2:00 am) (SC06): Moved pocket to -20mm
run005-033 with traces on. runs034-037 no traces rate is 1.2kHz
At ~2:35am (run038) changed e current to 100 mA, rate increase to 3kHz.: 
run038-080(?) no traces. run080-117 incl traces

- GAGG runs ~6*10^6 ions
Pocket at -20 mm, e current at 100 mA
Moved pocket to -50mm, 200 mA e current
run0114 - run0143 incl. traces
run0149 - run0157 no traces -> moving detector in/out
run0158 - run01?? cooler voltage changed from 100mA to 200mA

- large CsI
~2*10^7 particles in ring
100 mA e current
run0167 - run0197 incl. traces. Moved detector position from -70mm to -20mm in steps of 10mm
run0??? - run0210 no traces. Status detector pocket.
