We plan to measure:

1. Lifetime of H-like 206Pb81+ beam with two electron cooler currents:
a) 200 mA
b) 10 mA (so that recombination rate is less)
using MWPC (capture detector in outer pocket) and CsISiPHOS (loss detector in inner pocket). 

2. To find the efficiency of the MWPC.

cheers!

The beam is coming from SIS but doesn't arrive in ESR because the quadrupole magnets in ESR have failed.

Update (18:01): Problem has been resolved. 

The gas jet target is now being changed from H2 to Ar by Nikos.

In this high contrast Schottky recording, the main three frequency peaks are resolved w.r.t. time from left to right:

203 Hg 80 +, 200 Hg 79+ and 205 Tl 81+

There are also some spurs visible, whose nature is not 100% sure. One possible explanation can be:

Since this is taken during the storage time (gas target still off), we have no separation between parent and daughter ions, the daughter 205 Pb 81+ basically has the same revolution frequency as parent. It is a possibility that after the decay, daughter ions are slowly cooled back to the nominal frequency. Daughter ions are highly charged and have a high velocity, so single ion sensitivity is expected. They come from all directions, but Schottky measures only the longitudinal plane. Symmetric spurs can hence be an indication of this.

The HKR crew informs us that several machines in ESR are showing malfunctions.
The on-call expert cannot be reached.

Update (16:36): On-call service has been informed.

Update (16:48): ESR cycle stopped.

Alex and Pierre-Michel applied 1500 V to the anode and adjusted the threshold in Messhute.
x1 signal was small & noisy and rest of the signals were fine.

Alex goes to Messhute to check the signals from MPWC. After he completes, we start with the measurements with the primary beam )
