Started both RSAs for the tuning of the ESR to 188Hf. Both pockets are in parking position OUTSIDE.

Currently, we only use 37% of the injections in our data analysis. However, 63% of the injections have a height below 100, and these may include 
single ion injections. We need to visually inspect these injections to identify the single ion injections.

The repair of SIS electron cooler power supplies

In the meantime we received a few injections and confirmed that 194Pb setting is still as it was before entering into the ESR

Now we change to 208Pb82+ to do several ESR accelerator tests

Esis = 517 MeV/u
Change the beamline to 208 Pb 82+ and the ESR to 208 b 82+ and NO other changes

We had stopped the RSAs at 8:00 (call for restart)
Time stamp computer stopped and started at 9:35

We are going to enter the ESR to check on the PLEIADES pocket detectors and install a nitrogen cooling.

Spike in beam intensity at 06:27 (5x usual intensity) and then beam is lost. HKR says it's a problem with the magnet's power supply. Once the beam returned, the peaks are shifted to the left but are slowly shifting back into position.

Stable since last entry

The peaks in the analyzer are slowly shifting back to the original position. 
Note that a quadrupole was the cause of the issue 45 mins ago and it was cycled.  Might be relevant...

Beam is back for 10 mins-

The peaks on the analyzer appear shifted to the right.

As I write this the beam disappeared again.... 02.59

and back again at 03.08

HKR has called someone to fix the quadrupole, they think it will take about an hour.

Since around 01:45 we get spills but see nothing on analysers. HKR says there is a problem with one of the quadrupoles; they are working on it.

Beam gone again between 01:14 and 01:18, then again at 01:19. HKR says there are problems with the source.
