We changed the dye at 10am.

We increased the pump power for the dye Laser to 480mJ (before 450mJ). New calibration factor is 29 for Quanta Ray monitor signal.

We get now 17mJ UV pulse energy after SHG. Pulse energy before was 14mJ.

The power supply of the UNILAC magnet is broken. The repair will take up to 6-7 hours.

The kicker problem is solved and the beam is back in the ESR.

Questionable 1kHz and delayed common stop signals has been removed.

These two cablings were for some previous tests.

we had no injections in the ESR again 

it turned out that the injection kicker of the ESR has a problem 

GLOBAL calculations for the "content" of the Th line in the Schottky spectrum
(380 MeV/u exit energy, equilibrium charge state distribution)

Actinium 9.9%  - bare 

Thorium 42.4% - H-like

Protactinium 44.8% - He-like

Uranium 2.7% - Li-like 

since shortly after 7 AM we have no beam in the ESR
(reason unclear) 

Both DAQs also crashed. 

Beam back in ESR at 7:20 or so

When the XUV-detector has to shut down unexpectedly, it can happen that the Mesytek power supply crashes and can't be 
communicated with. If this happens the Mesytec PS needs to be restarted from hand inside of the ESR. This can be done by 
restarting the crate located at the bottom of the XUV-detector. 

This crash happened during the night shift today and the Mesytec should be restarted today as soon as possible. For 
example when the laser stabilization gets fixed.

In normal operation this should never happen if no mistakes are made.

Some ToDo's for the next shift:
- Work on  Laser stabilisation 2nd stage in the ESR
- Mesytec power supply of the xuv-detector crashed and needs to be restarted in the ESR. Simply turning it the crate off and on again)!!
- Fix wavemeter fluctuates
- Compare MBS event size of DAQ 1 ("by laser group") and DAQ 2 ("by Carsten"), DAQ 1 data size was ~2 times larger than DAQ 2 data size.
- Use lmd-files measured last night to test Go4-Analysis.
- Practice measurement procedure with beam, see Message ID: 124.

A lot of cables were wrongly or not 
connected to the DAQ 2. 

Channels are now for both DAQ:
0 XUV-Back
1 XUV-Anode
2 XUV-Anode-delayed
3 PMT-South
4 PMT-Middle
5 PMT-North
6 PMT-Cu
7 Part-det-south
8 Part-det-north
9 1kHz
10 -
11 -
12 Delay-common-stop
13 PD-NO
14 PD-SO
15 Q-switch

All data taken by the DAQ2 has to be 
considered as faulty up to now. 

Carsten was furious.
