The NTCap DAQ computer in the HKR (Schottky logbook) is started, and all preparations for data taking (mounting of NAS etc.) are done.
Parameters for NTCAP DAQ will be adjusted as soon as beam is available. 

The ESR pattern is enhanced compared to the thorium experiment by additional machines that can be  used for cooling/waiting in order to optimize 208Bi yield.
As a consequence, the sub chain numbers (previous: virtuelle Beschleuniger) are changed. The new numbers still have to be dialed in into the devices in the Messhütte and the automatic in/out of the XUV-detector tested-

The main control room is setting up the SIS for extraction. At the moment there are 2.5E8 particles in the SIS. Later they will check the transport and the devices for the 
ESR injection. The ESR operators might (! no info available) take over later in the evening, but there will definitely be no beam for the experiment before tomorrow morning.

=> the night shift will not take place, unless some laser adjustments need to be done (so far we see no problems)
=> the morning shift does not need to come at 6AM. My guess is that before the morning briefing at 8:30 there will be no news.

The ESR cave is closed again. Talk to the main control room if you need access.

Status SIS on Monday evening. ESR setting up starting on Tuesday morning. There is some prospect of getting more ions by setting up multi-multiturn 
injection, however still uncertain.

There is still no Beam in the ESR.

The beam is currently at TE3 - between SIS and ESR

The lower limit (to position) of the Cobra control VI has to be one increment smaller.
This means for moving from 601,95 to 601,74 the "to position" has to be 601.735.

We also checked the displayed HV values in Go4 with the shown values of the HV VI.

Both values in go4 and in the VI show the same value and are changing "simultaneously" (depending on the refresh time of go4 and Labview).

It is now possible to stabilize and move the laser with both stages.

The software and hardware settings are attached.
For synchronizing with the laser pulse we use following frequency generator settings:
period: 200us
high: 5V
low: 0V
duty: 50% 

The frequency generator is triggered with the external Q-switch trigger signal, that is in coincidence with the ESR HF.
To use the stabilization one has to use the external and NOT the q-switch mode of the laser. 

Since we have ions in the ring now, we looked at the PMT thresholds and the widths. In order to do so we looked at the Raw Signal directly before the CFD and its output simultaneously. You can now set the threshold just above the noise. If the threshold is too low you will also see flat lines in the oscilloscope when triggered on the CFD output. New values:

PMT Mitte
---
Width: 200 -> 220 (60ns -> 90ns)
Threshold: 20 -> 5

PMT Nord
---
Width: 200 -> 220 (60ns -> 90ns)
Threshold: 12 -> 10

PMT Süd
---
blind.

The T-Scrapers at the electron cooler have an issue. They can't be moved in the horizontal direction using the DeviceControl.

Attached are the MSCF shaper settings applied on Tue May 10 at 22:30.

new shift started.
