1. Create relevant histograms (change of variable MAX_STEP from 10 to 13 and insertion of histogram names "QSWP1MS", "NORTH_GATED" and "MIDDLE_GATED" in the std::string array stepNames.
   Both adaptions were made in TLdaInputDescription.h)
   
   
2. Fill the respective histograms. Changed lines of files TLdaAnlProc.cxx, TLdaAnlProc.h are listed below.
   

We checked all three signals in the Messhütte. Laser scan and laser step are OK.
The Laser busy signal is for large increments (0.1nm) also fine. For short increments like our usual 0.005nm increment the signal is irregularly.
Likely the laser busy status is too short.

To accumulate more data into the opened go4, do not restart MBS, but just

sto ac
clo fi
open file lxg1297:/data.local2/208Bi/208Bi -auto -rfio
sta ac

Note: This does not work, because go4 somehow accumulates ~5 extra laser steps when starting a new scan which results in an x-axis-offset between the runs.

In run 8134 - 8135 PMT North showed a super high background rate. After the scan we checked the signal cables.

Incoming signal was still good until CFD. We changed channel from 2 to 12. New threshold is 36, was 10.

During the last run, PMT North showed some weird noise.

The PMT was replaced by the deep UV PMT with small aceptance range (100-200nm) but there was still a lot of noise on the output channel in the Messhütte, see attached photo. The intensity of the noise signal was as strong as a normal signal count.

I replaced all cables and used other preamplifier channels. The noise is gone and the baseline is flat now. However, the timing of PMT north will be a bit different now, so we should use PMT middle for the laser/ion overlap as we did before.

Graziano opened the valves for the laser and turned off the vacuum gauges and emergency lights. The background of the UV PMT looks normal (Middle 10 Hz, North 1 Hz) so I think we are fine here.

Timing for the final measurements on 209Bi was determined for the new frequency 1.93777MHz. Peak positions are

PD NO 106
PD SO 141.5
PMT MIDDLE 45 (due to the broad temporal structure difficult to determine)

Center between PDs is 123.75. Difference to PMT MIDDLE is 78.75. This is ~3 bins larger than the half period of 75. 

We recorded files with high wavemeter readout rate and saved it at the atplaser network drive (Q:) - Bismuth - wavemeter folder.

Could be used to calibrate the laser steps. The MBS readout rate is 4 Hz, here 30 Hz, so there are a few more values.

After a phone call with Wilfried I implemented an offset to all hit channels of the stacked / accumulated spectra where one chekcs the timing peaks.

Therfore, I made a copy of the analysis in 208Bi1 (one "1" at the end). And here, in the file TLdaAnlProc.cxx I added an offset of +70 to the hit channel (variable UInt_t hit, around line 335 /336 of the code).
Pleasse note that I just inlcuded one line with a "magic" number here, since I cannnot test teh compiling and was afraid to introduce an error.

So the lines were

UInt_t hit =tdcSE[i][j];

changed to 

UInt_t hit =tdcSE[i][j];
hit = hit + 70;

Plesaede note that you need to recompile and check and set all conditions for the time-preak window.

So , you now use the analysis in 208Bi1

It is necessary to start go4 before you start the laser scan. Otherwise you get an offset in the laser Step plots.

The main control room started setting up the Bi beam this morning, but quickly stopped in order to solve some problems around the UNILAC. Therefore we 
should not plan to receive ions earlier than late in the evening on Monday, or probably Tuesday during the day.

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.
