Some spectra show spikes or do not look normal. This should be checked.

Look at BRIKEN, Ring4, Ring5, Ring6, Ring7, D4, G7, Clovers, 
Rate1, Rate2, Rate3, etc.

Reset time stamp: 21.00, 8th-nov.

Probably there was a problem with the clock from AIDA related to the LN2 filling.
So to recover, we need to stop acq (only stop acquisition in DACQ control), 
send to hard (send parameters again) and once all the parameters were sent, 
Send Sync pulse.

Measurement with 252Cf at Z=22.5cm from the moderator border, opposite side from AIDA.
Clovers and Veto detectors are turned off.
Beam is off.

Obs: There is a problem in the online data for this run. DAQ for VME1 do not stored data. This problems seems to
be a crash on the DAQ. I restarted the system and run again the measurement. The display for voltages has lost
connection. The channels on VME1 have been checked, no problems is observed in the waveforms.

Again, this time without observing problems:

BRIKEN spectrum is attached for this run. Counts in the pulser are 1.123e4

We put the 252Cf source and check the aligment of 3He tubes gains:

File: 181025_1600_252Cf_gaincheck.root
All OK except 133, 35 and 140

He133: peak at 744keV
He135: peak at 783keV
He140: peak at 739keV

No gain correction  applied at the moment but should be verified
before experiment

- Start DACQ computer: OK!
- Create directory: /data/1810Preparation/
- Copy last configuration RIBF139 file:  171119_1126_Conf_BrikenFullYSO.xlsx
- Return PB-5 pulser into crate and set parameters
- Star all crates: OK!
- Start DACQ: OK!
- Rename configuration file and edit to eliminate YSO related parameters
  New Config file: 181016_Conf_BrikenFull.xlsx
- Start 3He tube HV: power the ethernet hub, power the pixie PC,
  edit the hvmon.conf file (only tubes active), run hvmon: OK!
- We realized that current and voltage of VME crate 1 was oscillating.
  We pulled out V1A7 (not used) and it became stable: seems that we are at the limit of 
  power supply: OK!
- We put the 252Cf source in and check gain match:
  only (the gain of) three tubes moved slightly since the last run (one year ago)!
  He006, He134, He135 -> new calibration: OK!
- We move SIS3820 clock from internal to external frequency:
  Setup UK Tektronix clock: 25MHz, square signal, 800mVpp, -400mV offset
  Plug in Lupo module (VME1 crate): OK!


ISSUE: the current placement of the table supporting the MUSIC chamber
is too close to the VME1 crate and one of the modules (V1A4) 
cannot be extracted in case of failure. However V1A7 is unused
in this run and can be used as replacement.

Comment:
Tube 121 is noisier than the others (see fig).

Issue:
all the channels connected to PA3 and PA4 
have twice the number of counts than the remaining channels (!?).
Actually the pulser counts.

Solution:
This channels are from UPC tubes and are connected to pulser PB-5.
We found that the threshold of external trigger was set to 1V
instead to 1.8V as before and this was producing a double pulse (see photo)
like triggering on the fall and rise of the trigger pulse.
This happen whenever the threshold as below 1.6V.
We do not understand this: the signal has +2.2V and no apparent ripple (!????).
We set threshold to 1.8V and now is OK

Little noise in some tubes:
He039, He053, He121
We tried to improve the noise by moving cables around
but it didnt work. So we leave as it is. 

***** CHECK DATA, CHANGE OF CONFIGURATION WITHOUT RESTARTING GASIFIC70

We have tested possible change of the baseline in the digitizer due to the pulser connection. NO EFFECT has been
found!


Test for detector He086 ORNL:
He086_NoPulser_samples.png  -> Without pulser, baseline around 1000
He086_Pulser_samples.png    -> With pulser, baseline around 1000


Test for detector He001 UPC:
He001_Pulser_samples.png  -> With pulser, baseline around 1200
He001_NoPulser_samples.png  -> Without pulser, baseline around 1200


Test for detector He013 RIKEN:
He013_Pulser_samples.png  -> With pulser, baseline around 850
He013_NoPulser_samples.png  -> Without pulser, baseline around 850

We have noticed that D4 is not in its right position. That explains the different number of counts in the
detectors. 
Probably of the order of 3 cm away from its nominal place.
The position of the other detector should be also checked.

We realized that the time stamp was not reset.

Both clover detectors were moved. They are in a symmetrical position. The end on the clover nose is of the order
of 3-4 mm from the AIDA tunnel.
