Change of main power line for MPOD and CLOVER preamp


Because the incident yesterday with the NIM crate,
we try to separate the CLOVER from the rest of 
the equipment.

So we put the MPOD, which powers the CLOVER but also
the 3He tubes and the VETO detectors, and the preamp
power supply in a different line.

We check if this has an impact on the noise in either
CLOVER or 3He tubes.

We measure with the 137Cs-60Co source:
File: 161014_1241_137Cs60Co.root

After inspecting the spectra we conclude that the impact
is not appreciable.

See figures 

662keV resolution:
D4Black: 3.16keV
D4Red: 2.49keV
D4Green: 3.57keV
D4Blue: 3.40keV

Drying of preamplifiers

PA8, PA9 and PA10 are removed and brought to a dryer box
to stay overnight and see if the situation with spurious signals
improves as suggested by Mesytec.
Extra drying in the morning with a hair dryer.

Attached the updated excel file. In the first sheet there is the calculator to calculate the efficiency from an given energy.

The Jackel function used is:
Double_t fun=TMath::Exp((par[0]+par[1]*TMath::Log(x[0])+par[2]*TMath::Log(x[0])*TMath::Log(x[0]))*2/TMath::Pi()*
(TMath::ATan(TMath::Exp(par[3]+par[4]*TMath::Log(x[0])+par[5]*TMath::Log(x[0])*TMath::Log(x[0]))))-25.);

End of the test measurements

... and sashimi (see photo)

The detectors (BRIKEN tubes, CLOVER, VETO detectors, AIDA) 
are mounted, tested and ready for November commissioning,
except beam detectors a Plastic TOF and a Si detector which
will be attached to the PE shielding.
DACQs (BRIKEN, AIDA) are running. The synchronization monitoring
program which was working in June, for some reason is not functioning
properly now and is being worked on (desirable but not required).
The data merger and near-line analysis programs are being worked on.

We started the preparation of 2017 campaign

Electronics and DACQ for July 2016 assembly: hardware and connections

Attached is the present setup including all walls, auxiliary detectors, degraders etc. and the Takechi setup.
The lead wall will be removed for measurements (of course...).
Not to scale! Some sizes and distances included. Pictures see Jose's entry ID 110.

Note the shape of the active area of the DeltaE Silicon detector, see previous entry.

This is the setup which was used for the Ni runs (from Nov. 8th evening on).

Note (Nov. 10th): Alejandro built a U-shaped Pb wall, the degrader inside AIDA was removed and possibly a Al plate was installed. This has to be checked when access is possible again.

High voltage control: All High voltage 3He and HPGe can now be set via a configuration file called hvmon.conf and a program called hvmon. hvmon also watches the temperature of the HPGe via the RTD outputs and sets trip and other safety settings.

The important locations are as follows:

• Path for conf file: /home/pixie16/DAQ_BRIKEN/include/hvmon.conf

• Path for temperature monitor: /home/pixie16/DAQ_BRIKEN/kelvin/kelvin-u3

• Path for temperature logging: /home/pixie16/DAQ_BRIKEN/kelvin/kelvin-log

• Path for temperature log control: /home/pixie16/DAQ_BRIKEN/kelvin/kelvin-read

• Path for hvmon: /home/pixie16/DAQ_BRIKEN/hv-mpod/hvmon

• Path for hvmon control: /home/pixie16/DAQ_BRIKEN/hv-mpod/hvmon-read

This is also the order in which the programs should be run at first.

If the kelvin temperature monitoring programs are already running ('ps -A | grep kelvin' to check) and you wish to change the settings:

1. Adjust hvmon.conf

2. stop 'hvmon' with ctrl+c

3. rerun by './hvmon' (also 'up + Enter')

If kelvin is not running, in a separate window or screen

1. cd /home/pixie16/DAQ_BRIKEN/kelvin/

2. ./kelvin-u3 &

3. ./kelvin-log &

Then proceed with the above.

This is also the order in which the programs should be run at first. 

If the kelvin programs are already running ('ps -A | grep kelvin' to check) and you wish to change the settings:

2 OPTIONS!

Option 1:
Adjust channels that have previously been declared by using

./hvmon-read

16

and follow on screen instructions. If channels have not been declared previously in hvmon.conf → proceed to option 2.

Option 2:

1. Adjust hvmon.conf

2. stop 'hvmon' with ctrl+c or by ‘100’ at hvmon-read

3. rerun by './hvmon &' (also 'up + Enter')

The example below turns on ALL detectors PA (Pre-amps1-10), D4/G7 HPGe (KRGB, Black, Red, Green, Blue), and YSO/Gari. This example sets all detectors voltage,ramp up/down speed and status (0/1 = Off/On respectively). IMPORTANT! Ramp speed goes card by card.

UPDATE!!

3He Preamps now run up and down by a small ramp for the first 50V hardcoded into hvmon via the ‘PA’ keyword. This avoids the reset fault.

=================================================

Everything below type = -1 is treated as a comment

type = 0 => MPOD HV modules => accessed thru snmp

type = 1 => CAEN x527 HV modules => accessed thru CAENHVwrapper

With MPOD one can use IP address and channel numbers based on slot occupation
PA(1-4) are differential and PA(5-10) are unipolar.

In the program hvmon-read ‘Off’ always means ramp down and then turn off. The PA's like to hold on to voltage (~10-50V) and may cause a fault at ramp down and need reset. This should be Fixed with two stage ramping.

Warning!!: It has also been realized that mpod changes ramp up to be equal to ramp down. These parameters can be made equal for transparency.

To reset after fault use:

./hvmon-read

18 (or 5 then 18)

In case of power loss or other failure hit to do an emergency shutdown of the voltages.

./hvmon-read

5
