Wed May 19 13:47:26 2021, Jan Glorius, General, GasTarget Operation, 2021 
|
We have two tasks to take over for the target operation:
1. We have to refill the blue LN2 bottle on the roof of ESR every morning (see 1st attached foto)
For this we use the small silver dewar on the floor there. In case this dewar is empty we have to refill it in the yard.
No need to stop the measurement for this.
2. We have to monitor the LN2-level warning on Ulis web page: http://ulpc24.gsi.de/mediawiki/index.php
In case there is a warning (~12h remaining), we have to refill the big dewar at the target in ESR.
This means we need ESR on TSG with the gate open.
In case the nozzle is clogging and we do not reach reasonable densities anymore and E1 pressure is going down, we have to heat up the nozzle manually.
This can be done at the control panel on the roof of ESR (see 2nd attached foto).
The proceedure is:
1. push "set point"
2. type new value in Kelvin (e.g. 100K for start of heating)
3. press "enter" to apply or "escape" to correct typo
4. monitor E1 pressure (should go up)

/u/litv-exp/unpacker/unpackexps/e127_TO_2021_with_ECL
It is also aliased for litv-exp user as: E127_unpack
This is for the data structure as documented here:
https://elog.gsi.de/esr/E127/346

|
We now have a drasi DAQ running for our (p,g) experiments.
The RIO we have it installed right now is: r4l-58
It shall be used with the user <litv-exp>
The DAQ-controle shall be done from lxg1275 inside a SCREEN SESSION named "daq"
tab 0 >> drasi
tab 1 >> logger
tab 2 >> rate
tab 3 >> stream server
tab 4 >> file writing (optional)
To check and control running daq:
login on lxg1275
> ssh litv-exp@lxg1275
enter screen session
> screen -x daq
DRASI
go to tab 0
> ctrl-a 0
should be quite, no errors showing, no terminal outputs
full restart proceedure
> ssh r4l-58
> cd esrdaq_2018/r4l-58
> ./start.sh (for det. triggered daq)
> ./pulser.sh (for internal pulser trigger)
> ctrl-c (for killing daq)
LOGGER
go to tab 1
> ctrl-a 1
should be quite, no errors showing, no terminal outputs
full restart proceedure
> ssh r4l-58
> cd esrdaq_2018/r4l-58
> ./logger.sh
RATE MONITOR
go to tab 2
> ctrl-a 2
rates should update each second
"incr" should be event rate per sec
"send" column should be reasonable value if data is written
full restart proceedure
> ssh r4l-58
> cd esrdaq_2018/r4l-58
> ./rate.sh
EMPTY STREAM SERVER
go to tab 3

empty stream should be running
number of processed events should keep increasing
you should see the number of clients connected

Fri Apr 5 06:05:55 2019, Jan, DAQ, making changes to the DAQ ,
|
If you need to add or change a module of the VME crate you need to follow this proceedure:
1. stop DRASI
2. add/change module in esrdaq_2018/r4l-58/main.cfg
a. add module name and VME address: CAEN_V830 (0x00A00000) {}
b. use BARRIER keyword between the modules
3. restart DRASI (e.g. ./pulser.sh)
4. check empty unpacker data output
> empty --stream=r4l-58 --print --data
should run without error and now have your new module event data
5. adjust unpacker in ~/e127/unpackexps/esr
a. make sure you have a .spec file defining readout of you module, e.g. "vme_caen_v775.spec"
b. edit main_user_esr.spec
- add module as e.g. "tdc[0] = VME_CAEN_V775(geom=0x2, crate=0);"
- select "geom=0x1" value according to ascending order of all modules (0x1, 0x2, 0x3, ...)
c. edit det_mapping.hh
- add SIGNAL() keyword for your module
- e.g.: SIGNAL( TDC_1, esr.tdc[0].data[0],TDC_32, esr.tdc[0].data[31], DATA12);
- choose data format, e.g. "DATA12", as specified in module .spec-file
d. compile your unpacker:
> make -j
e. try it out:
> ./esr --stream=r4l-58 --print --data
- should run without errors
> ./esr --stream=r4l-58 --ntuple=RAW,/dir/file.root
- root-file should have your new branches with your module data |

This is the first position calibration done with the detector installed in the holder. The goal is to assign rough positions (top/bottom/left/right) to PreAmp- and Shaper-channels.

PreAmp Channel | polarity | position
| |
1-1 (Y-1) | neg. | bottom
| |
1-16 (Y-16) | neg. | top
| |
2-1 (X-1) | pos. | left (close to beam)

2-16 (X-16) | pos. | right (far from beam)
