Temperature Readout

ssh to hadanapc5
go to /DCS/Temperature/
make sure, vxi11 is an executable. Check with $ ls, name of vxi11 should be green. If not, run $ sudo chmod +x vxi11
run $ python3 main.py
in the script, you can adjust the TIMEOUT = 120, which is the waiting time between measurement cycles and IP = “192.168.10.14”, which is the ip address of the Keysight module
the last measurement is always print out in the console.
the data for the different protos are saved in seperate files in a directory named after a unix timestamp
the time stamp is the standard unix one
you can also read the temperature of the sensors without logging with $ python3 single_readout.py

Scintillator

High Voltage

start server on VME PC:

got to VME-PC $ ssh 192. 168.10.11
$ cd ~/GEM_Proto/HV/WebHV/
$ ./SYMBhv -c HVconfig_CFD.conf

open a new terminal and start the GUI on hadanapc5:

$ cd ~/VME/HV_CAEN/build-HVgui
$ ./HVgui

Now the GUI window opens. Channel 2 and 3 are currently used for the scintillators. Set the trip current to 30 muA and set the max Voltage to 1500 V. Turn up the voltage to 1300 V, now you should be able to see signals.

CFD

also on VME PC:

$ cd ~/CFD
$ ./cfd_control
the CFD contrl reads the thresholds from the config.txt

Scaler

start Scaler on VME PC:

$ cd ~/Scaler_1000mus/src
$ ./scaler <number of channels> <Dwell time [s]>
the rate for the channels is written in ~/Scaler_1000mus/output/rate.txt. This file is rewritten every time, so this is not meant for storing the data!
