• Stecker
• Low Voltage
• High Voltage
• APFEL Control

• Light Pulser 1 (Mainz)
• Light Pulser 2 (LED Matrix)
• Chiller???

• go to hadanapc4
• go to /home/DCS/Temperature/
• make sure, vxi11 is an executable. Check with $ ls, name of vxi11 should be green. If not, do $ sudo chmod +x vxi11
• run $ python3 BEAMTIME22_temperature_standalone.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

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.

also on VME PC:

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

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!

also on VME PC:

• cd QDC_v965
• ./qdc_readout

the QDC needs a gate to start measuring something!!
