[edit] Singles Scan Setup for a TIGRESS detector
Before commencing the singles scan, the detector needs to be mounted and the scanning table needs to be calibrated so that (0,0) is at the centre of the detector. Calibration instructions are here.
[edit] Procedures
- Using a browser, go to http://midtig03.triumf.ca:8081, and select tigscan
- In a terminal run mhttpd -p 8081 -D (runs daemon)
Run mserver
ssh lxdaq03 (password as usual)
cd /home/tigscan/Collector
./fetigcol - In a terminal tab,
cd /home/tigscan/Packages, cd jacq_midas, cd V1.0,
./feMotor (Start motor) - In a terminal tab,
cd /home/tigscan/analyser
Check if another analyser is running on tigaccept. Do this by typing odb, then selecting the tigaccept experiment, then typing scl. If you see an analyser, it may already be running on port 9090 ( the default). Exit this application. To check if you have the right port do ./analyzer -s 9090
If it crashes, try ./analyzer -s 9091
Whichever port works is the one that you will need for the roody step - In a terminal tab,
mlogger -e tigscan (turns on logger) - In a terminal tab,
roody.
In roody, right click online, enter midtig03:(port number from 4) - in ODB -->/Experiment/Run Parameters/Comment
Add comment for the run - In Roody -->right click and select draw for the following groups:
Core
Segment Blue+Green
Segments Red+White - In ODB-->/Equipment/Trigger/settings/master
Global Multiplicity Mask= 0xFFE
Disabled Port Mask= 0xFC3F
Required Port Mask= 0x0
/GE
Hit Threshold =1250
Trigger Threshold= 1250 - In ODB-->/Equipment/Trigger/common
Event Limit=1500 - In Roody, for each window--> right click--> X-axis range--> (1-3000)
- In case spikes occur @ 170-180 keV,
- ODB--> Programs-->Stop fetigcol
- in terminal in part 2. run ./fetigcol
- check spectra again
- For a save directory:in ODB-->/Logger/Data Dir= “/data1/tigscan/det13/singles+date”
- TO START
in ODB--> /Equipment/motors/settings/XY grid
Start Position [0],[1]=-58; Incriment [0],[1]= 2; steps [0],[1] =58;
Run at acquire=y; Start=y.
