How-To-HRS (Detailed documentation and troubleshooting)

A shift portal page is available with summarized instructions for shift takers.

This page contains a listing of all procedures, including information that may be relevant only in specific cases. This page is obviously in progress; please contribute to it or contact any of the tritium students with updates.

How to manage your BTA (for Shift Leader)

Open your browser on an a-onl@aonl machine
[1] https://bta/
[2] Login your name/pass word
[3] File->Open Timesheet
[4] choose: Hall:A -> Day-> Shift: Owl(or Day/Swing)
[5] click "Open"
[6] You see the address bar:
(Note that NO time specifically required! e.g.:https://bta/experimenter/a/2014-12-16/owl/end=2014_12_16_08_00;start2014_12_16_00_00) -> this will give you error when you save info for MCC

Instead, do the following

  https://bta/experimenter/a/2014-12-16/owl/

[7] If you want to edit hour(s), Please click very right "pencil" icon, then make a comment or edit time
DO NOT USE *EDIT ALL* ON THE BOTTOM
[8] To save your edited info into DATABASE, just click "V" (check-mark) in same place of "pencil" icon
[9] When MCC call you for BTA (An hour before your shift end), click "SAVE INFO for MCC"

Troubleshooting

• The start and end of run entries do not show up in HALOG:
  • Make sure you have waited long enough. Automated entries take a while to show up in the HAlog.
  • You want to quit coda, connect to adaql2 as a-onl using ssh, and restart coda. Yes even if you are already connected on adaql2 as a-onl, the ssh part is what you need here.

• If you hear an alarm with a very deep voice, read this [logbook entry.]

Beam Recovery Procedure

Update: October 24, 2010.

• Empty target, establish correct beam position
• 5 uA empty target
• BPM4A (X,Y) = ( 0.0, 0.0) mm
• BPM4B (X,Y) = ( 0.0, 0.0) mm
• See white board for updates on these.
• Tolerances on these : +/- 0.3 mm
• In standard configuration we run without the raster (ok on cryotarget if beam current is less than 5uA)
• Put in BeO target, for visual check of spot (if camera still works)
  • 10 uA rastered beam on BeO.

Data Acquisition

Basic Data Acquisition with CODA (updated 11/3)

This assumes runcontrol is already up. If not, go to Starting CODA From Scratch below.

Need to add a description of what/how the data taking process will occur!

• How to run DAQ on LEFT HRS:
  • From a terminal login as "adaq" on adaq1 machine (do "ssh adaq@adaq1" without the quotes)
  • Password is available on the white board
  • After login to adaq1, type "startcoda" to bring up the runcontrol GUI
  • The default configuration is " ????", if it is not loaded you can choose it from the menu "configurations->Cool", select "????"
  • Click "Platform->connect"
  • Click on "Download" button
  • Click on "Start (>>)" button, and acknowledge "start-of-run" pop-up window
  • To end a run click on "End" button

• How to run DAQ on RIGHT HRS:
  • From a terminal login as "adaq" on adaq2 machine (do "ssh adaq@adaq2" without the quotes)
  • Password is available on the white board
  • After login to adaq2, type "startcoda" to bring up the runcontrol GUI
  • The default configuration is "?????", if it is not loaded you can choose it from the menu "configurations->Cool", select "?????"
  • Click "Platform->connect"
  • Click on "Download" button
  • Click on "Start (>>)" button, and acknowledge the "start-of-run" pop-up window
  • To end a run click on "End" button

• How to kill coda processes
  • At the terminal of adaq1 (for LHRS) or adaq2 (for RHRS), type "kcoda".

Some common issues with the DAQ

Setting prescale factor for the HRS only (updated 11/03)

   For Left HRS:
 *   log in as adaq on adaq1 machine
 *   type "prescaleL &" to open the GUI
 *   set the desired prescale factors and click "Save" and Exit 

   For Right HRS:
 *   log in as "adaq" on "adaq2" machine
 *   type "prescaleR &" to open the GUI
 *   set the desired prescale factors and click "Save" and Exit 

   Definition of triggers:(Proposed for Argon- 02/07/17)
       T1 = L-arm s0 && s2 && Shower
       T2 = L-arm (s0 || s2) && (Cherenov||Shower)
       T3 = R-arm s0 && s2 
       T4 = R-arm (s0 || s2) && !(Cherenov||Shower)
       T5 = T1 && T3
       T6 = T2 && T4
       T7 = L-arm EDTM trigger
       T8 = 103.7 kHz pulser (for LHRS), 1.024 kHz (for RHRS)
       T9 = 

Starting xscaler (HRS) and checking raw trigger rates (updated nov 5, 2014)

Raw rates of trigger and detector channels can be accessed using a GUI. Below are the instructions for opening "xscaler" GUI

• These screens are generally already open on the agen5 machine (above the DAQ machine)

• If it is xscaler is not open then follow these instructions:
  • login as a-onl on adaq1 or adaq2 machines (eg: "ssh a-onl@adaq1" )
  • passwords are written on the white board
  • type "goxscaler" and follow the instructions printed on the screen
  • type "./xscaler Left" or "./xscaler Right" to access xscaler display
