A [[Instructions for shift takers|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  [https://hallaweb.jlab.org/wiki/index.php/Graduate_Students tritium students] with updates.

=How to manage your BTA (for Shift Leader)=
 
 
 
Open your browser on an a-onl@aonl machine<br>
 
[1] https://bta/<br>
 
[2] <b>Login your name/pass word</b><br>
 
[3] File->Open Timesheet<br>
 
[4] choose: Hall:A -> Day-> Shift: Owl(or Day/Swing)<br>
 
[5] click "Open"<br>
 
[6] You see the address bar: <br>
 
(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<br>
 
<br>
 
Instead, do the following
 
  https://bta/experimenter/a/2014-12-16/owl/<br>
 
[7] If you want to edit hour(s), Please click very right "pencil" icon, then make a comment or edit time<br>
 
<font color>DO NOT USE *EDIT ALL* ON THE BOTTOM</FONT><BR>
 
[8] To save your edited info into DATABASE, just click "V" (check-mark) in same place of "pencil" icon<br>
 
[9] When MCC call you for BTA (An hour before your shift end), click "SAVE INFO for MCC"<br>
 
[10] Read number ABU and BANU. (That's it ! This should work !)<br>
 
[11] <b>End of shift, please sign off</b><br>
 
[12] <b>Once you've done, please Logout. </b><br>

=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 [[https://logbooks.jlab.org/entry/3313926 logbook entry.]]
 
 
 
= Beam Recovery Procedure =
 
 
 
Update: October 24, 2010.
 
* Empty target, establish correct beam position</li>
 
** 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 | 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"'''.

    For Left HRS:
 
        login as adaq on adaq1 machine
 
        type "prescaleL &" to open the GUI
 
        set the desired prescale factors (for DVCS enable prescale 9 only)  and click "Save" and Exit
 
 
 
    For Right HRS:
 
        login as "adaq" on "adaq2" machine
 
        type "prescaleR &" to open the GUI
 
        set the desired prescale factors and click "Save" and Exit
