Taking cosmic data in the ESB and setting HV

1. ssh into genl5 (computer in ESB), even if you are already on the machine (to make sure css loads correctly)
2. Do not source coda_bcal_setup in /home/halld/bcal_test
3. type 'css' to bring up the slow controls HV gui
   • If an error screen comes up try to the following:
     1. ps -ef | grep BCAL (to get localhost id)
     2. telnet localhost 20000 (or other from ps command)
     3. ctl-x (reboots server)
     4. ctl-] (escapes to telnet prompt)
4. For cosmics in ESB use 'halld' account instead of 'halldrun' and use 'genl5' computer instead of 'clonusr2'. 'halldtrg3' is still used. Otherwise, follow instructions below
5. When css looses communication, reset the crate as follows
   • Turn power off
   • Unplug ethernet (blue) cable
   • Turn power back on
   • Plug ethernet cable back in

   • emacs raw_check2.C &
   • Change the run number on the line with Int_t runno=###;
   • Save the change using the down arrow below the 'Buffers' command

• To look at the data, in the /home/halld/bcal_test/data directory type

1. bcal_beam simple_855.evt.0 (using the correct run number)
2. root
3. root [0] .x raw_check2.C (can use the up arrow)
4. hit return twice for the data to be displayed
5. hit Cntrl-c (to get back to the root prompt
6. root [0] .q (to exit root)

Store data on tape

• To store data on tape just copy files on clonusr2 to

/w/stage/output/clas/test

To retrieve files, go to ifarms ( ssh ifarml64 ). You can see files using

ls /mss/clas/test/bcal*

• To retrieve a file from the tape use

jget /mss/clas/test/file_name .
