Operations

to start the DAQ

• We run the DAQ from "a1.gam" (for now)

ssh -X [email protected]

• you may have to issue this command to get access to the proper fonts for the EPICS displays

 xset fp+ /usr/share/X11/fonts/75dpi

• Go to the Gretina DAQ top level directory

gt
cd 11-1/gretClust/bin/linux-x86

• Start the GRETINA DAQ MENU:xset fp+ /usr/share/X11/fonts/75dpi

$PWD/godaq

For the patience challenged, a shortcut to the above steps is

xset fp+ /usr/share/X11/fonts/75dpi
(cd /global/devel/gretTop/11-1/gretClust/bin/linux-x86; $PWD/godaq)

• The MENU below should show up:

---------- MENU ----------
  VME    	     1
  Display	     2
  Run Control	     3
  Run ControlBGS    3b
  Soft IOC	     4
  Soft IOC2	     4b
  CAEN PS	     5
  Cluster           6
  Cluster Kill      8
  Mode 2	     9
  Mode 3	     10
  Mode 4	     11
  RESET daq InBeam  12
  RESET daq Gamma   12b
  StripTool	     13
  Calibrate	     14
  
  EXIT  	     E
  KILL ALL	     K

---

• Info: Exiting the MENU does not exit the DAQ. One can return to the MENU anytime by typing $PWD/godaq

• Start things in this following order:

4, 4b, 2, 3, 6

verify you see "CA Connected" (CA: Channel Access) in the RunControl panel

• Press Button "cluster" in the GlobalControl panel to chose the correct data mode (mode 2: decomposed data, mode 3: raw data (traces))

Note: In the Gretina RunControl panel, 'new dir' makes the run starts at 0002, switching back to an existing directory makes the run start at the previous Run number + 2 

• Press button "global control"

The upcoming panel is being used for setting global parameters for ALL chrystals (baseline, polarity, etc.)
    Raw delay: For internal mode data: 3.7 usec (for analyzing the traces)
    Raw len:  length of the trace in usec 
          don't go below 0.2 usec (corresponding to 20 short words, while the header is already 16 words long, so there are 4 words left for the trace itself)
          in decomposition mode: Use 2.0 usec (corresponding to 16 words for the header and 184 words for the trace)

• Press button "TimeStamps" in the Gretina DAQ top level to check if the timestamps are still synchronized

imp sync: starts a train of imperative sync signals, by pressing the button again, the train stops
single pulse imp sync: One single imperative sync pulse

caput node0001_CS_Program1 sendRaw

caput node0001_CS_Program1 Decomp

to shut down the DAQ

• Type 8 in the MENU to kill the Cluster

• Type K (Kill All) in the MENU to kill the rest

accessing the IOC consoles

 ssh gsoper@[email protected]

you will need to know the password to gain access.

online sorting with GEBSort, to a map file

Here is an example of running GEBSort on ws3.gam on-line taking data from the GEB in a map file we can look at while we take data

o ssh -X [email protected]

o Download

 cd workdir (e.g., /home/gtuser/gebsort)
   svn co https://svn.anl.gov/repos/GEBSort .
 or
   wget http://www.phy.anl.gov/gretina/GEBSort/AAAtar.tgz
   tar -zxvf AAAtar.tgz

in a1.gam you would need to do this as well

 export ROOTSYS=/home/users/tl/root/root-v5-34-00
 export PATH=$ROOTSYS/bin:$PATH
 export LD_LIBRARY_PATH=/home/users/tl/root/root-v5-34-00/lib/root

on ws3 or ws2 you should be fine

o now compile everything

 rm curEPICS; ln -s /global/devel/base/R3.14.11 curEPICS
 make clean
 make 
 ./mkMap > map.dat
 rm GTDATA; ln -s ./ GTDATA

o to run and take data, type

#               +-- Global Event Builder (GEB) host IP (or simulator)
#               |           + -- Number of events asked for on each read
#               |           |  +-- desired data type (0 is all)
#               |           |  |  +-- timeout (sec)
#               |           |  |  |   
 ./GEBSort \
   -input geb 10.0.1.100  100  0 100.0 \
   -mapfile  c1.map 200000000 0x9ef6e000 \
   -chat GEBSort.chat 

Where in the chat file you have something like this enabled

 sharedmem c1.map 200000000
 StartMapDddress  0xab9ae000
 DumpEvery 5

4) to display the data in the map file

 rootn.exe -l 
 compile GSUtils (first  line)
 sload c1.map file (third  line)
 update          (fourth line and other places)
 display

misc problem fixes and procedures

• To fix a non-responsive timestamp, i.e. just counts and never resets, use command "caput Cry[#]_CS_Fix 1" where [#] is the bank # of the offending timestamp(s). This will reload the FPGA code and reboot the IOC. Any time an IOC is rebooted, you should press the "RESET after an IOC Reboot" button on Global Controls edm screen. Then choose the settings type you want, usually TTCS or Validate settings, on the same screen.

• to select the decomposition nodes that should be runnin (and, thus, avoid any nodes that are broken), edit the files: "setup7modulesRaw.sh", "setupEndToEnd28.sh" in the directory: "/global/devel/gretTop/11-1/gretClust/bin/linux-x86". Then do 8 to kill , then run the scripts you just changed, and 6 to bring up decomposition cluster up again. on dogs, type 'wwtop', to see details of what nodes are running.

• to bring up the GT repair buttons: "~/gretinabuttons.tcl". you may have to do that from a1.gam for now as we have a problem doing some things from the linux WS machine;
