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 root file

Here is an example of running GEBSort on a1.gam on-line taking data from the GEB

1) Download and compile

 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
 rm curEPICS; ln -s /global/devel/base/R3.14.11 curEPICS
 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
 make GEBSort

2) to run and take data, type

  ./GEBSort -input geb  10.0.1.100    100 0 100.0 RECREATE \
  -chat GEBSort.chat \
  -rootfile test.root &

3) to stop the on-line sort and write the root file out, type

 ./stop.sh

4) to display the data

 root-l
 compile GSUtils
 dload root file
 display

online sorting with GEBSort, to a map file

Here is an example of running GEBSort on a1.gam on-line taking data from the GEB

1) Download and compile

 cd workdir (e.g., /home/gtuser/gebsort)
   svn co https://svn.anl.gov/repos/GEBSort .
 or
   wget http://www.phy.a  rm curEPICS; ln -s /global/devel/base/R3.14.11 curEPICS
 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

nl.gov/gretina/GEBSort/AAAtar.tgz

   tar -zxvf AAAtar.tgz
 rm curEPICS; ln -s /global/devel/base/R3.14.11 curEPICS
 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
 make GEBSort

2) to run and take data, type

  ./GEBSort -input geb  10.0.1.100 100 0 100.0 RECREATE -chat GEBSort.chat
  -chat GEBSort.chat  &

[note RECREATE does not make sense, needs to be changed]

Where in the chat file you have something like this enabled

 sharedmem c1.map 200000000
 StartMapDddress  0xab9ae000
 DumpEvery 5

3) to stop the on-line sort and write the root file out, type

 ./stop.sh

4) to display the data

 rootn.exe -l
 compile GSUtils
 sload root file
 display

problem fixes

• 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.
