Setting up the analog GS DAQ from scratch
from a linux box type
telnet gsts1 2009
That will give you a console window for the analog DAQ system. In here, type 'crtl x' that will reboot the VME processor. After it has rebooted, type
</home/sga2/cur/startup_sga2.cm sgainit
Now tha DAQ is ready and you have to specify where it should store your data. We recommend the following procedure:
Place a USB disk in the the USB docking station on the machine you want to store your data on. It should automount as something like /media/20140304. To use the disk it needs to first be exported. Do that as
gsexportfs 20140304
please notice that you should not specify '/media/'
Now log into dgs1 as dgs and
cd /home/sga2/cur/config cp a cmd file to c1.cmd edit c1.cmd for your purpose
specify the directory to store the data as something like
datadir gslinux1 /media/abcd/user/tltmp
here is an example of a c1.cmd file that works on the disk named '/media/20140304' on gslinx1
#------------------------------------ # cmd file created by "savepars" command # __ on SAT MAY 11 03:04:24 2013 datadir gslinux1 /media/20140304/user/tltmp # note -- you should specify a new dir if # you have just rebooted newexp myexp myexp # note -- you may want to increment the run number below newrun myexp 5 getimewin 3950 4030 bgotimewin 1950 2030 feradelay 8 setrecversion 1 tgecomoff 4095 tbgocomoff 0 sendto gslinux1 sendfrac 100 setmode +GC_MODE setmode -TIME_VETO setmode +HC_SUPPRESS setmode +WRITE_GE_TIME setmode -WRITE_GE_FULL setmode -WRITE_BGO setmode -WRITE_ALL_GE setmode -WRITE_ALL_BGO setmode +RF_TIMING fileheader on checkebevlen 1 ratealarm off badcesdump 0
You can use this file as a template if you wish.
You should now be able to start the DAQ and see something like this:
sga2: start acquisition started sga2: EB CES switch detected, but there was no overflow flag in CES=1, usi1=0! 1083(8) ev/s; CES 50/50%; no ehi 0.5%; alarm off @ 03/05 12:30 5968(20) ev/s; CES 54/46%; no ehi 0.5%; alarm off @ 03/05 12:30 5740(20) ev/s; CES 49/51%; no ehi 0.5%; alarm off @ 03/05 12:31 5132(18) ev/s; CES 49/51%; no ehi 0.5%; alarm off @ 03/05 12:31
It migh be good to look at the data file as see that it grows as
ls -lt /media/20140304/user/tltmp/myexp
ensuring that you are taking data.
To stop the DAQ and take your data away
On the GAQ console, type
stop closeall
on the machine where you have mounted your data disk, type
gsunexportfs 20140304
using the datdisk name example from above. This ensures that we unexport the file so that we can eject the disk using the usinf the standard linux utility:
locate icon of disk on monitor click 'safely remove Drive' confirm that icon coes away type 'df' to further confirm disk is unmounted
then you can turn your disk off and remove it.
online data monitoring
cd to directory you want to use. Then get the GSSort packages as
svn checkout https://svn.anl.gov/repos/gs_analysis/GSSort . or wget http://www.phy.anl.gov/gammasphere/doc/GSSort/src/src.tgz tar -zxvf src.tgz
then compile as
make clean make GSSort
compile GSUtil_cc.so as
rootn.exe .L GSUtil.cc++ .q
Now create a chat file that looks something like this
#------------------------------------------- # input # ;input tape /dev/rmt/1mbn input net 1101 ;input disk greg.data ;input disk data/gsfma68 ;input disk /cdrom/cdrom/gsfam137_6.data ;input disk /media/disk/user/data/a1/a1.r001.dat.022 # #------------------------------------------- # output # ;output c1.root ;rootfileoption RECREATE # sharedmem c1.map 200000000 startmapaddress 0xab785000 # # #------------------------------------------- # basic sort parameters # echo nevents 1000000000 printevents 100 gerfoffset 1000 beta 0.0 hiresdatamult 0.66666666666 firstfile -1 nfiles 100 dumpevery 1 writerawfera binbgo nposwarn 10 # # germanium multiplicity requirements in sort # cleanmultlim 0 100 dirtymultlim 0 100 totalmultlim 0 100 # binpev1d tac2 8192 1 8192
Now start up roon.exe in a separate window. The first thing to do is to determine the startmapaddress in the chat file, In this case, type
.L GSUtil_cc.so sdummyload(200000000)
and enter the start addess reported in the chat file. In the other window, start GSSort as
./GSSort -chat c1.chat
you should see data come in. Now in the window where you are running rootn.exe, attach youself to the map file and update
sload("c1.map")
update()
you should now be able to see spectra as
update()
d1("sumehi")
or whatever spectra you want to look at.
VXI processsor boots
The VXI processors have dgs6 as their boot host. This is a scientific linux 6.4 blade computer sitting in the dgs rack. There is a pull out keyboard and monitor for dgs6 in the rack.
The boot parameters for the vxi processors are documented below

History: The hosting of the vxi processors was originally done by the 'shack' sun computer (which is still alive in the data room), then the hosting was taken over by the 'shack2' Dell linux box (a regular tower). We switched to the dgs6 rackmounted blade machine to save space in the shack.
