GeP ECal cosmics DAQ

• CPU : sbsvme22
• VTP : hksvtp portservhats4 port 3 geptestvxs.jlab.org
• VXS crate : 129.57.188.101

2 FADCs in slot 8 and 9

Run the DAQ

• Run CODA

1. ssh -Y adaq@adaq1
2. ssh -Y sbs-onl@adaq1
3. connect_daq_vnc (use ada password)
4. Open a terminal, and run startCoda
5. Kill CODA: kcoda

• Run DiagGUI in the VNC session

1. cd SBS-ECAL/fe_diaggui
2. ./DiagGUI ROC_sbsecal.txt

• Raw data files are saved at: /chafs2/work1/sbs/ECAL/raw/

ECAL VTP trigger

• Each block reports a hit that is above the TET threshold to VTP and its crossing threshold time.
• For a super module, if there are more than "VTP_SBS_ECAL_COSMIC_MLTP_THR" blocks having a hit within "VTP_SBS_ECAL_COSMIC_HIT_DT", it will register a trigger candidate at the time when the "VTP_SBS_ECAL_COSMIC_MLTP_THR" requirement is first met. The trigger candidate for each super module is reported.
• For all three super modules, if there are more than "VTP_SBS_ECAL_COSMIC_NSMO_THR" super modules having a trigger candidate within "VTP_SBS_ECAL_COSMIC_SMO_DT", a trigger is generated at the time units when the "VTP_SBS_ECAL_COSMIC_NSMO_THR" are met. The trigger is reported.
• VTP_SBS_ECAL_COSMIC_SMO_DT>= VTP_SBS_ECAL_COSMIC_HIT_DT

VNC connection

• ssh adaq@adaq1
• ssh sbs-onl@eel124gemdaq
• Start a VNC session: start_daq_vnc
• Connect to a VNC session: connect_daq_vnc (same password as "adaq")

Set up CODA

• Use "sbs-onl@eel124gemdaq" to run CODA
• In sbs-onl@eel124gemdaq: .bashrc, I changed
  

EXPID=EELDAQ 
SESSION=EELRP
export CODA_SCRIPTS="${HOME}/SBS-GENRP/coda_scripts"

to

EXPID=COSMICDAQ
SESSION=ECALDAQ
export CODA_SCRIPTS="${HOME}/SBS-ECAL/coda_scripts"

• Create a softlink at "eel124gemdaq": SBS-ECAL -> /adaqfs/home/sbs-onl/ecal/, and add a component table: SBS-ECAL/coda_scripts/config/ECALDAQ/coda_component_table.cfg
• Change the $COOL_HOME and $JAVA_HOME in SBS-ECAL/coda_scripts/setupCODA3.bash
• Create a configuration "ecalcosmic" with "sbsvme22" and "hksvtp" in jceidt
• Change $EXPID and $SESSION in SBS-ECAL/coda_scripts/coda_platform.sh
• Modify /etc/systemd/system/platform.service to point to the above coda_platform.sh, and restart the platform.service

Set up VTP

• Update VTP firmware as root@adaq1:

1. Update the firmware to use "fe_vtp_v7_sbs_ecal.bin" and "fe_vtp_hallb_z7.bin"
2. Put the firmware under /diskless/CentOS7-armv7/root/usr/local/vtp/params/firmwares
3. Add the host name and firmware versions to /diskless/CentOS7-armv7/root/usr/local/vtp/params/firmwares/vtp_firmware.txt

At sbs-onl@hksvtp:

• VTP configuration file: vtp/cfg/ecalvtp.cnf
• Readout list at vtp/vtp/rol/vtp_list.c

At sbs-onl@eel124gemdaq:

• Update the DiagGUI to the latest version with ECAL implemented: SBS-ECAL/fe_diaggui/

FADC

At sbs-onl@sbsvme22:

• Update the firmware to use "fe_fadc_adc_1b07.mcs" and "fe_fadc_ctrl_vxs_readout_bb.mcs" at linuxvme/fadc/firmware
• Readout list at rol/ecal_list.c
• Configuration file at cfg/fadc250/ecal.cnf

FADC Scaler

• Scaler server auto start is set at jceidt "Expert->Supervisor Process"
