How to list

general information

login to uvasolid2.jlab.org

1) first login to jlab gateway: ssh -X
2) from login.jlab.org, login to hallgw.jlab.org: ssh -X
You need to type your 6-digit pin followed by 6 digits pin created by mobilepass app in your smart phone.
If you do not have this setup send request to
3) from hallgw.jlab.org, login to uvasolid2.jlab.org: ssh -X ,
4) start vncviewer: vncviewer :1 (sometimes it is in :2 or :3)

how to run coda

In uvasolid2, type command "kcoda" then type "startCoda"
There are 3 configurations to use:
A) hallc_fadc: no GEM, FADC only
B) hallc_fadc_ssp: with GEM but no maroc
C) hallc_fadc_ssp_maroc: with both GEM and maroc

raw data file will be written into /home/solid/data

keep updating run list file: /home/solid/hallc_beamtest_runlist.txt

h2.how to set trigger threshold

we change threshold using diaggui, which requres root.
A) source /home/solid/event_viewer/beamtest_hallc_decoder/setup_daq.sh
B) cd /home/solid/fe_diaggui
C) ./DiagGUI ROC_sbsvme22.txt
D) click on "18:DSC2" in the laft pannel, then click on "TDC Config" in the middle pannel, then click on "Thresholds"
Before you updated the threshold, you need to start coda and finish 'download'

In case sbsvme22 is rebooted, or vmecrate is rebooted, you have to restart diaggui.
If coda crashes, I highly recommend restarting diaggui.

vmeDSC map:
TS1: DSC01 (CerSum, 25mV) & DSC03 --> PS1>=5
TS2: DSC06 (SC_B, 35mV) & DSC07 --> PS2>=11
TS3: DSC05 (SC_A, 31mV) & DSC08 --> requires I<20uA, PS2>=10
TS4_low: DSC14 (ShowerSum, 15mV) --> PS>=10 for 40uA
TS4_high: DSC14 (ShowerSum, 230mV) -->keep PS4=0, 40uA(230mV-->2.7kHz)

how to change trigger
A) login into sbsvme22: ssh sbsvme22
B) cd rol
C) update ti_list.c,

line 62-64 to enable|disable pulse trigger:

//TI_SYNCEVENT_CONFIG tiSyncEventConfig = {1, 1000, 100, 0, 83}; //first 100k pulse trigger of 100kHz
//TI_SYNCEVENT_CONFIG tiSyncEventConfig = {1, 1000, 3000, 0, 830}; //first 3M pulse trigger of 10kHz
TI_SYNCEVENT_CONFIG tiSyncEventConfig = {0, 1000, 0, 0, 83}; // disable pulser trigger

line 111-122 for trigger type:

/* Enable set specific TS input bits (1-6) */
tiEnableTSInput( TI_TSINPUT_1 );
//tiEnableTSInput( TI_TSINPUT_1 | TI_TSINPUT_4 );
//tiEnableTSInput( TI_TSINPUT_1 | TI_TSINPUT_2 | TI_TSINPUT_3);
//tiEnableTSInput( TI_TSINPUT_1 | TI_TSINPUT_2 | TI_TSINPUT_3 | TI_TSINPUT_4);
//tiEnableTSInput( TI_TSINPUT_ALL );
//tiEnableTSInput( TI_TSINPUT_1 | TI_TSINPUT_2 | TI_TSINPUT_4);
//tiEnableTSInput( TI_TSINPUT_2 | TI_TSINPUT_3 | TI_TSINPUT_4);
//tiEnableTSInput( TI_TSINPUT_2 );
//tiEnableTSInput( TI_TSINPUT_3 );
//tiEnableTSInput( TI_TSINPUT_4);
//tiEnableTSInput( TI_TSINPUT_6 );

Line 147-152 for prescale factors

//for 40uA beam on LD2 target
tiSetInputPrescale(1,7);
tiSetInputPrescale(2,11);
tiSetInputPrescale(3,8);
tiSetInputPrescale(4,0);
tiSetInputPrescale(6,0);

how to cook data in uvasolid2
A) source /home/solid/apps/setup_rh8.sh
B) you can choose to cook data with or without tracking.
B1) cook 10k events with tracking, using 10adc peak finding threshold:
replayFiles_18deg.csh '-x 1 -n 10000 -t 10' /home/solid/data/hallc_fadc_ssp_4580.evio.0

usage: /home/solid/event_viewer/beamtest_hallc_decoder/bin/replayFiles_18deg.csh <'replay_option'> &lt;File_List&gt;
example 1: replayFiles_18deg.csh '-n -1' hallc_fadc_ssp_3049.evio.?
example 2: replayFiles_18deg.csh '-m /home/solid/event_viewer/beamtest_hallc_decoder/database/modules/mapmt_module_highrate.json -n 50000' hallc_fadc_ssp_3049.evio.2 hallc_fadc_ssp_3049.evio.3
replayoption must be single-quoted, here is a list of them:
usage of build/src/analyze:
build/src/analyze [-n NEV] [-m, --module MODULE] [-r RES] [-t THRES] [-p NPEDS] [-f FLAT] RAW_DATA ROOT_FILE
-h, --help: print help message
-n [NEV (default: -1)]: number of events to process (< 0 means all)
-m, --module [MODULE (default: database/modules/mapmt_module.json)]: json file for module configuration
-r [RES (default: 3)]: resolution for waveform analysis
-t [THRES (default: 20.000000)]: peak threshold for waveform analysis
-p [NPEDS (default: 8)]: sample window width for pedestal searching
-f [FLAT (default: 1.000000)]: flatness requirement for pedestal searching
-x [USEFIXEDPED (default: 0)]: whether or not to use fixed FADC pedestals from database
the output will be stored at /home/solid/replay/GEMROOTFILE, monitoring histogram and graph will be stored at /home/solid/replay/monitor

B2) cooked 100k events without tracking, using 10adc peak finding threshold:
replayFiles_highrate.csh '-x 1 -n 100000 -t 10' /home/solid/data/hallc_fadc_ssp_4580.evio.0

the output will be stored at /home/solid/replay/ROOTFILE, monitoring histogram and graph will be stored at /home/solid/replay/monitor

how to transfer raw data to /cache:
rsync -avzhe ssh --progress --remove-source-files /run/media/solid/Data16T/data1/ /DISK4T/data2/ jixie@ifarm1802:/cache/halla/solid/subsystem/ec/ecal_beamtest_hallc_18deg/raw

where is the cooked data in the farm

A) raw data: /cache/halla/solid/subsystem/ec/ecal_beamtest_hallc_18deg/raw
B) cooked root file: /volatile/halla/solid/$user/ecal_beamtest_hallc/18deg/ROOTFILE
C) 50k events cooked with tracking: /volatile/halla/solid/$user/ecal_beamtest_hallc/18deg/GEM50k
D) cooked with tracking root file: /volatile/halla/solid/$user/ecal_beamtest_hallc/18deg/GEMROOTFILE

E) once the decoder software is frozen, will put pass0 cooked file here: /cache/halla/solid/subsystem/ec/ecal_beamtest_hallc_18deg/replay/pass0
