Software

How to look at data with the standalone decoder:

• log on aonl as a-onl, change directory by typing "godvcs", then "cd pre_beam_dvcs"
• to replay the run
  • open the analyzer
  • <analyzer> .L combined_hall.C+
  • <analyzer> combined_hall(run number, number of event to analyze)
  • the output files are written under: /chafs/work1/dvcs/combined_hall_XXXX.root
• to look at the data (within the analyzer)
  • show_ARS_trigger: to look at a summary of all the event (adc from the trigger and integral signal for the ARS, all pedestal subtracted)
    
  • show_ARS: to look at a specific ARS event. You can look at :
    • the 16 channels of a calorimeter column: show_per_calo_column(int evt, int column, int run)
    • the 16 channels of a ARS module: show_per_module(int evt, int module, int run)
    • the 208 ARS channels ordered by column: show_calo_per_column(int evt, int run)
    • the 208 ARS channels ordered by module: show_calo_per_module(int evt, int run)
    • 16 subsequent events for a specific block: show_one_block(int evt, int run, int block)
  • to look at the integrated signal on the face of the calo (see at the bottom of this page for more info):
    /adaqfs/home/a-onl/dvcs12/onlana/marco/plotCalo/ana_cosmics_M2d.C
    Marco's comments: Here is a first version of the script with the function "plotCalo". It plots the image of the integrated wave of the calorimeter for one individual event. In this case, I'm using the function for events high signal in the whole calorimeter (to get only events with cosmics), but one can ask for a particular event number by calling the event number by evM. If needed, please ask me and I can improve the script.

Maps

On this page, one finds the DVCS calorimeter cabling map for the HV and for the ARS modules (both ARS module to block but also call block to ARS module.

This plot shows how the are module are cabled. one column represents one ARS module. ARS module 0 is the most left column. Channel 0 of a ARS module is the top row on this drawing.  <p> This table tells for each call block which ARS module and channel it is read from.

DVCS channel information Script

*** Camille will update map soon

You can find a script to obtain the same information above Julie's channel map.

[adaq@adaq1] cd /adaqfs/home/adaq/dvcs3/
[adaq@adaq1] ./DVCSinfo.exe
----------------------------------------------------
what information you have now in following ?
Trigger Number[T], Block Number[B], ARS Number[A], HV Num[H]
please input the type.... 
Note: Trigger Number which is RED number in the Julie map ? 
(Elog: https://hallaweb.jlab.org/dvcslog/12+GeV/196)
 ----------------------------------------------------
<<= you can put certain information one of them
Trigger Number[T] which is RED number on the above map.
Block Number[B]
ARS Number[A]
HV Num[H] ( Crate#[1-2] : Slot#[0-15] : Channel#[0-12] )


For example:

[adaq@adaq1 ~/dvcs3]$ ./DVCSinfo.exe
----------------------------------------------------
what information you have now in following ?
Trigger Number[T], Block Number[B], ARS Number[A], HV Num[H]
please input the type.... 

Note: Trigger Number which is RED number in the Julie map ? 
(Elog: https://hallaweb.jlab.org/dvcslog/12+GeV/196)
 ----------------------------------------------------
T
You choose Trigger Number 
103

----------------------------------------------------------------
Row:Column                    = 8 : 7 
Block Number                  = 122 
ARS Number                    = 201 
Block dimension(height:width) = 60.684 : 60.848 
HV info(Crate#:Slot#:Ch#)     = 1 :  13 : 7 
Notes                         =
