Schedule

• Giovedi' : carichiamo il pulmino, arriviamo ai LNF, cominciamo a installare
• Venerdi', installazione: messa in tempo e cosmici.

Obiettivi fondamentali:

• Ar/CO2 80/20, 90/10: soglie e tensioni.
• Studio del PM10.
• RPC: studio in funzione di E ed angolo

Proposta

• Lunedi': timing con il fascio (BM) + RPC

Software

DAQ

The acquisition software is under the server, daq account, BTF_2011_cpu directory.

In order to run the acq you need to issue the command

• acquire -n #evts -p #frequency check -f #filename

in order to stop it while running you need to type

• touch acq.stop

Analizer

The software for the data processing is being developed. Latest stable version can be found on the server under the daq account, BTF_2011_ana directory.

In order to process the data that has been acquired you can use the Analizer exec.

• To check for the run options you must type ./Analizer -help
• Most simple analizer is ./Analizer -in #datfile -out #rootfile -con #configfile
• CPU data can be found under the softlink data_cpu

Before processing the data to create tracks and study efficiencies/resolution, the t0s have to be determined. You can use the t0dch_new.C macro , after having properly edited the input and output files. The t0s are loaded in AnaTools.cc: the input are in AnaTools.h and are hardcoded TO BE CHANGED !!!

To produce the ST relations

• You need to enable the fit in the configuration file (see conf_140211.txt)
• On the output of the 'fitted' events you need to run a macro: Ex. root -b -q macro/STRelations_Btf.C\(\"st0\"\,2100) [to process the first round [flagged as st0, see the macro inside] @ 2100V]
  • The output of the macro is a root file containing the Splines that needs to be used for the ST correction.
  • The output file needs to be listed in a txt file (with relative path to where the user is running the Analizer) and fed to the next reconstruction round using the -str files_with_names_of_root_strel.txt option
• An example of a running cycle is
  • ./Analizer -in list_2300.txt -iL -out rootfiles/ACQ_2300_st0.root -con conf_140211.txt [no st applied]
  • root -b -q macro/STRelations_Btf.C\(\"st0\",2300\)
  • The you need to create/add the spline file to the txt file: file_stlist_2300.txt
  • ./Analizer -in list_2300.txt -iL -out rootfiles/ACQ_2300_st1.root -con conf_140211.txt -str file_stlist_2300.txt [applied ST rel.. the corrections applied are those contained in the files listed in the txt. those files need to be created with the STRelations_Btf macro]
• To check the residuals after fitting you can use a macro:Ex. root -b -q macro/Residual_Btf.C\(\"st0\",2100\)

Example for producing/running automated ST relations on full long data sample

1. ls data_cpu/*long*dat > list_2200_long.txt
2. ./Analizer -in list_2200_long.txt -iL -out rootfiles/ACQ_long_all_2200_st0.root -con conf_140211.txt [level 0 processing, no ST]
3. remove OLD ST files : rm spl/spline_Btf_160211_long_2200_st*
4. root -b -q macro/STRelations_Btf.C\(\"st0\",2200\)
5. \rm file_stlist_2200_long.txt
6. ls spl/spline_Btf_160211_long_2200_st* > file_stlist_2200_long.txt
7. ./Analizer -in list_2200_long.txt -iL -out rootfiles/ACQ_long_all_2200_st1.root -con conf_140211.txt -str file_stlist_2200_long.txt

Points 4 -> 7 needs to be iterated as shown in the strelscript.sh script

Configuration

Trigger time is stored in TDC channel 58 and its charge in QDC channel 8. The trigger is the Beam Dump

Log Book

Trigger config: scintillators are @ 1.6 kV & 1.3 kV with thresholds @ 25 & 20 mV after splitting.

Mapping config: U view (flag 1) is the TOP view. V view (flag -1) is the SIDE view.

Eventi

• 14/02 Ore 16:00 Rate osservata ~10 Hz, Aspettata 15Hz.. Studio per capire l'efficienza di trigger... si cambiano le HV degli scintillatori
