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
• Martedi': tunare beam + RPC
• Mercoledi' / Giovedi': Ar/CO2 80/20. Cambiare 2 Soglie. Poi cambiare tensioni: 2-3 punti
• Venerdi' / Sabato: PM10 .. vari punti a differenti tensioni.
• Domenica: Ar/Co 90/10....

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

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.
