Hardware

Vista Top, plane 0 closest to the beam.

Schedule

• Lunedi' : Installazione
• Martedi': Debug acquisizione + run Panda

DAQ

• Crate sono direttamente alla Btf.

Software

DAQ

The acquisition software can be found in the top link at top of that page.

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

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

• touch acq.stop

Analizer

The software for the data processing is being developed. You can get (download) the latest version with the instruction reported @ top of that page.

Configuration (implemented in the configuration file conf_180411.txt):

• TDC: Chn 0-31 --> Chamber
• TDC: Chn 32-33 --> Sipm
• TDC: Chn 48,50 --> Calo, RF (trigger)
• TDC: Chn 51,52 --> PMT's
• QDC: 0, 3, 4, 5, 6 --> Calo, Sipm 1, 2, PMT 1, 2

Data

All the runs taken during the test beam can be downloaded from THIS LINK

Making and running

After having downloaded the package you can compile the analizer by issuing the command

make Analizer

or, if you are using a Mac

make -f makefile_mac Analizer

Before that you need to have ROOT installed. To check the options available in running, after having compiled the executable, you can run it using -hepl option

./Analizer -help

The output will be

Analizer help:
 Ex: Analizer [opts] 
 possible opts are:
      -out path/file : [def=dumb.root] Root output file
      -in path/file  : [def=../data/test.txt] Unformatted input file
      -con path/file : [def=conf_test.txt] Configuration file
      -str path/file : [def=11009_1] S-T relations name from spline files
      -deb value     : [def=0] Enables debugging. Values 1,2 are allowed
      -nev value     : [def=10^7] Numbers of events to process
      -evd value     : [def=0] Enables the event display
      -pla           : if present store the Root-pla with the event info

In order to run on a given run using the already existing ST relations (see next paragraph) and producing an ntuple with decoded information you can use the command line

./Analizer -in data/Run_32_200411.dat -out rootfiles/Run_32_200411.root -con conf_180411.txt -str spl/file_stlist_2000.txt -pla

A script to perform 'standard' Run decoding is provided as well:

./processRun.pl Run_32_200411

will take run Run_32_200411 data from data/Run_32_200411.dat and produce the output rootfiles/Run_32_200411.root

Tuple analysis

To access the decoded data an executable is provided: AnaTup.

You can build it using the command

make -f make_anatuple AnaTup

and you can process a given tuple using the command

./AnaTup -f rootfiles/Run_64_210411.root

Producing ST relations

The ST relations can be produced by running the strelscript.sh script that takes as input the Run n. 53 (-in data/Run_53_200411.dat) and provides the ST relations applied in the analizer. ST files are kept in spl and relative plots are produced in directory plots

Eventi

• 18/04: installato il tutto
• 19/04 mattina: arrivano gli scintillatori e si riesce finalmente a far partire l'acquisizione.
• 19/04 : Ore 17. Dopo aver sostituito il crate nim, finalmente vediamo i tempi della camera e della RF
• 19/04 : Ore 18:30 big con Sipm=posizione 3; Small con Sipm=posizione 3; Big con PMT=posizione 3; Small con PMT=posizione a caso.
• 19/04 : Ore 19:40 tolti gli scintillatori con PMTs; iniziato lo scan in posizione
• 19/04 : Ore 22:20 stop scan in posizione scintillatori. Durante la notte cameretta a 2 kV e pallino ai panda. Si spera di fare T0 e ST relations
• 20/04 : Ore 11:20. Rimesso in posizione Small Sipm e Fotomoltiplicatori. Camera ancora a 2. kV. Soglie SIPM @ 42 mV, Soglie PM @ 20 mV.
• 20/04: Ore 16:40. Cambio soglie Sipm da 42 mV a 10 mV (il valore di tensione letto sulla scheda va diviso per un fattore 4.5)
• 20/04: Ore 17:40. Cambio soglie Sipm da 10 mV a 30 mV (segnale affogato dal rumore)
• 20/04: Ore 19:35. Inizio scan in posizione Big Sipm e PMT. Soglia Sipm=30 mV
• 20/04: Ore 22:30. Rimossi scintillatori. Set-up PANDA
• 21/04: Ore 11:00. Si parte con lo scan in soglia e guadagno dei Sipm (scintillatore grande davanti, piccolo dietro)
