1. 1 PLU [need 1 as spare] for 4 input from scintillators
   1. Exit goes to
      • TDC trigger
      • WFD trigger

2. Dual timer: needed to implement busy

1. Splitter [Splitting cables?? will save module]
   • Needed to split the output of Scintillators to TDC, WVD

   • Currently available only 8 chs : 2*8 chs missing
3. Coincidence Unit
4. I/O Register
5. Converter

6. Fast TDC
   • 64 Channels available [OK]
7. WaveForm digitizer
   • 8 Chs available with sampling @ 500 MHz [OK?]

The acquisition code is compiled on the CPU. Performs the reading of the various modules (returning each a vector with the needed information) and also the event writing. Writing is implemented as unformatted/binary.

1. Hardware: CPU
2. Code location: /home/daq/CT
3. Running instructions:
   1. compile with make acquire
   2. run with ./acquire + options.

Provided options are:

1. [-n] : number of events to be acquired
2. [-p] : number of events on which the ACQ rate is computed
3. [-f] : Full path to output file (binary, unformatted)
4. [-z] : switch on and off of zero suppression

1. Hardware: PC daq
2. Code location: /home/daq/acq
3. Running instructions:
   1. compile with make Analizer
   2. run with ./Analizer + options

Provided options are:

1. [-in] : full path top input file (link to data/ dire of acquisition is provided)
2. [-out] : output root file

1. Evt num
2. Num boards
3. Then for each of the boards in the event: b{j}_nwords [j=0,N_boards]
4. Then for each of the boards in the event: b{j}_words{i} [j=0,N_boards][i=0,b{j}_nwords]

Boards order:

1. IOREG
2. TDC1190
3. WVD

To be implemented

1. 1w →Evnum
2. 3w*n_firing_cha →For each firing channel 3 words containing event number channel and measurement are stored
3. 1w →Trailer (possible check of errors)

To test the zero suppression you need to test the 3rd word of the event, checking the 24th bit (if == 1 → zs data): data»24 & 0x1;

1. if zero suppression
   1. 1w → n of words in the event
   2. 1w → falg for checking ZS data
   3. 1w → mask of enabled channels
   4. 1w → Trigger time
   5. Then For each channel
      1. 1w → Total channel words [included this one]
      2. 1w → Number of 32 bit words skipped
         1. nsam*1w → Number of words with samples over threshold
         2. 1w → Number of 32 bits skipped
2. else
   1. 1w → n of words in the event
   2. 1w → falg for checking ZS data
   3. 1w → mask of enabled channels
   4. 1w → Trigger time
   5. 512w*ncha → 512 words for each enabled channel

1. Test TDC
2. Calibrations
