Introduction

• ATLAS TiCal is

composed of: 4 Particions 64 Modules 48 Channels

• Modules are formed by

layers of scintillator and layers of steel.

4

 The light porduced for the scintillator is conduced to

photomultiplier tubes (PMTs) for fibers.

 PMTs produce a electrical signal, transmitted to ROD

(Read-Out Drivers)

5

• The signal pass for 3 CTP levels (Central Trigger

Processor).

• The energy of all channels is reconstructed in the ROD

during the first trigger level (100 kHz; 10 µs).

• Each 10 µs, you get 7 samples with information about

Amplitude, Phase and QF (Quality Factor).

• After, the signal passes to CTP Level 2 (signal of 2 kHz),

then it passes to CTP Level 3 (signal of 400 Hz).

Objective

Analyze the ntuples obtained for: DSP (Digital Signal Processors) and OPT (Optimal Filtering).

Conclusion

• The results are the expected.
• Errors are due to low statistical.
• The results of online (DSP) and offline (OPT)

methods are compatibles.
