Aim & algorithm
• Dynamic range is a quantity essential for design of the read-out
chips.
• Determination of the energy deposition at each cell of the muon
chambers ( in terms of MIP as muons give MIP signal).
• Take different cell sizes (2mm. – 4cm.) & find out the fraction of
multiple-hit cells & singly-hit cells for particles generated by UrQMD.
• Optimize the cell size based on multi-hit fraction.
• For the optimal cell size find cell by cell energy deposition (E_dep)
both for single muons (MIP spectra) & UrQMD particles.
• Apply different MIP cuts & calculate the loss due to saturation.
• Apply different hit cuts to observe the effect on tracking.
Comparison of percentage of track lost using different signals as
input
signal-1. hit loss track loss I. Signal is 25 mu+ & 25 mu-
5% 6.76% added using Box generator in
10% 18.55% each event along with UrQMD
II. Signal is 50 mu+ & 50 mu-
signal-2. 5% 7.58% added using Box generator in
10% 19.1% each event along with UrQMD
III. Signal is 100 mu+ & 100 mu-
signal-3. 5% 7%
added using Box generator in
10% 19.16%
each event along with UrQMD
