Single particles with the SiFCC detector

You can study this the geometry of FCChh-v7 detector using sifcch7 link. This geometry corresponds to rfull009 tag SLCIO files.

We will download samples in directories dataNgev using reg. expressions. We will use 2 threads and 100 files (if available) from each sample.

hs-get pgun_pi_1to10000gev%rfull009 data1gev 2 100 pi1gev         # 1 GeV sample
hs-get pgun_pi_1to10000gev%rfull009 data10gev 2 100 pi10gev       # 10 GeV sample
hs-get pgun_pi_1to10000gev%rfull009 data100gev 2 100 pi100gev     # 100 GeV sample
hs-get pgun_pi_1to10000gev%rfull009 data1000gev 2 100 pi1000gev   # 1000 GeV sample
hs-get pgun_pi_1to10000gev%rfull009 data10000gev 2 100 pi10000gev # 10000 GeV sample

Run a Python script given here: pgun1.py. To process these samples, run this sequence. Each script creates a PDF file with the image.

fpad pgun1.py data1gev
fpad pgun1.py data10gev
fpad pgun1.py data100gev
fpad pgun1.py data1000gev
fpad pgun1.py data10000gev

A typical plot for 100 GeV single pion is shown here
