Simulations for the HEC Prototype Module (Version 2)

This is a working area: changes are possible

Version 2 of the HEC test-beam Monte Carlo software (HEC-TB-MC) is still the version for the HEC prototype module (test runs at CERN in 1996).

The main changes w.r.t. the previous version (which is called now version 1) are the following:

• presence of leakage detectors, where kinetic energy of all particles, leaving a calorimeter module through lateral walls, through a bottom and through a rear wall, is summed;
• calorimeter hits are stored separately for different values of the time of flight (with the step of one nanosecond);
• new format of output FZ-banks, which allows easier access to all information available (here is the description of the format of FZ-banks)

These software is installed in the following area:
/home/iws109a1/atlas/lhc/testbeam/version_2

Examples of macros to run jobs and of corresponding datacards: /home/iws109a1/atlas/lhc/testbeam/version_2/job

Simulated particles: pions at Xcryostat=10.0 cm, Ytable=5.28 cm ("pad 9/90")
2000 events per each energy point

Simulated data (banks GEOM, KINE, HITS, DIGI) are kept on tapes at MPI.

FZ-banks with calorimeter cell energies and MWPC hits: /at/data1/tb_mc_2/*.bank
In the table below the size of bank-files is given.

	GCALOR		GHEISHA		FLUKA		TB run number
Energy, GeV	File name	Size, MBytes	File name	Size, MBytes	File name	Size, MBytes	Pad 9	Pad 90
20	p020n	10.2	g020n	8.0	f020n	9.8	6132	6120 6121
40	p040n	14.6	g040n	11.5	f040n	13.3	6131	6119
60	p060n	17.6	g060n	14.3	f060n	16.0	6130	6118 6227
80	p080n	20.0	g080n	16.4	f080n	18.1	6129	6117
100	p100n	22.6	g100n	18.2	f100n	20.0	6128 6239 6244	6115 6116
120	p120n	24.5	g120n	20.0	f120n	21.7	6127	6113 6114
150	p150n	27.3	g150n	22.3	f150n	23.8	6164	6185
200	p200n	31.2	g200n	25.8	f200n	26.9	6175	6176

Average CPU time per one GeV of the initial pion energy in an event equals to 1.86, 1.24 and 1.65 sec for GCALOR, GHEISHA and FLUKA respectively for the iws118b computer (see the table with MPI computer rates)

What can be found at CERN?

All files with the code were copied to the HEC test-beam disk at CERN. They can be found under the directory: /afs/cern.ch/atlas/testbeam/HEC/mc/soft/version_2
To get a working (at CERN) version of the code, it is necessary at least to make changes in the install-kumac.

Files with FZ-banks, obtained at MPI with the version 2 of the HEC-TB-MC software, are stored also on an exabyte tape at CERN. The list of them can be found in the file mc_data.log in the directory /afs/cern.ch/atlas/testbeam/HEC/mc/data.
