Detector simulation

The detector simulation is based on the GMINOS package written by Robert Hatcher for the MINOS experiment. In fact, it is the same program which has been and it is being used to generate evens for MINOS.

GMINOS package was developed with a very powerful and flexible geometry description language, making it possible to generate events in a liquid argon detector by a proper data cards. No wonder that the underlying data card 'language' is somewhat complicated, but it is well documented. Ask for help if you want to experiment yourself.

The principle of the Liquid Argon Detector simulation is the following:

the detector volume is sliced into thin layers along the 'z' axis. This is a virtual division, no real boundaries or related materials are simulated.

all instances of passages of charged particles through the liquid argon slice are recorded

	particle identity
	position of the entry and exit point
	total energy loss in the volume

these 'hits' can be projected onto the 'wire' at the edge of the slice to represent the signals recorded by the wire chamber

events consisting of kinematics and geometry information as well as the list of all hits are written to the data file in ADAMO format (see documentation)
