1. Physics test code Phone conference 18/2 -04 Rikard Sandström Geneva University

2. Purpose Need it for probing the physics in G4MICE. It gives an inventory of particles and processes. Making it a public part of G4MICE will –allow others to run the get the same results. –allow users to test their production cuts in case they need to set a different value than the defaultCutValue.

3. The class The class is called “MICEStepStatistics”. The “Step” is to allow other Statistics classes to be written later. If a variable in dataCards is set, “StepStatisticsOutput 1”, the SteppingAction sends the step information to this special class. By the end of the run it writes the statistics summary to a file “StepStat.out”. If the variable is not set, no statistics is collected and no file written.

5. Should we use it? The code is already written, but not in CVS. Could go in Simulation, Simulation/test or MICE/test directory. Works only so far in DetOnly mode. Could print #processes/#events instead of #processes if that is more instructive.
