Question G4Transportation is killing track... 

Forum: Fields: Magnetic and Otherwise
Date: 02 Feb, 2005
From: Valentin Kozlov <Valentin.Kozlov@fys.kuleuven.ac.be>

Deal All,

using a user magnetic field profile, I frequently get the following message: "G4Transportation is killing track that is looping or stuck" (roughly in 10% cases for 1MeV electrons and 9T central field).

- First of all, can one explain a bit more, what can be a reason of such "looping etc"?

- Secondly, what exactly happens to this tracks? is the whole event killed or only at certain point this event is stopped?

I want to understand it because if, for instance, one needs to estimate the efficiency, how to interpret these type of events?

For example, I have 100 initial events, 15 of them are registred in a detector but for 10 I get above mentioned error message, so is the efficiency of registration 15 over 100 or over (100 - 10) = 90 or something else?

Thank you,

Valentin

P.S. Is there any ability to "mark" such cases in order to "look them back" in stored data file?
