I want to track an event in He-3 proportional counter, in other words, a pair of proton and triton simultaneously. And the signal is the combined induced signals of the two particles. How can I realize this case?
I have no problem to track a proton or a triton, but if I created two HeedTracks for the two particles and use the same ViewDrift, then I got run-time error:
void MatterDef::verify(const String& fname, const String& fnotation): ERROR:
cannot initialize two matters with the same name or notation
FunNameStack: s_init=1 qname=1
0 void MatterDef::verify(const String& fname, const String& fnotation)
I am not sure what went wrong. Can anyone give me a hint? I really appreciate.
