[Halld-cal] Previous Neutral Detection in Calorimeters

[Mark-Macrae Dalton]

Hi Tolga,

The best way to study the calorimeter response to neutrons is to isolate a sample of neutrons in the data.  A good final state for this is pi+n because requiring coplanarity works well to enhance purity.  This final state has been looked at before but not with the view towards understanding the calorimeter response, as far as I am aware.  This could be a good project.  Having said that, it might be sufficient for your purposes to start by looking at a sample of simulated neutron events.  If you would like we can discuss this by phone.

Hi all,
I wanted to reach out and ask if, out of past reactions with neutrals in the final state, particularly neutrons, there were any results out there showing the BCAL response in those reactions? I recall pi+n has been studied but only found beam asymmetry plots. I am aware of Andrei's talk from last year and find the information useful, however I believe there are more reference-able results out there. If there are, I would greatly appreciate having the chance to read through and study how the calorimeter should behave so I know what to expect in the (neutron/antineutron) channels I'm looking at.

Thanks,
Tolga
