Review of Minutes of April 22 Meeting

We generated a list of work items at the last meeting. If folks have more ideas please send them to Mark.

Cerenkov in the Default Geometry

We discussed the fact, recently pointed out by Sascha, that we have a full Cerenkov detector in the default version of the detector geometry. Beni recalled for us that when the Cerenkov was de-scoped, there was a decision made to leave it in the Monte Carlo to act as a proxy for the material of some future particle ID detector. Now that we know the initial version of the detector will not have such a device, we agreed it was better to drop it in the default geometry. It could be restored for special studies trivially (i. e., uncomment to restore). Sascha will make the change.

New Monte Carlo Features

Sascha showed a slide describing features he has added recently to our Monte Carlo system:

  • FFREAD cards for controlling:
    • supression of events with no detector hits
    • EM shower generation in the beam collimator
  • Adding start counter truth information to the data model
  • Adding a command-line option to genr8_2_hddm to allow a range for the z-vertex position

Sascha mentioned that this last feature could be added for the particle gun as a new FFREAD card. We agreed that this is a worthy project for him.

Next we got into a discussion on documentation. Several folks thought that we should have semi-formal manuals for key programs/systems in software. We agreed to discuss this further at some future meeting.
