Minutes

Present:

  • CMU: Paul Mattione, Curtis Meyer
  • JLab: Mark Ito (chair), David Lawrence, Dmitry Romanov, Sascha Somov, Simon Taylor, Elliott Wolin

Announcements

  • We decided to set January 1, 2013 as the cut-off date for calibration constant changes to the file-based system, stored in the Subversion repository. After that changes will have to be entered into the calibration database (CCDB).
  • To get to the computers in the counting house via ssh, you must first log into a gateway node hallgw.jlab.org. You will need a two-factor authentication token to do that.
  • There is a plan to use an EVIO dat source and read it into Jana via an ET ring on the node in the counting house. There is also a plan to add farm management to the system.

Tracking Report

Simon gave the report.

  • He is working on propagating the track co-variance matrix to an arbitrary point along the trajectory, a feature Paul requested.
  • The CDC geometry is currently broken but is in the process of getting fixed.
  • The BCAL geometry seems to have an additional problem; the readout box is masking some of the material. This is being addressed.

David commented that in cases where there are conceptual subtleties in how the geometry is constructed, it would be very nice to have accompanying comments in the HDDS file.

Data Challenge Ststus

We reviewed current status. The goal from the last meeting was to start production today and that might still happen. Other items:

  • We will have to ask the Computer Center to restore the nodes we are using. CLAS has figured out how to use them and is expoliting their higher priority.
  • Paul requested a tagged release of sim-recon. Mark will make one.

Geometry Query Tool

David has written a tool that locates an input space point in any valid geometry, giving the volume in which it resides and that volume's parents (geneology). He found this useful when locating a target in various positions and encountering collisions in the geometry.

ROOT-based Event Display

Dmitry has started working an event display based on EVE, the event display module of ROOT.
