Review of Last Meetings Minutes

We went over items from the last meeting. Most of the issues left over from last time were addressed in the review of action items below.


  • David: A bug in Jana has been found, having to do with multiple threads setting configuration parameters at initialization. This was only discovered when running many tens of threads under a single process. It has been fixed.

elliott: halld group changeover done elliott: interview during online meeting

target individuals and ask for slides

ask tim about mechanical drawing access

perhaps a greatest hits

raid 6, $1200, 9 TB

simon, tracking meeting presentation, does not look like we need the half-cell offset. chisq distributions look similar eugene, result may depend on starting point, may induce ambiguity mis-resolution can throw with correct parameter, not using standard candidate finding (helical fit). Explanation of finding and fitting

???do the other layers in the default geometry help resolve l-r in a given layer???MMI answer is yes

???kalman filter reference???

poisson: some maps generated, 4x # points tried successfully along beam line discreprency with ansys compare field directly run more simulations compare resolutions

beni: structural elements in cdc have been added, mm of plastic on inside what about this

al skin checked

put 1 mm skin-> Beni

yves sent in drift time to distance resolution, mcsmear cell dependent smearing function
