Hi, I made a few fixes to SLIC/LCDD for the support of 3D magnetic field maps. The map’s offsets were not being set correctly, and I believe this is now fixed in the HEAD configuration of SLIC in ilcinstall. I also added the missing field data to the SVN at hps/java/trunk/fieldmap which is referenced by the detector that includes the field map. I was able to get simple visualization working with the 10.00.p01 release of Geant, and the best picture I have so far is this: http://www.slac.stanford.edu/~jeremym/hps/field/hps_field7.png This visualization tool is at an “alpha” stage of development in that project, unfortunately, but it at least gives some idea that the field has been loaded in successfully. That’s the good news. The bad news is that the performance is approximately 150x worse when using the 3D field in a Proposal2014 geometry compared to a setup with the simplistic fixed dipole. This compares the HPS-Proposal2014-v5-2pt2 detector with HPS-Proposal2014-v4-fieldmap using the event file egs_tri_2.2gev_0.00125x0_200na_5e5b_30mr_001.stdhep. So it appears to me this is not really going to be useable in large scale simulation production until the algorithm for retrieving and interpolating the field values has been significantly optimized. —Jeremy ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
