1. Updates to Tracker Digitization Jeremy McCormick, SLAC

2. Overview configure detector parameters independent of compact.xml file –strip pitch, transfer efficiencies, etc. configure all parameters of digitization algorithm (sisim) –cluster sizes, thresholds, etc. make easily steerable from recon xml for batch processing package: org.lcsim.recon.tracking.digitization.sisim.config example job: lcsim/testResources/^^^^/digiTest.xml

3. Detector Setup Drivers SiTrackerBarrelSetupDriver SiTrackerEndcapSetupDriver SiTrackerEndcap2SetupDriver readout pitch, sense pitch, transfer efficiencies (2 numbers) SiVertexBarrelSetupDriver SiVertexEndcapSetupDriver readout pitch x & y, sense pitch x & y, transfer efficieny (1 number)

4. Digi Configuration Drivers StripDigiSetupDriver –subdetectorNames, rawHitsCollectionName, trackerHitsCollectionName –maxClusterSize, noiseIntercept, noiseSlope, noiseThreshold, readoutNeighborThreshold, seedThreshold, neighborThreshold, centralStripAveragingThreshold, one/two/three/fourClusterErr PixelDigiSetupDriver (similar to above)

5. Detector Setup: Example XML SiTrackerBarrel 0.050 0.025 0.986 0.419

6. Digi Config : Example XML <driver name="TrackerDigi“ type="org.lcsim.recon.tracking.digitization.sisim.config.StripDigiSetupDriver"> SiTrackerBarrel SiTrackerEndcap TKR_RawTrackerHits TKR_TrackerHits 10 300. 30. 9000. 4 0.288675135 0.2 0.333333333 0.5 1.0

7. Example Batch Job: Execution Detector Setup Link hits  sensors Digitization Makes HelicalTrackHits Write LCIO File

8. TODO xml jobs easily runnable from JAS3 for event display, debugging, etc. detector description drivers fully configurable including selection of p/n side, stereo angles, etc. (what else?) generate strategy file and run with seedtracking (only up to HelicalTrackHits right now) run on sidloi detector instead of test model
