  1. HBD Software Update By Sky Rolnick UC Riverside

  2. Online Production Code • Will modify PHCentralTrack to hold hub n’ spoke variables. • These include hubcharge, spokecharge1, spokecharge2,etc. UC Riverside

  3. Online Monitoring Tools • Will modify HBDMon.C (written by Zvi) to allow High Voltage scans to optimize bias voltage. • Code now compiles on va machines. • Requires data to be stored after each run. How to store data? • Option 1) Using Database • Option 2) Simple Text file UC Riverside

  4. Online Monitoring • Plot Run 265929 UC Riverside

  5. Simulations Update • Generated 10K single particle (electron, phi) using EXODUS. • Generated 10K pp minbias at 200GeV & 500GeV using PHPythia. • Generated 10K AuAu at 200GeV using HIJING. • Run through PISA with full HBD in +- field configuration. UC Riverside

  6. Questions Remain • How to include scintillation light? • This can be done in HbdFinalSimulator.C or it can be done in PISA. Which one? • How is Cherenkov light simulated for low pt electrons? Does it take into account tracking curvature? UC Riverside

  7. HBD Reconstruction - issues with AuAu PisaToDST – • Warning in <TFile::Init>: file /direct/phenix+data08/skymeson/runjobs/AuAu_minbias/pisa/11/simDST.root probably not closed, trying to recover • Warning in <TFile::Init>: no keys recovered, file has been made a Zombie • Warning in <TFile::Init>: file /direct/phenix+data08/skymeson/runjobs/AuAu_minbias/pisa/11/simDST.root probably not closed, trying to recover • Warning in <TFile::Init>: no keys recovered, file has been made a Zombie • /home/phnxbld/new/source/offline/framework/fun4all/Fun4AllDstInputManager.C:114: : in Could not open file /direct/phenix+data08/skymeson/runjobs/AuAu_minbias/pisa/11/simDST.root • /home/phnxbld/new/source/offline/framework/fun4all/Fun4AllDstInputManager.C:645: could not open file: /direct/phenix+data08/skymeson/runjobs/AuAu_minbias/pisa/11/simDST.root UC Riverside

  8. Embedding Events • New code allows embedding, ie. Signal + Background. • merge(HbdCellList *hcl1, HbdCellList *hcl2) { // work in progress here. } UC Riverside

  9. Hub n’ Spoke Clustering cvs co offline/analysis/HbdHnSCluster/ UC Riverside

  10. Hub n’ Spoke Event Display cvs co offline/analysis/HbdHnSDisplay/ UC Riverside

  11. Hub n’ Spoke Mapping UC Riverside

  12. CGL Projections UC Riverside

  13. Remaining Issues • Mapping may have bugs, ie. sometimes padkey not found, does not give expected charge in hub n’ spoke. • Still need to code spoke radius = 2. • Still need to compute COG for hub n’ spoke. • Still need to test efficiency of algorithm for identifying “single” and “double” events. UC Riverside

  14. Conclusions • Progress has been made. • Still lots of work remaining before we start taking data. UC Riverside
