Goals for L3Muon for March 15

• March 15 will in practice be three weeks
  before that to allow time for integration
• Goals
• L3 Hardware, ScriptRunner, online system
• Tools
• unpacking
• local tracking
• Filter Script for cosmic rays

Will be simplistic If any track found then pass

Level 3 Muon Filtering on March 15
Filter Scripts
Tools
Algorithms
unpack_base unpack_mch unpack_muo_fe muo_hitreco (
Im likely to have missed one or more)
l3TMuoUnpack (in l3fMuonTools)
testing phase nearing completion
l3fMuoCosmic (in l3fMuonTools)
NOT STARTED but it will be a simplistic thing
l3TMuoLocal (in l3fMuonTools)
muo_segmentreco muo_trackreco
writing phase working on this one now
Algorithms need some more work too (suspicions of
memory leakage)
3
Segment finding

Improvements

• Hit finding needs proper calibration of
  time/drift-distance relations (driftcircles?!?)
• Segment finding works fine with MC data, but
  d-rays not well simulated - cant use neighboring
  wires
• Track finding needs implementation of
  non-uniform magnetic field

5
Conclusions

• ToDo list for the March 15 Milestone
• complete component test for unpacking algorithm
• setup test for unpacking tool interfaces
• finish tracking tool and test
• filter script
• check tracking algorithms for memory leakage
• March 15 L3Muon will filter events by performing
  tracking the muon system.
