Spherical Particle Distribution Around Target for Chromium Replay

Analyzing particle distribution around a target with uniform θ and φ in GEANT4 for Chromium replay. Event number increased by 15%. To-do: Generate particles in narrower region, check new data details, and prepare for JPS collaboration meeting and Master's thesis.

  1. HES HKS meeting 2010/2/24 T.Gogami

  2. θ , φuniform distribution Last week φ : 0 – 2π θ : 0 – π/2 θ= π * G4UniformRand( ) /2 φ= π * G4UniformRand( ) xp = px/pz =sinθ・cosφ/cosθ • xp = py/pz =sinθ・sinφ/cosθ

  3. Particle distribution around target r=1 [cm]

  4. θ , φuniform distribution φ : 0 – 2π θ : 0 – π/2 θ= acos( G4UniformRand( ) ) φ= 2 * π * G4UniformRand( ) xp = px/pz =sinθ・cosφ/cosθ • xp = py/pz =sinθ・sinφ/cosθ

  5. Particle distribution around target r=1 [cm]

  6. Chromium replay • 2/17 condor start (170 runs)  still running • Replay 1 run ~ 24 [hours] • Event number ~15 [%]↑ replay  ifarm h2root  tfarm replay  farm h2root  farm Check details later number of kaon etc.

  7. Summary and to do • Sum • Spherical uniform distribution (GEANT4) • Replay for Chromium target • ~24 [hours/1 run] • Event num. ~15 [%] up (rev.256rev.354) • To do • Spherical uniform distribution (GEANT4) • Generate particles in narrower region • Solid angle (HES , HKS) • Chromium • Check details of new analyzed data • Collaboration meeting , JPS • Master’s thesis
