Revision as of 14:04, 21 June 2022

meeting time and location

Simulations/Analysis
- Updated single photon and diphoton FCAL position plots -- TB
Preparation of parts for FCAL2 modules -- Sasha
- Summer Students (2022)
- Moving crystals from JLab's pool to the Lab [1][2] Moved 335 CRYTUR crystals (need 550).
- Preparation of parts[3][4][5]
  - Preshaping ESR foils
  - Wrapping crystals
  - Module fabrication
- Wrapped CRYTUR crystals
- Students reports
Module fabrication -- Sasha
- Status of fabrication
- Fabricated modules (list on Google Drive) Grand total 519
- Clean room EEL126
Light Monitoring System -- Arshak

Attendees: Bill,Sasha,Zisis,Phil,Igal,Tegan,Olga,Axel,Arshak,Azizah,Liping,Jon,Jaden,Dax,Christopher,S.T.

Eugene to order 100 more crystals this fiscal year, 100 more next fiscal year
Ordered more ESR and mu-metal
Brazing is lagging behind other preparation steps
Dax and Jaden presented slides showing all their efforts toward module construction
Grand total number of fabricated modules up to 519 as of the Friday meeting
Arshak working on addressing light intensity profile as a function of in plexiglas for LMS
Tegan gave an update on reconstruction of single photon and di-photon clusters in FCAL-1 and FCAL-2 using default and island algorithms
- log-weighting cluster positions biases toward small apparent cluster separation compared to thrown separation
- FCAL-2 reconstructed energy biased toward higher energy
