Agenda
- Announcements
- Maria's RICH 2018 slides
- Optical box
- Fabrication status update (Ernie and Jason)
- Component QA and assembly status at Bates
- Window procurement: delivery date to JLab?
- Assembly sequence and testing plans at Bates
- Dark box design: Air flow considerations and plan:
- The power dissipated by each module is ~4 Watts, so the total in one optical box enclosure would be ~144 W.
- Maintain temperature < 50 C inside the box to keep local FPGA temperatures < 80 C
- Uniform flow over electronics boards (Jason)
- PMT test fixture and cookies (Maria)
- Fabrication status update (Ernie and Jason)
- Installation schedule discussion:
- Requirements for mechanical install of optical box: Aug 10 installation schedule
- Delivery of outer optical box (mirror box not required), window, flange, and gasket by August 10
- Goals (reduce risk for final installation):
- Test water tightness of optical box and interface with bar boxes
- Flow water through full system and establish controls, N2 purge, etc.
- Requirements for mechanical install of optical box: Aug 10 installation schedule
- Mirror box laser alignment
- Cabling and DAQ integration
- Cabling progress (Tim, Fernando)
- Installation of VXS crate and SSP modules complete, initial integration into DAQ underway by Sasha and Sergei.
- Simulation studies (Maria and Roman)
- Finalizing DIRC "as-build" geometry: support frames, etc. (Yunjie, Maria)
- Documentation of LUT algorithm by Maria
- Implementation of reconstruction in PID library underway (Justin)
- MAPMT testing (Bill and Andrew)
- Magnetic field test (delayed by access to laser setup)
- Update on ADC fitting procedure
- Commissioning plans
- Reminder: Addressing ERR review recommendations
- Recommendations pertaining to Fall 2018 DIRC commissioning should be addressed by August 20 (close of Hall D for beam)
- AOB
