Attendees: Marc, Alex, Armin, Eliazar, Rebecca, Joe, Corey
- Check XRT stopper clearance - there is an interference with the rack - we have a few options to review
- Igor posted screenshots with options
- Alex will think on the options a bit
- Laser PRD coordination
- Dileep is out - Corey (and team) will be taking over. We'll set up a new meeting soon.
- baseline requirement discussions - touch base with other lead scientists - tomorrow 11-12
- not all experiments require the laser so maybe certain issues are not as critical?
- near hall vs far hall issues
- we are also ready to design laser out-coupling when laser team has details/requirements available
- Does the detector situation matter? beam tube size? this geometry is important...
- ideal hole diameter?
- Resend Z location info to M. Greenberg - help him figure out divergence etc. which will let us know what hole diameter we need...
- Facilities coordination - need to start discussing
- Detector Cooling
- Room Temperature control - can we control temperature locally at MODS table? easier? - first we need requirements
- do we have data? we have data at the exit window...moar data needed?
- Joe also has some data (tyler johnson has designed some environmental sensor boards)
- stability more important than accuracy of temp - can we control this operationally (letting things warm up and settle?)
- timing impact
- pointing impact
- JJ zooms/visit (27th) - questions about sticky slits
- Armin added LOC to functional diagram
- Elena is working on device list/mechanical schematic
- Alex will send us list of "old" names
- HAPPI database
- Alex will send us list of "old" names
- Detector - current plan? 2M +140k
- Meeting with Angelo today
- Angelo would like to be looped in on the plan as we inch forward
- even if we have 2M in 16M housing, cost increase should be minimal
- 4M minimum ~2angstrom resolution (but we need ~1.4)
- with 8M ~1.6A
- Number of modules shouldn't affect total depth
- Hole diameter?
- option: build an 16M shell with 4M modules?
- Alex will talk to David
- Angelo presentation?
- Costs? Options?
- 8M preferred - potential BCR (baseline change request)
- 2M may not be sufficient for most science cases
- Alex will create a summary of what we can achieve with each so we can do a cost/benefit analysis
- cost from Angelo?
- sparkpix better for smaller detector?
- need to talk about this a bit more
- Have we explored all funding sources?
- Alex might chat with Angelo to discuss options (speed/Area tradeoffs)
- Meeting with Angelo today
