Meeting with POMO
Date: Sep 22, 2014 (Mon)
Time: 10 am (7:00am PDT departure from Cahill)
Location: Palomar conference room and P48 ... TBC
Participation
Attending at from POMO: Dan McKenna, John Henning, Bruce Baker, Kevin Rykoski, Drew Roderick, Carl Dunscombe |
Attending from Campus: Richard Dekany, Roger Smith, Paul Gardner, Justin Belicki |
Agenda
- Intro to ZTF - Rich Dekany (45 minutes)
- Telescope Requirements - Roger Smith (30 minutes)
- Open Discussion on how requirements translate to the physical work on the telescope (1-2 hours)
- Lunch (continued discussion during lunch)
- Resources/Scheduling/Management Structure (1 hr)
Minutes
- Need to coordinate on UPS selection for instruments; coolers need UPS too.
- Divide improvements up and implement as separate projects: start with down time concentrated in rainy winter period. Many tasks can proceed with daytime work which we would like to start well before commissioning.
- Add field rotation to IRD: control with polar axis (mis)alignment or hexapod?
- Roger (and Richard Walters) test whether dust on corrector can be measured by direct illumination of corrector when looking at sky (e.g. with flat field LEDs).
- Need counterweight for telescope shake test.
- Need to calculate mass distribution and start on new counterweights.
- Paul to select suitable low outgassing black paint.
- Dan will select differential pressure sensor for wind and install. Roger will send wind speed calculation to Dan.
- Let's run Archon CCD controller in dome to determine if there is noise pickup in our passband.
- Dome drive: begin after Aluminizing (Dec)
- Windscreen: may order new blinds and possibly better encoders. POMO will test to decide what is needed. Currently bang-bang may needs speed controlled motor and better encoder. Rich, proposes delaying work on this until tests indicate that its needed: motor torque, differential wind pressure, telescope shake tests.
- Done to go wireless to allow the back side slip rings to be decommissioned.
- Need one spare dome truck to serve 60" and 48".
- Need to add blind pointing specs to IRD.
