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.
