---++Meeting with POMO Date: Sep 22, 2014 (Mon)<br> Time: 10 am (7:00am PDT departure from Cahill)<br> Location: Palomar conference room and P48 ... TBC<br> *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. -- Main.RogerSmith - 20 Sep 2014
