AST3-NIR camera for the AST3-3 telescope for the Kunlun Infrared Sky Survey (KISS)

1. AST3-NIR camera for the AST3-3 telescope for the Kunlun Infrared Sky Survey (KISS) Management and planning Julia Tims, Jon Lawrence 20 August 2015

2. Project Available Budget • ARC underfunded by $346k • AAO additional contribution of $350k from Department capital grant • Uni Syd increase contribution by $20k • TAMU contribution NOT contingent on work being conducted at TAMU • Swinburne contribution potentially >$0 (though problematic - for discussion)

3. Project Budget Status • NB: Budget estimate includes: • Pumping Station for Dome A • Option B Detector $ estimated • Glass optics $ estimated • Mech. BOM included • Descope (to 1k x 1k) is likely required: • USD (and GBP) exchange rate • Enhanced complexity of optics (cold stop) • Removal of Swinburne contribution ($175k) Uncertainties: • Optics procurement (through NIAOT?) • Cost of Selex (1 unit) and mosaic • Detector mount plate

4. Expenditure to date • No sign off on project plan • Currently no contract • Both issues need resolution asap

7. Outside Scope

8. Risks - programmatic • US export license for Dome A denied  move project to South Pole; • Australian export license for Dome A denied  move project to South Pole; • US export license for South Pole denied  re-evaluate; • Australian export license for South Pole denied  re-evaluate; • US export license for China denied  integration in Australia; • Deployment (South Pole) not approved by US NSF  project delayed. • No funds sourced to fill funding shortfall  de-scope to H1RG or H2RG engineering grade; • Project estimate too low  de-scope to H1RG or H2RG engineering grade; • Partners do not contribute full amount  de-scope to H1RG; • SUT do not obtain funding for laboratory  camera AIT at AAO, SUT instrument scientist to travel to AAO for assembly; • SUT instrument scientist position not filled  camera AIT at AAO using AAO personnel; • SUT instrument scientist does not overlap with detector delivery  SUT to extend position; • Detectors (long lead item) are delayed  project is delayed; • Scope creep  de-scope to H1RG; • Power module not funded  replace AST3-1 and AST3-2 or deploy to South Pole; • Deployment (Dome A) not approved by PRIC  project delayed;

9. Risks - technical • Vacuum hold time  design, analysis, and testing • Detector damaged during travel  mount design, packaging (vibration isolation) design • Optics misaligned during travel  mount design, packaging (vibration isolation) design • Selex detector performance  comprehensive system tests and detailed specification • Leach controller noise performance  comprehensive system tests and detailed specification • Controller or acquisition unit thermal issues  design of enclosure
