  3. Kunlun Infrared Sky Survey

  4. Document Scope • project definition plan for AST3-NIR Antarctic instrument project, • funded via a successful ARC LIEF grant • includes instrument high level aims & objectives, • key project personnel, • the proposed concept, • budget, and schedule, • assessment of key risks at initialisation phase

  5. Project Aims Primary aims of this project are to: • conduct a deep high-cadence wide-field Kdark infrared skysurvey (KISS) from Antarctica; • enhance Australia/China/US collaboration in Antarctic astronomy; • gain knowledge on operation of & procurement for IR detector arrays to be used in Antarctica.

  6. Project Objectives • Design & build a wide-field K-band imager for AST3-NIR telescope • AST3-NIR telescope is designed & built by NAOIT; • Integrate & interface imager with AST3-NIR telescope • location for integration to be determined, • possibly U Tas in Hobart per John Dickey & Andrew Cole • Support commissioning activities (in-person and/or remotely) for the AST3-NIR telescope + instrument in Antarctica • at Dome A, South Pole, or Dome C.

  7. KISS LIEF proposal Investigators • Jeremy Mould (SUT) as Lead Investigator • Karl Glazebrook (SUT) as Chief Investigator • Michael Ashley (UNSW) as Chief Investigator • Michael Burton (UNSW) as Chief Investigator • Lifan Wang (TAMU) as Partner Investigator • Ji Yang (PMO) as Partner Investigator • Anna Moore (Caltech) as Partner Investigator • Jon Lawrence (AAO) as Partner Investigator • Peter Tuthill (USyd) as Chief Investigator • Mike Ireland (ANU) as Chief Investigator.

  8. Key instrument project roles • Jeremy Mould (SUT) as Lead Investigator • Jon Lawrence (AAO) as Project Leader • Julia Tims (AAO) as Project Manager • Jessica Zheng (AAO) as Instrument Scientist • Nic Bingham (AAO) as Control System Engineer • Michael Ashley (UNSW) as Control System Lead • Xiangyan Yuan (NIAOT) as Telescope Lead Scientist

  9. Ownership • “The instrument developed and all materials procured for the instrument project will be owned by Swinburne and made available on-loan to the project team for the duration of the project” • i.e. to the end of the KISS survey phase • this is of no consequence for the science • and doesn’t apply to the telescope or its other attachments, such as the data system

  10. Science case Science case (more detail in LIEF text) includes: • supernovae, • exo-planets, • variable stars, • AGN reverberation mapping, • gamma-ray-bursts, • young stellar objects, • young massive stars, • cosmic infrared background.

  11. Concept Baseline instrument concept consists of • 2.5 m cut-off HgCdTe detector array, • mounted in a cryostat with internal baffling, • Kdark filter and optically powered window • camera mounts to flange on telescope providing focal control. • Narcissus mirrors mounted on telescope structure are used to reduce thermal emission • rather than a cold stop within the cryostat. • instrument includes control system • interfaces with AST3 telescope & PLATO Supervisor computer.

  12. Detector Array & Cryo System • Supplier of detector array • Baseline is Teledyne; • Also to be explored is Selex ES, a European company who may be offer an alternative without ITAR restrictions. • Array size and configuration • Baseline and preferred option is science grade H2RG (2k x 2k); • De-scope options include engineering grade H2RG (with contiguous 1k x 1k region), and science grade H1RG (1k x 1k array). • Detector and cryo system supplier • Baseline is Teledyne+GL Scientific to supply detector with detector mounting plate and SIDECAR ASIC focal plane electronics • AAO to design cryostat body, cooling & vacuum system, baffling, window mount, & filter holder • Alternative #1 is Teledyne+GL Scientific to supply complete winterised detector/cryo/controller system • Other alternatives to be explored.

  13. Telescope InterfaceTelescope configuration • AST3-3 is a clone of the AST3-2 telescope but with a folded Nasmyth focus • this telescope is currently in the construction phase; • AST3-4 Cassegrain-focus infrared-optimised telescope with the same mirror diameter as AST3-2 (i.e. 0.68 m). • likely to have superior performance for AST3-NIR camera • currently unfunded with a longer lead time. A preliminary optical design exists for this telescope • A larger telescope with 1 m diameter (unfunded).

  14. TelescopeTelescope mount Alt-Azimuth orEquatorialTelescope location • Preferred option is Chinese Kunlun station at Dome A; • Alternatives (due to ITAR restrictions) are US Amundsen-Scott South Pole station or French-Italian Dome C station. • Telescope/instrument integration • Preferred option would be to integrate & test instrument with telescope in China, but this is unlikely due to ITAR • Camera integration may be at Swinburne (pending lab space) • Camera/telescope integration may be at U Tas in Hobart (lab space available)

  15. Outside Scope Following activities not within scope of project but are essential: • AST3-NIR telescope & telescope control system: To be provided by NIAOT. • Deployment & logistics to & in Antarctica: To be provided by PRIC or NSF OPP. • PLATO power supply: existing PLATO-A power supply module does not provide sufficient power for AST3-1, AST3-2, and AST3-NIR & instrumentation. • new module is required – likely dedicated to AST3-NIR+instrument. • this is currently not funded. • Operations: Observatory and telescope operations are not included within project scope. To be provided by NAIOT+UNSW. • Survey program: Development and management of science cases & observing program to be provided by science team(s) coordinated by Lead Investigator. • See preliminary KISS plan for M.Burton, M.Ashley and team roles • Data pipeline: Under this project a functioning software/control system will be provided with limited capability to transfer data or for image analysis. • A more sophisticated on-site data reduction pipeline is not currently assigned or funded. Capability to create source catalogs on site is required. • Data archive is allocated to ANU according to the LIEF.

  16. Project subsystems (WBS) • Systems & Management: Project management, systems engineering and instrument requirements management • Interfaces: Development of interface specifications and drawings for telescope, detector, and electronics/control systems • Detector & Controller: Design & procurement for detector & detector controller • Cryostat System: Design & procurement for cryostat body and cryo-controller; • Control System: Design, procurement, & assembly for instrument controller. • Software: Development and testing of low level control software and high level instrument control and interface software; • AIT: Camera sub-system integration & testing, and integration of camera with telescope to occur within Australia. • If integration in China is allowed, additional travel funding will be required.

  18. Management • AAO’s Project Leader and Project Manager will manage the camera project. • Lead Investigator’s role will be to provide sign-off on the Instrument Requirements and take responsibility for all high-level decisions • e.g. design trade-offs. • Lead Investigator will have responsibility for developing science teams & survey program.

  19. Project Reviews • Consistent with similar sized instrument projects at AAO, there will be no formal external reviews. • There will be a series of internal reviews • as given in the scheduled milestones: • Requirements Review, • Final Design Review, • SAIL Readiness Review, • Camera Pre-Delivery Review. • These reviews will involve a subset of: • LIEF team • AAO/SUT/UNSW project team • representatives from the NIAOT telescope team.

  20. Work Distribution Option A • In this model, AAO will be responsible for overall management and systems engineering of project and for the design and procurement of all components. • AAO will be responsible for assembly and testing of instrument control electronics and software • some fraction possibly subcontracted to UNSW • SUT will be responsible for AIT of detector and cryostat subsystem, & overall instrument system integration & test • These tasks will occur at SUT laboratories • employment of a new SUT detector engineer. • AAO and SUT will both contribute to the telescope integration and commissioning support activities

  21. Work Distribution Option B • In this model, all available funds ($1,175k) will be transferred to the AAO • responsible for all aspects of camera project, including management, systems engineering, design and procurement, & assembly & testing. • NB: Some fraction of the control system may be sub-contracted to UNSW.

  22. Contracts • MIA will distribute all project funds to SUT. • After MIA signed, subcontract will be prepared to arrange for transfer of funds between SUT & AAO • subcontract specifies detailed Statement of Work • based on an AAO template • previously used with other Australian unis for LIEF

  23. Preliminary Risk Assessment (in order) • US export license for Dome A denied  move to South Pole • Aust. export license for Dome A denied  move project to SP • 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 • No funds to fill funding shortfall  de-scope to H1RG • Project estimate too low  de-scope to H1RG • No SUT funding for lab  camera AIT at AAO, SUT engineer to AAO for assembly; • No SUT detector engineer  camera AIT at AAO using AAO personnel • SUT detector engineer not well qualified  camera AIT at AAO • No SUT detector engineer overlap with detector delivery  SUT to extend position; • Detectors (long lead item) are delayed  project is delayed; • Partners do not contribute full amount  de-scope to H1RG; • 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; • Deployment (South Pole) not approved by US NSF  project delayed

  29. Management • Jeremy Mould will make an org chart • Jessica Zheng will make an ETC • Michael Burton will create and maintain a set of science requirements • Jeremy & Lifan will consider the composition of an External Advisory Committee

  30. Telescope • We agreed that the baseline plan is to design mods to AST3-3 to meet the science reqs, not to propose AST3-4. • Jessica & Haiping will work on baffle design to meet the science requirements. • This is preferred to changing the speed of the telescope beam, or changing the bent Cassegrain design. • They will also specify the mirror coatings (gold or …..). Environment control • Jon, Michael, Xiangyan, Vlad will develop a thermal model of telescope. • Some of the resources to maintain optical transmission & thermal equilibrium are CaH absorber, ITO, waste heat. • AST3 only monitors temp of encoder not tube but some Mohe data exist.

  31. System requirements • Science = Jessica • Transport = PRIC • Operation, includes telescope, services, ops, environment, work. • Sunpower cryocooler will be used. • To handle outgassing of plastics, getter will be used. • Vlad, Xiangyan and Haikun will study the focus mechanism to avoid duplication if possible. • Jon, Xiangyan and Jessica will study other optics issues, such as the edge treatment of the fold mirror. Control system • Michael talked about power system redundancy, power down modes, transients (ESD & EOS), testing manufacturers’ specs, maximizing software control.

  32. Detector • ANU currently has most Teledyne experience. • Cognizant engineer to visit AAO • Jeremy Mould and Nick Suntzeff will develop a calibration strategy. (Is a shutter required?) Computers • Can we develop hardware and software standards for the project? Shihai Yang , Xiaoyan Li and Michael will review the computer architecture of AST3-2. Can it be improved? Should we use new low power processors and He filled disks?

  33. Interface Control Document • TBD • Xiangyan will develop a schedule for the NIAOT work and compare with the schedule for AAO work. Jeremy will add a software review to the team plan. When is the science project complete? Backup deployment plans • Lifan will write an NSF OPP proposal. • Jeremy will develop an iPeV proposal. Data Management • Michael Ireland will develop a technical data management plan. This does not include any changes to the AST3 collaboration’s data access policies. There will be data releases to the community.

  34. Filter • Peter Tuthill will study the impact of changing Kdark’s Delta lambda from 0.18 um. • There is no filter wheel in the baseline design. Enabling data • Jeremy will list our needs New policies • Lifan will consider a policy to support instrument builders. Next meetings • SCAR AAA Hawaii August • Nanjing Meeting 2015 end
