Kunlun Infrared Sky Survey

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

Project Aims

Primary aims of this project are to:• conduct a deep high-cadence wide-field Kdark

infrared sky survey (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.

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.

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

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.

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.

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.

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).

TelescopeTelescope mount

Alt-Azimuth orEquatorial

Telescope 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)

Outside ScopeFollowing 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.

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.

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

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,

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

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.

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.

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?

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.

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 needsNew policies• Lifan will consider a policy to support instrument builders.Next meetings• SCAR AAA Hawaii August• Nanjing Meeting 2015 end
