Project management

• 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

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

• 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.

– 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 (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.

• 2.5
 m cut-off HgCdTe detector array,
• mounted in a cryostat with internal baffling,
• K dark 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.

• 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.

• 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).

Telescope mount
Alt-Azimuth or
Equatorial
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)

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.

• 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.

– e.g. design trade-offs.
• Lead Investigator will have responsibility for developing science teams & survey program.

• 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

• 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

• 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.

• 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.

• 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?

• 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.

• 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
