  10. ATST CoDR • Committee Matt Johns (Chair, Carnegie Obs.) Eli Atad (UK ATC) Torben Anderson (ESO) Eric Hansen (Gemini) Jacques Beckers (U. Chicago) Chris Mayer (Obs. Sci) Chas Cavedoni (Gemini) Michael Sheehan (Gemini) Ciro Del Vecchio (Arcetri) Larry Stepp (Gemini/NIO) Brent Ellerbroek (NIO) • Positive Comments on overall project • Assembled an outstanding project team • Healthy/constructive engineering-science interaction • Good design approach using existing concepts when possible • Project has addressed the concerns of previous reviews • Excellent documentation • Design strawman meets SRD

  11. ATST CODR • Recommendations for further design work • Some we are doing already • Some are planned for PDR • SRD • Review seeing/site ties • Requirements for Gregorian focus • Systems • Image quality error budget incorporating site data • Work out several observing scenarios • Optical • Throughput to Coude room • Further elaboration of alignment metrology

  12. ATST CoDR • Straylight • Need error budget • Some concern that we will not meet coronal specifications • AO • Better costing • Revisit DM position • Heat stop • Dome heating • Failure modes • Vibration • Primary Mirror Assembly • Careful specification - lack of experience with large off-axis mirrors • Lateral support • Mirror shake due to cooling system • Schedule issues

  13. ATST CoDR • Secondary Mirror and Transfer Optics • Coude lab interface (warm air in lab-cold air at telescope) • Trade study on materials • Coatings

  14. ATST CoDR • Science Working Group Report on CoDR also positive • CFD analysis has raised confidence in enclosure but, • Urge the project to complete the more realistic analysis that is planned • Include correlation between seeing and wind speed in the error budgets and MC simulations • Seeing effects along the Coude optical path • Complexity of thermal control, optimization to best seeing conditions • Interfaces between telescope components and instruments (e.g. Modulators and calibration optics) • Derotation at Gregorian Focus • Auxiliary light feed • Revisit height of telescope aperture after site (down) selection

  15. ATST CoDR • Reaction of Project to CoDR Review and Committee Report • Developing a formal response • But, initially ---

  16. CDR PDR 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 ATST TimelineWith and Without Long Lead Item Scientific and Technical Advisory Groups Select Site Schedule with Early Mirror Procurement Demonstrate High-Order AO system Technology Development Schedule with mirror Procurement at beginning of construction phase Concept & Design Mirror Procurement Mirror Procurement Construction Proposal Construction CoDR Integration Integration Operation

  17. ATST What’s Next • Construction Proposal • Cost – $161M, avoiding sticker shock • Broadening of Science Case • Impacts in other fields • Advocacy at NSF • AURA/SOC/Red Team Reviews? • Assume due 20 December • When does AURA need it • Non-NSF Funding – words but no $, cutting deals?, site • Instruments • How to include in the proposal? – Partners vs Competed vs International • If partners, establishing sound management structure • Completing the Site Survey • PS/ASWG Recommendation • Final decision: PI? + CoPI? + AURA + NSF + ……(congress?) • Review of Process and Choice? (AURA, ??)

  19. ATST What’s Next – NSO Where To • Operations • Cost estimate • International partners • NSO Structure and Operations

  20. Current Operating Costs

  21. ATST SOLIS GONG VSO 1 Facility Scientist 1 Telescope Scientist 5 – Instrument Scientists Adaptive Optics Vis and IR Polarimeters Vis and IR Filters Thermal IR 1 Data Scientist 2 entry level scientists 1 Facility Scientist 3 Instrument Scientists VSM FDP ISS 1 Data Scientist 2 Entry Level Scientists 1 Facility Scientist 1 Instrument Scientist 3 Data Scientist 2 Entry Level Scientist 1 Facility Scientist 1 Data Scientist 1 Entry Level Scientist Total - 27 10 7 7 3 Science Staff Support Levels

  22. Estimate with ATST • Current NSO $9.1M ($.66M from partners and revenue) • Roughly 20-25% higher based on increased manpower • $10.8M - $11.3M • 5% - 10% cost of ATST: $8M - $16M Based on SP+Tuc * 1.25 (no KPNO $) Add two postdocs Minimal science support This will probably go up for stand alone Minimal operation – higher during commissioning phase VSO?, Instrument Program?

  23. Deltas to NSF • ATST Mirror (hoped for congressional help) • Postdocs and Entry Level Staff • Deferred Maintenance/Upgrades • MP Control System • DST Camera’s and Controls • Sunspot • DST Dust Mitigation, Maintenance • Fire Doors • Fire Treatment • Housing • EPO

  24. Changes in Tenure Policy • Diversity as a major goal is important • Must insure centers can continue to meet mission and retain leadership role while achieving a more diverse staff • Must avoid defacto establishment of quota systems • Would like more time to discuss internally and with PPC • Center’s (who must implement the policy) need to discuss the proposed changes in some detail • Current policy allows for emphasis on service and innovation • Leadership and interaction with the community is and has been a major factor in tenure recommendations • AURA can make progress in diversity into a substantive performance evaluation factor • Automatic review • Express concern about process or candidate? (B-I-13) • Opens door for manipulation of tenure process by management council?

  25. NSO Plan to Increase Diversity • Early Mentoring – REU and SRA Programs • Growth in female representation • Minority recruitment still very low • Postdoctoral and Entry Level Recruitment • Irene GonzMalez-Hernandez (GONG) • Maud Langlois (ATST/AO) • Laura Allistaire (ATST/Filter) • Active Recruitment • Emphasis on diversity policy in job advertisements • Work with groups in professional societies • Target traditionally minority universities for recruitment • Promotions • Positive mentoring • Opportunity to lead

  26. Critical Decision Points • Demonstration of high-order adaptive optics on the DST and other meter class telescopes (2003)  • Demonstration of adaptive optics and technologies in the infrared on the McMath-Pierce Telescope (2003)  • Completion and commissioning of SOLIS (2003) Nov • Down selection to 2-3 ATST sites for further testing (2003) Oct • Submission of ATST construction proposal (2003) Dec • Select final ATST site (2004) • Funding of the ATST construction phase proposal (2006) • Decision on NSO headquarters location (2008) • Commissioning of the ATST (2010-12?) • SOLIS relocation (2010-12) • Relocation and consolidation of the NSO (2011-12)

  27. NSO in the ATST Era • Major new scientific capabilities • Ultra high resolution observations of magnetoconvection, solar activity, magnetic flux tubes, fibrils, ……… • Detailed maps of coronal structures and fields • Continuous vector magnetograms and observations of active region development • Precision Solar/Stellar observations • Subsurface and solar interior maps, far side imaging • Remote operations of ATST, SOLIS, GONG, Other? • Enhancement of the strong NSO program of instrument development • Consolidation of scientific staff • Co-location of NSO with a University
