WORKSHOP DETAILS:

THEME 1: THREE EDUCATION WORKSHOPS—29-30 March, 2006

Education Workshop #1--Wednesday, 29 March:

Institute for Scientists and Engineer Educators (ISEE): Identification of the most compelling intended outcomes

AGENDA (PDF)

The CfAO and the Center for Informal Learning and Schools (CILS) are currently engaged in activities aimed at enhancing teaching practices of graduate students, postdoctoral researchers, and other professionals. Both centers are now exploring the formation of the Institute for Scientist and Engineer Educators (ISEE) to formalize and institutionalize the most successful components of each center. A key element in moving forward is to identify outcomes that will be convincing to stakeholders, and potential stakeholders, that are essential to long term sustainability. The goal of this session will be to discuss the most compelling outcomes from the CfAO Professional Development Workshop and the CILS Science Fellows Program, which could become the planned outcomes for ISEE. For example, participants:

---Incorporated inquiry-based teaching into courses/programs
---Changed their teaching practices
---Gained valuable professional skills

Education Workshop #2--Thursday, 30 March, 9am-12:

Hawaiian Educational Initiatives

The CfAO has developed a range of educational programs in Hawaii, with a primary focus on advancing college students into technical career pathways related to observatories and the high tech industry. This session will focus on the engineering technology degree programs under development at Maui Community College, Hawaii Community College, and Kauai Community College, and how existing CfAO programs can complement these new degree programs. We will discuss the Akamai Internship Program, CfAO Short Courses, and new ideas for broadening student participation, particularly to increase participation of students from underrepresented groups. We will also explore mechanisms for facilitating involvement of scientists and engineers in course development and teaching.

Education Workshop #3 Thursday, 30 March:

1:00 - 2:00pm Restructuring and Planning Internships beyond CfAO

2:00 - 3:00pm Education meeting topics to be determined as needed, or as identified earlier in the day.

THEME 2: TWO ELTs WORKSHOPS--27-29 March, 2006

 

ELTs Workshop #1 Monday and Tuesday, 27-28 March: A 2-day Analysis, Modeling, and Simulation of AO for ELTs workshop (5'th annual)

 

Topics for AMS would closely follow last year's (See below). We will have new input on ELT system designs due to the TMT, GMT, and KPAO projects maturing. Speculation for the future generation of even more complicated and elegant AO systems is the topic of the VWAOA workshop.

Algorithms

-- Fast tomography algorithms ---Hardware implementation of wavefront reconstructors / controllers ---Incorporating site information (Cn2 or Na profile)

Laser guidestar constellations to maximize tomographic information per Watt AO relay optical design

---Internal calibration and alignment ---Accounting for aberration of LGS beam

---Models for thermal emissivity of the AO system and sky background

NGS Tip/Tilt/Focus sensing

---Sky coverage calculations

Wavefront sensing

---Linear WFS ---Spatial Filtering ---Pyramid Sensing ---LGS elongation ---Methods for accounting for rapid changes in the sodium layer profile ---Calibrating for Rayleigh backscatter

Astrometry/Photometry, Strehl stability and accuracy

---Deformable mirrors ---Stroke requirements ---Repeatability/linearity ---Woofer/tweeter offloading ---Influence function modeling, particularly for MEMS and adaptive secondaries

ELTs Workshop #2 Wednesday, 29 March: A new 1-day workshop on Visible Wavelength Adaptive Optics for Astronomy.

 

New technology developments could significantly break the cost curve of complex AO systems and could lead to the possibility of VWAO on 8-10 meter class telescopes in the near future. This workshop will be dedicated to exploring the possibilities, techniques, and needs for future generation AO systems, for example:
---Special problems in high order high speed wavefront sensing and correction, laser guidestar tomography, and sky coverage with natural tip/tilt/focus stars. ---Development of experiments to prove concepts and technologies needed for VWAO.

 

PLENARY SESSION: Wednesday, 29 March 6:00 pm

Distant Worlds: The Hunt for Planets around Other Stars

Steve Vogt
UCO/Lick Observatory
U.C. Santa Cruz

Abstract:

There are currently over 180 known extrasolar planets, the vast majority discovered through detection of periodic barycentric reflex motion of the planet's host star via high-precision Doppler radial velocity measurements. The California-Carnegie Extrasolar Planet Search Program is one such precision Doppler-based planet survey. It is currently monitoring over 1330 nearby F,G,K, and M stars for planets at 2-3 m/sec precision, and has contributed over 70% of the presently-known exoplanets. These extrasolar planetary systems display an unexpected diversity of orbital period, size, and eccentricity, and the emerging database is providing new insight into the origins and evolution of planetary systems. This talk will give a brief review of the California-Carnegie Exoplanet Search program, reviewing details of the detection method, and the current push toward detection of earth-mass rocky planets.

 

THEME 2: NEXT GENERATION KECK AO-- 30-31 March, 2006


Overall description and goals for this workshop:

The Keck Observatory is planning for its Next Generation AO System (NGAO).

The Keck AO Working Group has accordingly established four sub-committees to delineate the science case and to lay out the technical options and their expected performance. At the CfAO Spring Retreat March 30-31 '06, we will bring together members of the Technical and Science Instrument Sub-committee, the Solar System Science Sub-committee, the Galactic Science Sub-committee, and the Extragalactic Science Sub-committee, along with interested external experts.

Goals for the Workshop include the following:
Provide a description and update on the developing science cases;
Lay out the technical options for AO systems and instruments;
Describe simulation and modeling products needed to further advance the science cases;
Encourage a dialogue between the technical and science working group members, so that each may develop a better working understanding of the analysis tools and science requirements.

A proposal for the Keck Next Generation AO System is planned to be completed by June '06 for review by the Keck Science Steering Committee. Outcomes of the Workshop should materially aid proposal development.
