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.
