Recap of Recent Events and Schedule for Next 3
Months

Summary

• It has now been 5 1/2 mos. since the camera
  kick-off meeting.
• There has been a lot of progress on the
  organizational and political side (see following
  slides).
• DOE involvement is now fairly secure. DOE-OS
  still needs to find the money (especially in
  FY05) but this is being worked.
• It is now time to do some real work. To keep
  this project on-track, we want to push for CD-0
  early in the Fall of 04 (see Althouse
  presentation following). This will require a
  much higher level of technical specification than
  currently exists for all camera subsystems.

Events Since Kick-Off

• NSF DD Proposal formally submitted January 04.
  It is currently still out for review.
• Presentation to SAGENAP made in April 04. Letter
  of Intent for DOE participation included in the
  presentation. First presentation of a camera
  budget through construction.
• Physics of the Universe report released by OSTP
  in April 04. Highlights LSST as a joint NSF/DOE
  project with beginning of operations in 2012.
• Quantum Universe report released by HEPAP in May
  04. Includes LSST as HEP project addressing dark
  matter and dark energy.
• First presentation on DOE involvement made at
  LSSTC Board Meeting in May 04.
• Science Requirements Meeting held in Tucson in
  May 04.
• Data Management kick-off meeting held in Tucson
  in May 04.

What are the next steps?

• SAGENAP will issue a recommendation, hopefully
  endorsing DOE involvement in LSST. Comments from
  individual committee members suggest that the
  report will be very favorable.
• We will probably then be asked to make a
  presentation to HEPAP, apprising them about the
  project.
• Formal approval will have to come from P5. My
  guess is that this will occur next year, probably
  in response to a formal proposal from us to DOE.
• We are hoping to get a CD-0 review in October
  04. This will give the project a formal status
  with the agency. Our insides sources tell us
  that LSST is viewed very favorably at DOE, but
  that finding the money for it will be a challenge
  in the current budget climate.

Key Challenges Over the Next 3 Months

• Optical design must be frozen by August. There
  are two aspects to this
• Long vs Short design decision. This has a
  big effect on the camera location and its
  mounting to the telescope.
• Definition of FOV. Affects the size of the array
  (linear) as well as the lenses (faster than
  linear). We need to understand the cost/schedule
  and complexity implications.
• Other outstanding zeroth order issues requiring
  near-term resolution
• Camera rotation requirements. We need to
  understand the implications and limitations.
• Filter exchange mechanism. Internal or external
  to the camera can? Number of filters mounted on
  the camera at any given time? Filter
  refurbishability?
• Wave-front sensing implementation. Dedicated
  sensors? How many? Where? Read-out
  requirements?
