Abstract:

The results of preliminary studies using a spherical proof mass in the LISA mission are given. These include the acceleration disturbance performance, methods for controlling and calibrating a spinning sphere, system considerations, the possibility of using the spinning reference as a precision gyroscope to improve the attitude control, and a preliminary design with a spherical proof mass.

SPIE Conference on Astronomical Telescopes and Instrumentation

The SPIE conference was held on August 22 - 28, 2002 at the Hilton Waikoloa Village Hotel , Hawaii.

The LISA session program contains a list of all the LISA papers and authors presented at the conference. The paper referenced in this section was in Session III at 2:10 PM.

The Ground-Based Gravity-Wave Detectors session was held on the next day.

In addition to the LISA papers, probably the most interesting sessions were the ones on Large Ground-Based Telescopes and Future Giant Telescopes.

Session 14 in the ground-based program includes a paper on the first decade's science from the Keck telescope, and the session on future telescopes contains papers among others on:

The California Extremely Large Telescope (CELT), a 30-meter segmented mirror telescope. (See also a presentation on CELT by Jerry Nelson.)

The Overwhelming Large Telescope (OWL), a 100-meter segmented-mirror telescope being designed in Europe under the sponsorship of the European Southern Observatory (ESO).

The AURA Giant Segmented Mirror Telescope. A subpage of the AURA website has a list of the giant telescope projects.

A list of extra large telescope websites is also given on the Canadian XLT web page.

The Plenary Presentations of the conference also contain talks on the very large telescopes.
