Telescope:

Note: WM Keck DSM team is working on a Solidworks 3D Model of the telescope based on best available documentation. This model will be suitable for preliminary design for NGAO, however all critical dimensions will need to be field verified. Currently the modelling effort has been funded for the left Nasmyth Deck and the Top End.

The following is a collection of documents that can be used for conceptual design only

Telescope Focus:

• Keck AO with telescope focus - sketches

The maximum loading of the platform from our telescope structural designer, Stefan Medwadowski, is a live load of 40 psf with a total instrument load of 22,000 lbs. This is documented in the following attached document: * Investigation of the Right Nasmyth Platform of the Keck II Telescope by Medwadowski, 3/26/2001

Services on the telescope:

*Jib Crane 5 ton with reach from Dome wall to begining on the Nasmyth Platform *Shuttle Crane 5 ton with reach covering the entire Nasmyth Platform *Glycol for instrument cooling. System is currently near maximum load and additional loading would most likely require an upgrade. *Pressurized air from machinery room. Not instrument quality.
