PALM-3000Background

The purpose of the work on the AO bench this winter is to accommodate the SWIFT and P1640 science instruments. This requires:

1. Moving the OAPs, FM2, TTM and DM to new positions for SWIFT focus

2. Making additions to the stimulus capability

3. Re-coating all the mirrors

4. Modifying the enclosure

PALM-3000Focus Change

Changing the location of science focus requires moving PHARO to a new location

• In order to have room for the SWIFT mounting pads, PHARO will be shifted forward in its support structure

• The FM3 location will be modified so that only PHARO’s position along the beam will change

PALM-3000Space Requirements

Because the new science instruments will use the entire width of the bench, the following are required in order to make space for the instruments:

1. Removable PHARO FM3 mount• Already in the machine shop

2. Removal of part of the current enclosure

• This requires a removable FM3 enclosure for PHARO

PALM-3000Other requirements

SWIFT has no X-Y adjustment with respect the to beam, so the stimulus must be remotely adjustable in X-Y. In order to complete this work before SWIFT arrives, it will be done in off the bench in parallel with the relay realignment.

This means that we will need an interim simulated-telescope-light source to use for the relay alignment while the stimulus package is being modified.
