Positioner on telescope

Focal plane/robots/parked fibers seen from top of positioner and from side port.

Cable and fiber routing for mounted hecto. along with upper to lower connection of cables.

Fiber support point old and new

Wavefront sensor unit and ADC unit connectors.

Corrector lens installed and ADC unit connected in cone.


Separation

Grant guiding spreader as cover is lifted.

Cover stored on clean plastic with plastic coated spacers to keep window off the floor.

More plastic is used over upper unit on lifting rig.


Guider Photos

Nelson inspecting the positioner's insides and how the fibers are routed.

Pictures of Guider #1, #2 and #3.

Home position for #3 guider, and a closer view.

Removed brake unit and its jaws.

Motor connector which gave us problems and how we fixed it with a new spliced connection.

Control electronics for the guiders - note permanent jumper on lower left.

Connector J65A with odd looking d socket which does not allow pin to seat as deeply as in other sockets.


Atmospheric Dispersion Corrector

Telescope mounting of ADC along with the ADC drive gear with its problem pin.

ADC motor and cabling visible with corrector on its transport cart. Releasing stuck gear and turning internal gear.

Hecto Spectrograph Benches

Spectrograph bench entering MMT in September 2002.

Light path for Spec bench::: From the fiber shoe and spec collimator mirror

then back past shoe and other grating on grating changer table to the active grating (covered) on its positioning table.

Through the corrector lens near the Fiber shoe to the camera mirror and CCD Dewar head.

Pumping station for evacuating dewars.

Storage areas

Basement of common building. First rack top, - second,- third,- bottom shelves. Second rack upper,- middle,- lower shelves.

Recent changes- Megacam Vacuum pump (L) relocated and stored below common building on rolling base.

To make space: 1) The handles were removed from large cover. ---- 2) Other circular pieces (L) were relocated near the door.

3) The threaded Rods (L) are between the cabinets on the right. ----- 4) The Pulizzis (L) are on top of the first rack.

[ the (L) is for a larger image]

Tom's cabinet in loft -top shelf has positioner & WFC items SBS& stepper items megacam, WFS and frame grabber items lighting spares


short term image storage Computers in rack, - Yoke computer rack, (rotated) - Computer monitors. - Robot computer monitors. - -
