SPT Illustrations

Therse relatively coarse illustrations were constructed for use in teleconferences discussing the internal layout of the South Pole Telescope. They are from a relatively early stage of its design and do not show much detail (none existed in the designs, let alone in actual matter, at the time).

The purpose of the teleconference series was to set up the rough positioning of the knowsn pieces of internal hardware so that they would not interfere with each other or the path of light throught he instrument.


Final Render

cryostat layout: right-oblique closeup view showing rays, filters, detectors
This is the final render (I) made of the SPT cryostat internal layout for the teleconference serias. It is from a solid model that included the cold stages, cryo-fridge, final lens, filter set, detector plane, and showed representative light rays through the optics. (56k)


Fourth Series (solid)

cryostat layout: right view
Right side view of the cryostat showing the rough outline of its exterior shape as well as the placement of detectors, filters, lens, and cold stages. Note the number of detector electronics cabinets (cyan) has been reduced a factor of two. (32k)

cryostat layout: right closeup view
Closeup of the same view. (44k)

cryostat layout: front view
Front view of cryostat showing secondary mirror. (44k)

cryostat layout: front-oblique view
Front oblique view. (40k)

cryostat layout: left-oblique view
Left oblique view. (44k)


Fourth Series (wireframe)

cryostat layout: right overview w/ optics + rays wireframe view
Right side wireframe view of cryostat showing mounting rail (representations) secondary mirror, lens, filters, detectors, cold stages, and some representative optical paths. Note the number of detector electronics cabinets (cyan) has been reduced a factor of two. (72k)
