UofH Templeton Test Dewar Assembly Pictures

Status, July 20th, 2006

We have been supplied with a small test dewar, see pictures below, within which
to mount one of our 2 Mechanical Sample CCDs (Serial #02393-10-02).
Although these devices are designated as only Mech. Samples - they have been
tested and found to operate (will image) and are therefore suitable for this
phase of the SkyMapper Pan-STARRS Test Controller work.

This work is being undertaken to assist in getting the new Pan-STARRS test
controller up and running when it arrives at RSAA in about 2 months, with the
in the least amoount of time.

It was felt that this was an obvious way of getting us 'on the air' with
the new controller as we would be providing a dewar with a known working
SkyMapper CCD. This could then be sent back to UofH for them to then interface
to the new 16-channel Test Controller and hence provide a known working system
when it finally arrives back here at RSAA.

Although this has meant additional effort in providing some mechanical assembly
parts for our detector to fit to the dewar, and means supplying new internal
wiring and external cables for our controller, there are 2 CCD connectors on this
dewar as opposed to our units which have a single 55-way part, when finished
we will be in a position to provide a known working detector for UofH use.

Thanks to Peter Conroy for the design of the mechanical interface,
and to Col Vest who has done the mechanical fabrication.
Thanks also to Andre de Gans and Bernie Keys who are fabricating
the electronics parts for the inside and outside connectivity.
