These pages describe our PEPSI Guiders project which has the goal of producing low cost CCD guider cameras for
the
Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) instrument built by Astrophysikalisches Institut Potsdam (AIP) for use on the Large Binocular Telescope (LBT).This project has been
sponsored by the AIP.
We have completed
fabrication and testing of ten cameras. These have system names PEPSI1 - PEPSI10. Each camera consists of Steward Observatory
thermoelectric cooled dewars, Magellan controller electronics repackaged
for our remote dewars, and ITL software.
All dewars contain e2v technologies, Inc. CCD57 detectors. Four of the CCDs have Shack-Hartman lenslets
mounted to their surface for use as wave front sensors. We installed
these lenslets (provided by AIP) as part of the project.
Five computers are
supplied, each running two cameras using two PCI interface cards per PC.
