Paper Abstract

We present the first results from the University of Hawaii Institute for Astronomy project to develop largeformat optical CCD mosaics for the telescopes on Manna Kea. We have constructed two 4096 x 4096 mosaics: both are 2 x 2 arrays of 2-edge abuttable 2048 x 2048 15tm pixel imagers built by Loral Aeronutronics. The first mosaic is constructed using an abuttable package design yielding an array that can be assembled and disassembled using the bestavailable separatelytested quadrants. The second mosaic is formed by packaging a monolithic quad die consisting of four functioning 2048 x 2048 devices from a single wafer. In addition to the mechanical design of the focal plane and dewar we describe the system used to operate the CCDs including the programmable DSP-based CCD controller and our high-speed serial interface into the DSP port of a NeXT computer workstation. We present our initial x-ray and optical test results from the " monolithic mosaic" and our first data from the telescope. 1
