CLOSING REMARKS

We have recently tested the system and found that the camera performs well. The wheel mechanisms work properly cold and the system has good sensitivity. No ``ghost images" from multiple reflections off lenses or filters have been observed, where this was an issue of concern prior to the test. As a further test of the system, we mounted a 200 mm focal length ZnSe lens as a surrogate primary telescope mirror to provide an input image. Figure 6 was obtained using the f/15 camera optics, and a 9.9 $\mu $m filter looking out the window from our laboratory in Berkeley.

Many individuals have contributed to the LWIRC project, at SSL, LLNL, and Keck. In particular, we would like to recognize the SSL staff: G. Penegor, electrical engineer; P. Barale, computer engineer; R. Andersen, DSP software, RWA Enterprises; D. Zukauckas, technician; E. Lipman, graduate student and systems admin.; T. McDonald, machinist; and W. Fittelson; technician. R. Campbell and A. Conrad, of the Keck Observatory, have also been crucial members of the collaboration.

The LWIRC is supported under contract from CARA, the California Association for Research in Astronomy, a grant from the Campus-Laboratory Collaborations program of LLNL, and the SSL Director's Fund. This work was performed in part under the auspices of the U.S. Dept. of Energy by Lawrence Livermore National Laboratory under contract W-7405-ENG-48.
