Abstract:
The JPL large space simulator has recently undergone a major refurbishment to restore and enhance its capabilities to provide high fidelity space simulation. The nearly completed refurbishment has included upgrading the vacuum pumping system by replacing old oil diffusion pumps with new cryogenic and turbomolecular pumps; modernizing the entire control system to utilize computerized, distributed control technology; replacing the Xenon arc lamp power supplies with new upgraded units; refinishing the primary collimating mirror; and replacing the existing integrating lens unit and the fused quartz penetration window.
