External Insulation Systems for Cryogenic Storage Systems. Volume 1: Optical Properties of Kapton and Report of Process Variable Study

摘要

Investigations are conducted into the optical properties of the glass and Kapton substrate materials, and three variables were chosen: deposition rate, sputter gas pressure, and film contamination time. Substrate tests have shown that fabrication of an dielectric broadband reflector would require an extremely complex and expensive filter design.
