NASA will fly x-ray microcalorimeters on several mission payloads scheduled within the next 5 years. New and improved blocking filters are urgently needed to realize the full potential and throughput of these missions. High transmission polyimide support mesh is being developed as an alternative to the nickel mesh currently used in blocking filter designs. Polyimide's composition affords high transparency to x-rays, especially above 3 keV. A new filter fabrication technique that simplifies assembly, eliminates adhesives from the filter field, and creates a stronger foil/mesh bond than epoxy, has also been demonstrated. In addition to support mesh, embedded resistive traces are being developed to provide deicing capability to actively restore filter performance in orbit. This report details the progress of this research to date.
