“…In the following section, we outline an apparatus that was designed to measure the thermal expansion of CFRP plates from 4 to 300 K. The measurement of CFRP thermal properties was done in collaboration with Glyndwr University, under the EU FP7-FISICA program. The goal of this study was to determine the feasibility of using CFRP in the design of lightweight, cryogenic mirrors for space interferometery 4 .…”

The next generation of space-borne instruments for far infrared astronomical spectroscopy will utilize large diameter, cryogenically cooled telescopes in order to achieve unprecedented sensitivities. Low background, ground-based cryogenic facilities are required for the cryogenic testing of materials, components and subsystems. The University of Lethbridge Test Facility Cryostat (TFC) is a large volume, closed cycle, 4 K cryogenic facility, developed for this purpose. This paper discusses the design and performance of the facility and associated metrology instrumentation, both internal and external to the TFC. Additionally, an apparatus for measuring the thermal and mechanical properties of carbon-fiber-reinforced polymers is presented.

“…As an example of the latter, we discuss in this paper the measurement of the temperature-dependent thermal expansion of carbon fiber reinforced polymers (CFRPs) in the 300 to 4 K range. This project formed part of a study of CFRP optical components manufactured by Glyndwr University as part of the FP7-FISICA program 4 .…”

“…For space telescopes in the MFIR wavelength regime, a technique using carbon fiber reinforced plastic (CFRP) mirrors shows promise to produce large, low CTE, and light mirrors [105]. In this method, a base substrate of resin and carbon fibers are laid down in a random orientation, resulting in a light and stiff structure.…”

Optics technology for large-aperture space telescopes: from fabrication to final acceptance tests

This review paper addresses topics of fabrication, testing, alignment, and as-built performance of reflective space optics for the next generation of telescopes across the x-ray to far-infrared spectrum. The technology presented in the manuscript represents the most promising methods to enable a next level of astronomical observation capabilities for space-based telescopes as motivated by the science community. While the technology to produce the proposed telescopes does not exist in its final form, the optics industry is making steady and impressive progress toward these goals across all disciplines. We hope that through sharing these developments in context of the science objectives, further connections and improvements are enabled to push the envelope of the technology.
