Abstract

This paper discusses the fabrication considerations and proposed testing concepts for a twelve meter, graphite-epoxy space truss that is being developed to provide structural support for the primary mirror system of the SpacE Laser ENErgy (SELENE) Beam Transmission Optical System (BTOS). A general description of the mirror support configuration is presented. Specific issues which are addressed include low-cost fabrication techniques utilized in the support structure. Later, a description of the dynamic testing program for the entire active primary mirror system is outlined.
