Abstract

The Optical Telescope Element (OTE) consists of a 6.6 m, all-reflective, three-mirror anastigmat. The 18-segment primary mirror (PM) presents unique and challenging assembly, integration and alignment requirements. To integrate and verify each of the Primary Mirror Segment Assemblies (PMSAs), an integrated network of laser trackers will be used in the Ambient Optical Assembly Stand (AOAS). The AOAS consists of an optical bench (OB) to support the JWST Optical Telescope Element (OTE), a personnel access platform structure (PAPS), an optics integration gantry system (OIGS), and a PMSA alignment and integration fixture (PAIF). The PAIF and OIGS are used to deliver; offload and precision align each PMSA segment and the aft optical subsystem (AOS) to their integration locations. This paper will introduce the functional design of this ground support equipment (GSE), illustrate the coordinate systems used for integration, and detail the integration processes.
