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 talk will introduce the functional
design of this ground support equipment (GSE), illustrate the
coordinate systems used for integration, and detail the integration
processes. |
