摘要

BigBOSS is a proposed ground-based dark energy experiment to study baryon acoustic oscillations (BAO) and thegrowth of large scale structure. It consists of a fiber-fed multi-object spectrograph designed to be installed on the Mayall4-meter telescope at Kitt Peak, Arizona. BigBOSS includes an optical corrector assembly and 5000-fiber-positionerfocal plane assembly that replace the existing Mayall prime focus hardware. 40-meter long optical fiber bundles arerouted from the focal plane, through the telescope declination and right ascension pivots, to spectrographs in thethermally insulated FTS Laboratory, immediately adjacent to the telescope. Each of the ten spectrographs includes threeseparate spectral bands. The FTS Laboratory also houses support electronics, cooling, and vacuum equipment. Theprime focus assembly includes mounts for the existing Mayall f/8 secondary mirror to allow observations withCassegrain instruments. We describe the major elements of the BigBOSS instrument, plans for integrating with theTelescope, and proposed modifications and additions to existing Mayall facilities.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
