Abstract

Instruments & Instrumentation Science & Technology Technology
PROSPECT, the Precision Reactor Oscillation and SPECTrum experiment, is a short-baseline reactor antineutrino experiment designed to provide precision measurements of the U-235 product (nu) over bar (e) spectrum, utilizing an optically segmented 4-ton liquid scintillator detector. PROSPECT 's segmentation system, the optical grid, plays a central role in reconstructing the position and energy of (nu) over bar (e) interactions in the detector. This paper is the technical reference for this PROSPECT subsystem, describing its design, fabrication, quality assurance, transportation and assembly in detail. In addition, the dimensional, optical and mechanical characterizations of optical grid components and the assembled PROSPECT target are also presented. The technical information and characterizations detailed here will inform geometry-related inputs for PROSPECT physics analysis, and can guide a variety of future particle detection development efforts, such as those using optically reflecting materials or filament-based 3D printing.
