PROSPECT: Detector Performance and Calibration*

The PROSPECT short-baseline reactor antineutrino experiment has performed measurements of the ²³⁵U reactor antineutrino spectrum, and searching for eV-scale sterile neutrinos.  The detector was designed specifically to manage the environmental background at the High Flux Isotope Reactor (HFIR) complex without overburden while maintaining the necessary energy resolution for the physics results. Extensive calibration of the detector has been performed with a variety of sources to characterize and validate the detector performance.  The detector calibration, performance, and background rejection capabilities will be discussed.
