The Workshop on Neutrino Science and Applications at HFIR will held at the Oak Ridge National Laboratory to explore opportunities provided by the unique High Flux Isotope Reactor (HFIR) facility (see attached Fact Sheet) to host a world-leading neutrino science experimental program over the next two decades that matches the spirit and utility of its sister laboratory at the Spallation Neutron Source (SNS) at ORNL, Neutrino Alley.  Many physics topics accessible at a short distance from an intense and well quantified source of MeV-scale electron antineutrinos like HFIR were described in a recent whitepaperThis workshop seeks participation from a broad community to explore two goals:

  1. identifying fundamental science topics that could be pursued at HFIR in the near-term with the current facility configuration and 
  2. identifying facility upgrades, e.g. to shielding and overburden, that could unlock additional scientific opportunities in the medium-to-long term. 

HFIR recently hosted the PROSPECT experiment which, while carrying out its physics program, quantified HFIR background conditions, demonstrated technology for on-surface rare event searches, and established the ability of HFIR facilities to support fundamental neutrino science. The workshop will provide a forum for communicating existing capabilities and knowledge for exploring how they can be leveraged to benefit other measurements

 

Within the existing HFIR facility, PROSPECT’s shielding platform and supporting infrastructure are already approved for operation within HFIR and will support the upgraded multi-ton PROSPECT-II experiment. This resource could also potentially host other new experiments with similar shielding needs. For instrument concepts requiring less shielding, the HFIR experiment hall may support simultaneous operation of multiple efforts.  We invite speakers to present ideas for new use cases, experiments or R&D efforts using this existing HFIR infrastructure

 

A planned long HFIR outage beginning in 2028 presents an opportunity to implement facility modifications that could include enhanced shielding capacity, modifications to floor/head space and floor loading, and more. Thus, we also solicit ideas for new efforts that may require substantial HFIR facility enhancements.  A White Paper summarizing the outcomes of this workshop can provide critical HEP input to ongoing HFIR facility upgrade discussions within the ORNL, BES, and NP communities.
