Title: Neutrino Physics at Drexel

Abstract

Our primary goal is to improve the understanding of the properties and interactions of neutrinos. We are pursuing this by means of the DUNE long-baseline and PROSPECT short-baseline neutrino experiments. For DUNE, a neutrino beam from Fermilab will be detected at the SURF facility in South Dakota, with the aim of determining the neutrino mass hierarchy (the mass ordering of neutrino flavors), and a measurement or limit on CP-violation via neutrinos. Our near-term experimental goal is to improve the characterization of the neutrino beam by measurements of muons produced as a byproduct of neutrino beam generation, to quantify the beam composition and flux. The short-range neutrino program has the aim of using the HFIR reactor at Oak Ridge as a neutrino source, with a detector placed nearby to find if there are short-distance oscillations to sterile neutrino flavors, and to resolve the 'reactor neutrino spectral anomaly' which has shown up as an unexplained 'bump' in the neutrino energy spectrum in recent experiments.

  • Final technical report for work performed on the reactor neutrino experiments (Double Chooz, PROSPECT) and DUNE beamline monitoring.
  • The goals of this research are the experimental testing of fundamental theories of physics beyond the standard model and the exploration of cosmic phenomena through the techniques of particle physics. We are working on the MACRO experiment, which employs a large-area underground detector to search fore grand unification magnetic monopoles and dark matter candidates and to study cosmic ray muons as well as low- and high-energy neutrinos; the Chooz experiment to search for reactor neutrino oscillations at a distance of 1 km from the source; a new proposal (the Perry experiment) to construct a one-kiloton liquid scintillator in the Fairport,more » Ohio underground facility IMB to study neutrino oscillations with a 13 km baseline; and development of technology for improved liquid scintillators and for very-low-background materials in support of the MACRO and Perry experiments and for new solar neutrino experiments.« less
  • A visit was made to the Drexel Heritage Facility No. 60, Morganton, North Carolina for the purpose of observing the processes and associated controls for veneering wood panels using heated platen presses. Specific concern was expressed about controlling formaldehyde emissions. At this specific site, veneered panels were produced by both the hot press and the radiofrequency (R/F) press methods. A canopy hood exhausted through a duct to a roof fan was installed about 4 feet above the inspection platform of each feed through press. A small canopy hood covers a small mixer on the main floor. Auxiliary fans were placedmore » throughout the facility. A few ceiling vents were noted, but the only makeup air was the filtered air returned from the dust collection system in winter. Each canopy hood captured only part of the emissions which rose from the platform. The volumetric airflow rate was not sufficient to capture vapors much beyond the boundary of the large canopy opening. Partial shift time weighted average formaldehyde concentrations were all less than 0.5 parts per million (ppm), except around the large R/F press where some peak concentrations were 3 ppm. The author concludes that this facility offers a unique opportunity to study the effectiveness of a canopy hood over an unloading platform.« less
  • This document summarizes background information and presents results related to temperature measurements in the Advanced Test Reactor (ATR) National Scientific User Facility (NSUF) Drexel University Project 31091 irradiation. The objective of this test was to assess the radiation performance of new ceramic materials for advanced reactor applications. Accordingly, irradiations of transition metal carbides and nitrides were performed using the Hydraulic Shuttle Irradiation System (HSIS) in the B-7 position and in static capsules inserted into the A-3 and East Flux Trap Position 5 locations of the ATR.
