Rad Facilities

Our dedicated Rad IDEAS group lab and office space at UT-Knoxville consists of a few thousand square feet, comprising an entire wing on the top floor of Ferris Hall (rooms 507-509).  In this lab, we have a host of gamma, neutron, and alpha sources; bench top-level radiation sensor and optical components; single and multichannel nuclear electronic modules; data acquisition electronics; oscilloscopes; and high performance multicore workstations for data acquisition, processing, and simulations.  Highlights include

  • Many channels of 2 GHz bandwidth, 8 GSa/s, 10 bit digitizers for fast timing measurements
  • Multichannel VME data acquisition system for shaping, time pickoff, and energy pickoff
  • Multichannel digitizer and firmware shapers for high energy resolution semiconductor detector readout
  • Philips digital silicon photomultiplier evaluation kit, including coincidence circuitry
  • Intensified Charge Coupled Device with optical lens for very high resolution neutron radiography
  • Fast pulse Picoquant laser (70 ps, 375 nm)  for characterization of fast photosensors
  • Multicore workstation for running ZEMAX optical transport software
  • Two microchannel plate photomultiplier tube arrays and many high speed 2″ and 1″ photomultiplier tubes

The other main laboratory spaces used by my group include

  • The UTK Scintillation Materials Research Center, including a 24 zone furnace for crystal growth that belongs to us
  • UTK Microprocessing Research Facility
  • Facilities at the ORNL Center for Radiation Detection Materials and Systems, including furnaces for glass fabrication and equipment for characterizing optical and physical properties of glasses
  • Laboratory facilities and equipment of the ORNL Nuclear Security and Isotope Technology Division, including
    • A proof-of-concept dual neutron and gamma ray imaging trailer system, called Dual Detection-Localization-Imaging (DLI), consisting of large volumes of NaI detectors and organic scintillators built into a coded aperture imaging array
    • Access to Associated Particle Imaging (API) Deuterium-Tritium (D-T) neutron generators and Cf-252 ionization chambers
    • Access to the Nuclear Materials Identification Systems (NMIS), including laboratory and fieldable versions
    • A neutron measurements background trailer, equipped with a large volume of liquid scintillator and weather station
    • Portable neutron coded aperture imaging systems (Paul Hausladen, PI)
    • Gamma ray coded aperture imaging systems (Klaus Ziock, PI)
    • Access to a safeguards laboratory where uranium standards are stored
    • Access to a portal monitoring facility
  • Neutron science beamlines at the High Flux Isotope Reactor and the Spallation Neutron Source (and associated development and testing laboratories)
  • Linear accelerators at the Idaho Accelerator Center; incidentally, a new Linac facility is planned for our new UTK engineering complex
