Calibration of BC501A liquid scintillator cells with monochromatic neutron beams
نویسندگان
چکیده
The recoil proton energy response has been measured by exposing cylindrical cells, filled with BC501A BICRON liquid scintillator, to mono-energetic neutron reference fields. We determine the required calibration parameters and report the detailed procedures for the experimental data handling. A dedicated Montecarlo simulation has successfully been used to check the consistency of the experimental response functions and detection efficiency of our system. The results from this calibration is necessary for a detailed study of the neutron spectrum at the Gran Sasso Underground Laboratory, with a neutron detector made of 32 liquid scintillator cells, like those used during the calibration.

MEASUREMENT OF THE SCINTILLATION EFFICIENCY OF Na RECOILS IN NaI(Tl) DOWN TO 10 keV NUCLEAR RECOIL ENERGY RELEVANT TO DARK MATTER SEARCHES
We present preliminary results of measurements of the quenching factor for Na recoils in NaI(Tl) at room temperature, made at a dedicated neutron facility at the University of Sheffield. Measurements have been performed with a 2.45 MeV mono-energetic neutron generator in the energy range from 10 keV to 100 keV nuclear recoil energy. A BC501A liquid scintillator detector was used to tag neutrons...

In organic scintillators, the energy distribution of gamma rays and neutrons is indirectly measured by the pulse height distribution of light output produced through gamma ray and neutron reactions in the detectors. Accurate estimate of the interaction of gamma and neutrons in the detector and produce charged secondary particles and subsequent scintillation light produced in the calculation of ...
متن کاملDesign and Characterization of a Neutron Calibration Facility for the Study of sub-keV Nuclear Recoils
As part of an experimental effort to demonstrate sensitivity in a large-mass detector to the ultra-low energy recoils expected from coherent neutrino-nucleus elastic scattering, we have designed and built a highly monochromatic 24 keV neutron beam at the Kansas State University Triga Mark-II reactor. The beam characteristics were chosen so as to mimic the soft recoil energies expected from reac...

Background: The aim of this work was to establish how well gel dosimeters performed, as substitutes for brain tissue compared with standard phantom materials such as water, polymethyl-methacrylate (or PMMA), A150 plastic and TE- liquid phantom material for dosimetry of neutron beams in boron neutron capture therapy. Materials and Methods: Thermal neutron fluence, photon dose and epithermal neu...
