Abstract

The gamma-ray response of thin NE 905 6Li-glass scintillators is studied as a function of gamma-ray energy, scintillator thickness, and detector resolution. The probability for a gamma ray to simulate a neutron event is measured at three gamma-ray energies for three scintillator thicknesses. The feasibility of using coincidence information from electrons that diffuse out of the glass to reduce gamma-ray caused background is also studied.

    In recent years, glass materials have attracted much attention as scintillator and dosimeter materials because of their industrial merits such as reasonable fabrication cost, high transparency, large volume production capability, and easy shaping; therefore, glasses are prospective alternatives to single crystals and opaque ceramics for phosphor applications. There are few practical examples of glass materials for radiation measurement; however, silicate glass doped with 6Li and phosphate glass doped with Ag+ are commercially available as neutron scintillators and RPL materials, respectively [9,16,17]. To date, various glasses with luminescence centers have been proposed for radiation measurement [18–21].

    Among the glass scintillating materials, Ce-doped silicate glass (GS-20), which consists of a light element, has been utilized for neutron detection. It shows efficient emission due to the 5 d→4f transition of Ce3+, and the scintillation light yield is approximately 4000 photons/MeV [17]. Furthermore, glasses with heavy elements have attracted research attention for possible high-energy X-ray and gamma-ray detection applications.

    Glass materials have been studied for use in radiation detection in recent years because of several advantages, such as high transparency, reasonable cost, and flexibility in compositions [12–16]. A Ce3+-doped silicate glass with the glass host composition 34Li2O–5MgO–10Al2O3–51SiO2 is a well-known glass scintillator that shows intense luminescence derived from the 5d-4f transitions of Ce3+ [17]. It is applied in the detection of neutrons because the 6Li in silicate glasses has a large cross-section with neutrons.

    Recently, glass materials have attracted considerate attention for radiation measurements owing to their industrial advantages such as flexible glass compositions, low cost, large volume production capability and high transparency. In practical applications, 6Li-doped silicate glass and Ag+-doped phosphate glass have been utilized for neutron detection and individual radiation monitoring, respectively (Jensen and Czirr, 1983; Miyamoto et al., 2014). In recent years, radiation response characteristics of many glass materials doped with a luminescence center have been evaluated for scintillator and dosimeter applications.
