Title: Deuterated-xylene (xylene-d 10 ; EJ301D): A new, improved deuterated liquid scintillator for neutron energy measurements without time-of-flight

Abstract

In conjunction with Eljen Technology, Inc. (Sweetwater,TX) we have designed, constructed, and evaluated a 3 in. x 3 in. deuterated-xylene organic liquid scintillator (C8D10; EJ301D) as a fast neutron detector. Similar to deuterated benzene (C6D6; NE230, BC537, and EJ315) this scintillator can provide good pulse-shape discrimination between neutrons and gamma rays, has good timing characteristics, and can provide a light spectrum with peaks corresponding to discrete neutron energy groups up to ca. 20 MeV. Unlike benzene-based detectors, deuterated xylene is less volatile, less toxic, is not known to be carci-nogenic, has a higher flashpoint, and hence is much safer for many applications. In addition EJ301D can provide slightly more light output and better PSD than deuterated-benzene scintillators. We show that, as with deuterated-benzene scintillators, the light-response spectra can be unfolded to provide useable neutron energy spectra without need for time-of-flight (ToF). An array of these detectors arranged at many angles close to a reaction target can be much more effective ( x 10 to x 100 or more) than an array of long-path ToF detectors which must utilize a narrowly-bunched and pulse-selected beam. As we demonstrate using a small Van de Graaff accelerator, measurements can thus be performed when amore »« less

Recent developments in deuterated scintillators for neutron measurements at low-energy accelerators

Journal Article Becchetti, F. D. ; Raymond, R. S. ; Torres-Isea, R. O. ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

Deuterated (2H-based) organic scintillators, unlike conventional -based scintillators can generate pulse-shape gated neutron energy spectra 1 to 30 MeV without need for time-of-flight (ToF). They are especially appropriate for measurements at high-intensity, low-energy accelerators where a pulsed beam is not available. Even when the latter is available, the loss in effective beam intensity combined with the need for suitable long-path ToF measurements can be very inefficient. In contrast, as we demonstrate, arrays of d- benzene scintillators (NE230, BC537, EJ315) and recently xylene-d10 (EJ301D) together with related digital signal processing (DSP) can provide highly efficient neutron energy measurements w/o n-ToF.

Characterization of Deuterated-xylene Scintillator as a Neutron Spectrometer

Journal Article Di Fulvio, Angela ; Becchetti, F. D. ; Raymond, R. S. ; ... - IEEE Transactions on Nuclear Science

We have experimentally characterized the neutron light output response functions of a deuterated-xylene scintillator for neutron energies lower than 10 MeV. We then used the response matrix to unfold the energy distribution of neutrons produced via several reactions, i.e. spontaneous fission, d(d,n)3He, 27Al(d,n)28Si, and 9Be(alpha,n)12C. Organic scintillators based on deuterated compounds show a fast response and good gamma-neutron discrimination capability, similar to proton-based scintillators. Deuterated scintillators can also effectively provide neutron spectra by unfolding measured data with the detector response matrix, without the need of time-of-flight. Deuteron recoils, produced by elastic collisions between deuterium and impinging neutrons, are preferentially forward-scattered.more »« less

Deuterated liquid scintillator (NE230) as a fast neutron detector for cold-fusion and other research

Conference Roberts, D A ; Becchetti, F D ; Ashktorab, K ; ... - IEEE Transactions on Nuclear Science (Institute of Electrical and Electronics Engineers); (United States)

Unlike conventional liquid scintillators (e.g. NE213) deuterated scintillators (NE230) can provide, without time-of-flight, usable neutron energy spectra for neutrons E[sub n] [ge] 1 MeV. In this paper, the authors assemble and calibrate several of these detectors and have used them in experiments searching for d + d fusion-neutron emission (E[sub n] [doteq] 2.5 MeV) in Pd + D[sub 2]O electrolysis and Ti + D[sub 2] adsorption at LN temperatures. The detectors yield direct fusion-neutron spectra and set limits in the Pd + D and Ti + D experiments of [lt] 7 [times] 10[sup [minus] 24] fusion n/s/dd pair and [lt]more »« less
Deuterated Liquid Scintillators: A New Tool for Neutron Measurements

Journal Article Ojaruega, M ; Becchetti, F D ; Torres-Isea, R ; ... - AIP Conference Proceedings

The response of large (4x6) deuterated liquid scintillators (up to 10 cm diameter by 15 cm) to neutrons in the energy range from 0.5 MeV to 20 MeV has been studied using several nuclear reactions, including d(d,n), and {sup 12}C(d,n){sup 13}N, at the University of Notre Dame FN tandem accelerator. The latter two reactions utilized 9 MeV and 16 MeV deuteron beams, including a pulsed beam that also permitted time-of-flight (ToF) measurements. Combining pulse-shape discrimination and (ToF) allows gating on specific neutron energy groups to determine the detector response to specific neutron energies.
