CHELSI: A PORTABLE NEUTRON SPECTROMETER FOR THE 20- 800 MEV REGION
T.D. McLean, R.H. Olsher, L.L. Romero, L.H. Miles, R.T.Devine, A. Fallu-Labruyere, P. Grudberg
(PDF format, 491 KB in size)

ABSTRACT: CHELSI is a CsI-based portable spectrometer being developed at Los Alamos National Laboratory for use in highenergy neutron fields. Based on the inherent pulse shape discrimination properties of CsI(Tl), the instrument flags charged particle events produced via neutron-induced spallation events. Scintillation events are processed in real time using digital signal processing and a conservative estimate of neutron dose rate is made based on the charged particle energy distribution. A more accurate dose estimate can be made by unfolding the 2D charged particle versus pulse height distribution to reveal the incident neutron spectrum from which dose is readily obtained. A prototype probe has been assembled and data collected in quasi-monoenergetic fields at the The Svedberg Laboratory (TSL) in Uppsala as well as at the Los Alamos Neutron Science Center (LANSCE). Preliminary efforts at deconvoluting the shape/energy data using empirical response functions derived from time-of-flight measurements are described.

Towards Digital Gamma-Ray and Particle Spectroscopy
W. Skulski, M.Momayezi, B.Hubbard-Nelson, P.Grudberg, J.Harris, W.Warburton
(PDF format, 237 KB, 10/4/1999)

Abstract: Digital spectroscopy is an experimental technique for directly processing detector signals without analog signal shaping. Digital spectrometers capture the detailed shape of preamplifier signals with high speed ADCs, and then process captured waveforms in real time with field--programmable gate arrays and digital signal processors, that perform digitally all essential data processing functions, including precise energy measurement and event timing, ballistic deficit correction, pulse shape analysis, and time stamping the output data for offline analysis. Applications of this novel technology include position sensitive gamma-ray spectroscopy with arrays of Ge detectors and high-speed particle emission spectroscopy. In both applications digital spectrometers process signals from semiconductor detectors in order to measure the interaction energy, time, and location within the detector volume. Excellent energy resolution and essentially zero dead time can be easily obtained with XIA digital spectrometer devices, even when time separation between consecutive events in a decay chain is shorter than 1 microsecond. These and other applications of digital spectroscopy are at the frontier of experimental nuclear chemistry and nuclear physics.

Digital Spectrometer For Automating XAS Data Collection
W.K. Warburton, B. Hubbard & C. Zhou
(PDF format, 387 KB, 1999)

Abstract: Energy dispersive x-ray fluorescence is a well developed experimental technique for studying both the atomic composition of unknowns (fluorescence analysis) and the atomic structure of matter at the atomic level (EXAFS). In order to assist researchers interested in extending their capabilities with multi-element detectors, X-ray Instrumentation Associates recently introduced the DXP- 4C which contains 4 complete channels - amplifier through MCA - of electronics in a single width CAMAC module. Using these new electronics can improve throughput considerably, compared to either an conventional analog SCA system or a multiplexed MCA system, while also allowing complete computer control of all parameters. This new module allows even detector arrays with large numbers of elements to be instrumented very compactly. The paper describes both the architecture of the DXP electronics and its various applications.

Time Resolved XAS Data Collection With an XIA DXP-4T Spectrometer
W.K. Warburton, B. Hubbard, C. Zhou & C. Booth
(PDF format, 82 KB, 1999)

Abstract: Time resolved experiments can be divided into two categories: single shot experiments and cyclically repetitive experiments. The former can only be carried out once per sample, the experiment typically either destroys the sample or transforms it into a new state from which it is difficult to return to the original. Chemical reactions often fall into this category. Cyclically repetitive experiments, on the other hand, are carried out on materials can be returned to their starting state, allowing the experiment to be repeated as often as necessary to collect data of interest. Many mechanical, electrical, and phase equilibrium experiments fall into this category. Biological systems may fall into either category. The DXP-4T, a recently introduced, modified version of the DXP-4C Digital X-ray Spectrometer, can be applied to XAS studies of either class of cyclically repetitive experiment. The paper discusses time-resolved XAS research opportunities with XIA's DXP-4T digital X-ray spectrometer.
