High-resolution low-energy diffractometer
Review of Scientific Instruments, 1976A high-resolution low-energy electron diffractometer is described. Motivation for its design features is provided and data obtained in several operating modes using an Al(100) target surface are displayed. These modes of operation include LEED, ILEED, AES, and ELS (electron loss spectroscopy).

High energy resolution plastic scintillator
SPIE Proceedings, 2016In this paper we present results on a novel tin-loaded plastic scintillator. We will show that this particular plastic scintillator has a light output similar to that of BGO, a fast scintillation decay (< 10 ns), exhibits good neutron/gamma PSD with a Figure-of-Merit of 1.3 at 2.5 MeVee cut-off energy, and excellent energy resolution of about 12% (FWHM)

NaI(Tl) electron energy resolution
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2002Abstract NaI(Tl) electron energy resolution ηe was measured using the Modified Compton Coincidence Technique (MCCT). The MCCT allowed detection of nearly monoenergetic internal electrons resulting from the scattering of incident 662 keV gamma rays within a primary NaI(Tl) detector. Scattered gamma rays were detected using a secondary HPGe detector in

Spectroscopy with meV energy resolution
Journal of Physics: Condensed Matter, 2001Inelastic x-ray scattering has become a powerful tool in condensed matter physics in recent years. This is due to the advent of the third-generation synchrotron radiation sources, which provide an intense and collimated x-ray beam, and due to improvements in x-ray optics.

Energy resolution of scintillation detectors
SPIE Proceedings, 2005The limitations of energy resolution of scintillation detectors are discussed with a special emphasis on non-proportionality response of scintillators to gamma rays and electrons, which is of crucial importance to an intrinsic energy resolution of the crystals. Examples of the study carried out with different crystals and particularly those of tests of

Energy Resolution of LGSO Scintillators
IEEE Transactions on Nuclear Science, 2006Several LGSO samples with different Ce doping were studied in comparison to a GSO crystal. The light output, non-proportionality of the light response, energy resolution and intrinsic resolution were measured and compared to the intensity of the afterglow recorded in the second range of time.

A high energy resolution, high spatial resolution photoemission microscope
Surface and Interface Analysis, 1990Abstract This paper will discuss a microscope that allows high energy resolution spectroscopy to be performed at high spatial resolution. This instrument uses a high magnetic field to contain and focus electrons emitted from the sample surface and has a two‐dimensional detector that records a photoelectron image.

An Energy Modulated High Energy Resolution Electron Spectrometer
Review of Scientific Instruments, 1971A new cylindrical retarding potential difference type or energy modulated electron spectrometer has been constructed with high energy resolution. For energies greater than 1 eV the ratio of beam current I to energy spread FWHM, ΔE has been found to be approximately constant so that I/ΔE≃10−7 (A/eV) at about 20 eV.

Benchmarking NaI(Tl) electron energy resolution measurements
IEEE Transactions on Nuclear Science, 2002A technique for validating electron energy resolution /spl eta//sub e/ results measured using the modified Compton coincidence technique (MCCT) has been developed. This technique relies on comparing measured gamma-ray energy resolution /spl eta//sub /spl gamma// with calculated values that were determined using the measured /spl eta//sub e/ results ...

The Energy Resolution of Calorimeters
2019In particle physics experiments, the energy resolution is often considered the most important performance characteristic of a calorimeter. In this chapter, the various factors that contribute to and limit the energy resolution of practical calorimeters are discussed.
