Microfabricated high-energy particle detector
Sensors and Actuators A: Physical, 1996An array of high energy particle detectors, or pixels, have been realized in a silicon substrate using Microfabrication technology. The pixels are operated in a gaseous chamber where the original electrons, ionized by a incident high energy particle, are amplified through a gas avalanche process, and induce a voltage signal at the pixel anode.

As mentioned before, the energy detector senses spectrum holes by determining whether the primary signal is absent or present in a given frequency slot. The energy detector typically operates without prior knowledge of the primary signal parameters.

In lens BSE detector with energy filtering
Ultramicroscopy, 2018We present a new type of an in-lens detector designed for Thermo Fisher Scientific (FEI) electron microscopes with the Elstar column. A key feature of it is high-pass energy filtering to enable the detection of low-loss backscattered electrons with their energy close to the primary beam energy.

A phoswich detector for high-energy neutrons
Radiation Protection Dosimetry, 2007A phoswich detector was developed to measure neutron energy spectra from a few MeV to a few hundreds MeV in aircrafts and space crafts. Radiation fields, which both crafts are exposured, consist of neutrons, gamma rays, protons, etc. The phoswich detector can measure neutrons separately from gamma rays and protons.

An energy efficient epileptic seizure detector
2018 IEEE International Conference on Consumer Electronics (ICCE), 2018Epilepsy is one of the most common neurological disorders affecting up to 1% of the world's population and approximately 2.5 million people in the United States. Seizures in more than 30% of epilepsy patients are resistant to anti-epileptic drugs.

Energy detectors for sparse signals
2010 IEEE 11th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2010In this paper, compressive sampling (CS) based energy detectors are developed for sparse communication signals, namely, pulse-position modulation (PPM) and frequency shift-keying (FSK) signals so as to reduce the complexity and sampling rate at the receiver. We focus on noncoherent detection, thereby avoiding the channel estimation step.

Energy detector for the linac at ANU
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1996Abstract The linac booster at ANU consists of superconducting Split Loop Resonators (SLRs). Each SLR needs to be individually tuned in phase and its amplitude set, for optimum acceleration efficiency. The superbuncher amplitude and phase also has to be correctly set to obtain the time focal length for the bunched beam.

Energy resolution of scintillation detectors
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2016Abstract According to current knowledge, the non-proportionality of the light yield of scintillators appears to be a fundamental limitation of energy resolution. A good energy resolution is of great importance for most applications of scintillation detectors. Thus, its limitations are discussed below; which arise from the non-proportional response of

A detector for intermediate energy neutrons
Nuclear Instruments and Methods, 1963Abstract An intermediate energy neutron detector has been developed, consisting of a small wax sphere surrounding a boron-loaded scintillation counter. The energy dependence of the detector was tested using the Harwell “neutron booster”, which provides short pulses of neutrons whose energies may be measured by time-of-flight techniques.
