Gamma rays from a nuclear explosion produce high-energy electrons throughCompton scattering. These electrons are captured in the earth’smagnetic field, at altitudes between 20 and 40km, where they resonate. The oscillatingelectric currentproduces a coherentelectromagnetic pulse(EMP) that lasts for appr...
It is by now clear that gamma-ray bursts originate from a spherically symmetric collapse of a massive star into a black hole endowed with electromagnetic structure (EMBH). Such theoretical approach has been confirmed to a very high level of accuracy in the explanation of the time variability, ...
High-energy astrophysics is the study of the processes that occur within stars, black holes and supernovae. These processes can be monitored by measuring the high-energy electromagnetic radiation and particles that they emit including x-rays, ultraviolet light and gamma rays. These observations are...
“Electron beams damage cancer cells in a very similar way to that of high-energy photons, which is the most common radiotherapy modality in the clinic,” Jaroszynski explains. “This is because high-energy electrons convert a large fraction of their kinetic energy to X-ray photons by bremsst...
Two sections of heat-treated (HT) and non-heat-treated (NHT) Cable-in-Conduit Conductor (CICC) of a design similar to the ITER tokomak have been imaged using very high energy X-ray tomography at the ESRF beamline ID19. The sample images were collected at four temperatures down to 77 K...
Before the launch, we calibrated the detectors by measuring the energy spectra of all strips using γ-ray sources. To evaluate the overall performance of the HEP instruments, we measured the energy spectra and angular responses with electron beams. After HEP was first put into operation, on ...
(of the amplitudes or energy densities) of some of such GWs are just distributed in the GHz or higher frequency band, which would be an optimal frequency band for the electromagnetic (EM) response to such high-frequency GWs (HFGWs). In this paper we investigate the EM response to the HF...

摘要: Evidence of TeV -ray astronomy, as the highest energy band, provides important information that is hard to obtain from longer wavelength electromagnetic radiation. The current status of TeV -ray observations also considered. 被引量: 2 年份: 2002 收藏 引用 批量引用 报错 分享 全部...
Here we describe how a satellite in lunar orbit equipped with an electromagnetic vector sensor could detect Askaryan pulses induced by neutrinos interacting with the moon. The threshold neutrino energy is found to be 50 EeV for this setup, and the sensitivity is determined from simulations. A ...
