The operation of scintillation and solid state detectors for gamma-ray astronomy is the same as it is for X-ray astronomy. We've described the basics of these types of detectors on theX-ray Detectorpage. Below we describe three types of detectors used uniquely for gamma-ray astronomy: Compto...
1 and 2.3.2 TYPES OF DETECTORSMany different detectors have been used to register the gamma ray and its eneqgy.In NDA, it is usually necessary to measure not only the amount of radiation emanatingfrom a sample but also its energy spectrum. Thus, the detectors of most use in NDA...
Depending on the energy of the initial cosmic gamma ray, there may be thousands of electrons/positrons in the resulting cascade that are capable of emitting Cerenkovradiation. As a result, a large "pool" of Cerenkov light accompanies the particles in the air shower. Air Cerenkov detectors, as...

Gamma-Ray Detectors 来自 Semantic Scholar 喜欢 0 阅读量: 47 作者:WL Dunn,DS Mcgregor 摘要: The common methods of analyzing gamma-ray spectra obtained from detectors capable of energy discrimination are discussed. Gamma-ray spectra generally are in the form of detector response versus discrete ...
摘要: PURPOSE: To obtain γ-ray detector for measuring absorbed dose of γ-ray in which spatial dose rate at same position can be measured through a single detector while switching between two types of energy characteristics corresponding, respectively, to Gy and Sv....
X-123 represents the culmination of 14 years of X-ray detector development at Amptek. Our philosophy has always been to create small, low power, high performance instruments while keeping them simple to operate. The X-123CdTe exemplifies this philosophy in a single package. Al...
Historically, gamma-ray detectors sensitive to this energy range have been collimated, well-type instruments in which the primary detector (often an inorganic scintillator such as NaI or CsI) is surrounded by an active or passive shielding structure. The field of view of the telescope is ...
Performance of the most recent avalanche photodiodes for future X-ray and gamma-ray astronomy We report on the performance of the most recent avalanche photodiodes produced by Hamamatsu Photonics, as low-energy X-rays and γ-rays detectors. APDs sha... J Kataoka,T Ikagawa,Y Yatsu,... - Pr...
CdTe and CdZnTe X-ray and gamma ray detectors in the form of single elements or as monolithic segmented arrays have been shown to be useful in imaging systems utilized in medical, research or industrial applications. These detectors possess inherently better energy resolution than scintillators couple...
