Gamma ray detectors measure electromagnetic radiation through the process of the counting and measuring the energy of individual photons emitted from elements.
The most common applications of silicon detectors are in charged-particle spectroscopy and the Compton-recoil spectroscopy of high-energy gamma rays.
Gamma-ray spectroscopy has used solid-state detection media besides germanium and silicon.observing the effects they have on matter, gamma rays can be found.
A gamma ray can push an electron to a higher energy level or collide with it and cause it to scatter like a pool cue (Compton scatter) (photoelectric ionization). Additionally, due to the high energy of gamma rays, some of this energy can be directly converted into matter by producing an electron and another particle (called a pair production).
The fact that electrons move as a result of each of these interactions indicates that an electric current has been produced. These currents can then be amplified and measured to determine the original gamma-energy ray’s and direction. By observing the effects they have on matter, gamma rays can be found.
Global gamma ray detector market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
SIRI-2 to Qualify Technologies for Radiation Detection in Space.scientists launched the second Strontium Iodide Radiation Instrument (SIRI-2) instrument onboard Space Test Program (STP) Sat-6. SIRI-2, a gamma-ray spectrometer, will demonstrate the performance of europium-doped strontium iodide gamma ray detection technology with sufficient active area for Department of Defense (DoD) operational needs.
The first SIRI mission was launched onboard STP Sat-5 with a one-year mission to investigate the detector’s response to on-orbit background radiation in low Earth orbit (LEO). The much larger, SIRI-2 instrument is operating in a geosynchronous orbit where the radiation background is significantly different in composition.
The technology being demonstrated in SIRI-2 will need to detect small radiation signatures or signals in the highly variable background radiation fields found in space. The instrument will also study transient phenomena, such as solar flares during the one-year mission.”
The SIRI line of instruments is designed to space-qualify new gamma-ray scintillator materials and readout electronics.A scintillator is a material that exhibits the property of luminescence when excited by ionising radiation and is commonly used for radiation detection.
Luminescent materials, when struck by incoming particles, absorb its energy and re-emit the absorbed energy in the form of visible light.
