A Review of Semiconductor Based Ionising Radiation Sensors Used in Harsh Radiation Environments and Their Applications

Abstract

This article provides a review of semiconductor based ionising radiation sensors to measure accumulated dose and detect individual strikes of ionising particles. The measurement of ionising radiation (γ-ray, X-ray, high energy UV-ray and heavy ions, etc.) is essential in several critical reliability applications such as medical, aviation, space missions and high energy physics experiments considering safety and quality assurance. In the last few decades, numerous techniques based on semiconductor devices such as diodes, metal-oxide-semiconductor field-effect transistors (MOSFETs) and solid-state photomultipliers (SSPMs), etc., have been reported to estimate the absorbed dose of radiation with sensitivity varying by several orders of magnitude from μGy to MGy. In addition, the mitigation of soft errors in integrated circuits essentially requires detection of charged particle induced transients and digital bit-flips in storage elements. Depending on the particle energies, flux and the application requirements, several sensing solutions such as diodes, static random access memory (SRAM) and NAND flash, etc., are reported in the literature. This article goes through the evolution of radiation dosimeters and particle detectors implemented using semiconductor technologies and summarises the features with emphasis on their underlying principles and applications. In addition, this article performs a comparison of the different methodologies while mentioning their advantages and limitations.

Optical Fiber-Based Monitoring of X-ray Pulse Series from a Linear Accelerator

“…This is proposing to activate radiative and non-radiative recombinations from atomic structure, which are initially passive. They reach the excitation states by the energy deposited in the atomic structure, which generates charge [56]. The recombination is then initiated by the energy stimulation.…”

A Review of PRESAGE Radiochromic Polymer and the Compositions for Application in Radiotherapy Dosimetry

“…The TLD is stimulated by heat, while the optically stimulated luminescent dosimeter (OSLD) is stimulated by light [ 28 ]. In a semiconductor detector, irradiation causes the semiconductor to produce electron-hole pairs that are proportional to the radiation dose [ 29 , 30 ]. As a result, the dose absorbed by the semiconductor dosimeter can be read instantly [ 31 ].…”

Monolayer Graphene Radiation Sensor with Backend RF Ring Oscillator Transducer

“…Solid-state detectors have gained much attention recently due to their simplicity, low cost, and high sensitivity [ 14 ]. In addition, semiconductor-based solid-state radiation sensors are widely used because they can generate numerous electron–hole pairs in response to incident radiation generated at low photon or particle energies, compared to conventional scintillators [ 15 ]. Solid-state radiation sensors and the materials used in them can be classified into two main classes: single detectors, which are mainly fabricated using silicon, germanium, or metals (e.g., platinum) and compound detectors, containing at least two elements (e.g., thallium bromide or thallium gallium selenide), which were proposed because Si and Ge single detectors need low temperatures to work efficiently at low noise levels [ 16 , 17 , 18 ].…”
