An Innovative Real-Time Dosimeter for Radiation Hardness Assurance Tests

Abstract

The study of the effects of the radiation dose on devices and materials is a topic of high interest in several fields, including radiobiology, space missions, microelectronics, and high energy physics. In this paper, a new method, based on radiochromic film dosimetry, is proposed for real-time dose assessment in radiation hardness assurance tests. This method allows for correlating the radiation dose at which devices are exposed to the radiation effects (malfunctioning and/or breakdown). In previous studies, it has already been demonstrated that a system, based on optical fibers and a spectrometer, allows for the real-time dose assessment of radiochromic films. The current study not only validates our previous results, but shows that it is possible to apply the new method to an actual radiation environment for the real-time measurement of the dose delivered to a device in radiation hardness assurance tests. This new dosimeter can be used in different radiation environments for a wide dose range, from a few Gy to a few MGy. This high sensitivity can be reached by changing the radiochromic film type and/or the parameters used for the analysis.

New opto-electro-mechanical sensor for two-dimensions dosimetry based on radiochromic films

“…For instance, Casolaro et al proposed a set-up based on optical fibres 25 , where the films are located on the tip of fibres and the light is backscattered after passing into the films and the sent to a spectrometer. The last study of this group has demonstrated the radiation hard feature of the system (from a few Gy to a few MGy) 26 . Nevertheless, the features of this system make difficult its use for daily dose monitoring due to the bulky instruments used (spectrometer and power light source) and particularly since it is able to measure only one spot.…”

Effect of fresnel lens distance on the output power of the prowe plant solar-based electricity transistor 2N3055

“…Currently, the use of Fresnel lenses is often the preferred choice for concentrating solar energy. Plastic Fresnel lenses offer several advantages, being stable polymers with optical properties similar to glass, clear, lightweight, highly producible, cost-effective, and efficient in increasing energy density [7]. Specifically, the Fresnel lens made from plastic, commonly known as PMMA (polymethylmethacrylate), exhibits a refractive index of 1.49, comparable to glass.…”

“…One alternative that can be considered is building a power plant using the 2N3055 transistor, which is readily available and more affordable than solar panels. Several studies have been conducted on the creation of power plants using transistors [1] [4] [7]. However, the results obtained from the constructed power plant can still be optimized with supporting components.…”
