Research project: RADCAPMOS

Study of a low-cost MOSFET-based sensor for measuring the dose of X-rays and gamma rays

Start date of the project: 02/10/2023

Duration of the project: 24 months

Overall budget: 149 963,63 €

Irradiations impact many sectors.

In the space field, the electronic components' features can vary according to incurred irradiations and lead to electronic systems' dysfunctions. 

In the medical field, they are used to treat some tumours or for diagnosis.

Industries producing PCBs use RX in their quality tests to detect imperfections.

These examples are not exhaustive but aim to demonstrate that radioactivity-linked applications are everywhere. Whether irradiation be voluntary or not, the common feature is the need to measure the dose coming from ionising radiations.

Various technologies exist for these measuring devices but sometimes at a very high price and a considerable degree of uncertainty regarding low dose measures. Of course, there are already systems measuring dose rates which are based on optimised MOSFET named RADFET. They are currently dedicated to the measure of more significant doses as in the radiotherapy field.

In the field of doses of small values, the measuring technique is made more complex because many settings are becoming dominant and need to be controlled to get a reliable measure.

The RADCAPMOS project involves characterising MOSFET transistors and optimising the measurement chain, in order to objectify their use to measure the dose coming from RX and gamma ionising radiations.

The aim is to analyse the possibility to use MOSFETs, that is to say low-cost sensors for measuring low doses of RX and gamma radiations.

Our team includes the project holder (Eng. Gaëtan Paulet), a teacher following the project (Eng. Cyril Fanchon) and a full-time researcher involved for a two-year period (Eng. Michaël Brogniaux). 

The acquired experience during this project may positively impact the trainings provided within the Department of Sciences and Technologies of HEH.be. This will indirectly spread throughout the companies recruiting staff coming from our training courses. With this project, the team aims for acquiring a recognition in the field of applied research in dosimetry-related electronics, more precisely in the dose measuring of ionising radiations (X and gamma), and thus taking part in bigger projects.
