Irradiation and calibration of RADFET sensors for Varadis

Varadis entrusted ATRON Metrology with the irradiation of its RADFET sensors for calibration purposes, as part of their space and scientific applications.

Space Dosimetry Semiconductor

Description

A global provider of radiation measurement technologies, Varadis develops RADFETs (Radiation-Sensitive Field-Effect Transistors) used in the fields of space, healthcare, and research.

To ensure the accuracy of its sensors, Varadis requested ATRON Metrology to carry out a controlled open-air irradiation at ambient temperature for dose rate calibration.

Using our FELIX electron accelerator, we delivered a total dose of 10 kGy at a constant dose rate of 500 Gy/h over 20 hours, with beam stability exceeding 99.8%.

This operation enables Varadis to guarantee the traceability and performance of its sensors in demanding environments, particularly for on-board space applications.
