Varadis radiation sensors chosen by Center for Astronautical Physics and Engineering, National Central University in Taiwan for its Deep Space Radiation Probe

CORK, IRELAND, June 27, 2023/EINPresswire.com/ -- Varadis, the leading provider of high-energy radiation detection sensors, is pleased to announce that its radiation detection sensors have been chosen by the Center for Astronautical Physics and Engineering, National Central University in Taiwan to measure ionized radiation via its Deep Space Radiation Probe (DSRP). The DSRP probe is planned to be launched to the moon aboard a lunar lander in 2024.

For the probe on this mission, the center has chosen the Varadis RADFET (Radiation Sensing Field Effect Transistors) VT01, mounted on an RM-VT01-A read-out module, which can detect a radiation dosage up to of 100 krad/1kGy. The RADFET, a discrete p-channel MOSFET optimized for radiation sensitivity, is sensitive to detect ionizing radiation including gamma rays, X-rays and protons.

“The ionizing radiation environment of outer space is a challenge that must be dealt with in spaceflight, due to both its degrading effects on spacecraft electronics, as well as its health effects on biological organisms,” says Loren Chang, Ph.D., Distinguished Professor at Center for Astronautical Physics and Engineering, National Central University. “As ionizing radiation levels are particularly serious in the deep space regions beyond Low Earth Orbit, it's crucial we measure radiation dose and dose rate, while also counting radiation induced bit errors in its flash memory.”

Due to the Varadis RADFET’s ability to accurately measure significant doses of absorbed ionizing radiation (up to 10 kGy/1 Mrad) without requiring power, Varadis radiation detection sensors have been designed into space exploration missions by international space agencies, including:

- NASA (National Aeronautics and Space Administration)
Varadis RADFETs measure radiation doses on the International Space Station and in the Orion crew module of Artemis lunar missions
 
- ESA (European Space Agency)
Varadis designs and manufactures plug-and-play radiation detection modules for ESA satellites

- JAXA (Japan Aerospace Exploration Agency)
Varadis RADFET was the radiation sensor of choice for JAXA programs Mission Detection test Satellite 1 (MDS-1) and Small Demonstration Satellite (SDS-1)

In addition to their use in space communications and exploration, Varadis radiation detection sensors are used in physics research, medical, security and public safety applications.

“We’re delighted and honored to have the opportunity to support the Center for Astronautical Physics and Engineering on this important lunar mission,” says Brad Wrigley, CEO of Varadis. “Varadis radiation detection sensors and modules are seen as a leading technology globally for radiation measurement; from space exploration through to cancer radiotherapy treatment. The ability to successfully serve such a diverse range of markets is true testament to the incredible work of our Varadis R&D team.”
