SPACEDOS: AN OPEN-SOURCE PIN DIODE DOSEMETER FOR APPLICATIONS IN SPACE.

Area of Science:

• Space Science and Engineering
• Radiation Detection and Measurement

Background:

• Accurate measurement of cosmic radiation is crucial for astronaut safety and instrument integrity on space missions.
• Existing dosimetry solutions may lack portability, adaptability, or open-source accessibility for diverse space applications.

Purpose of the Study:

• To introduce and evaluate the performance of SPACEDOS, a novel open-source dosemeter for space radiation measurements.
• To highlight the advantages of SPACEDOS, including its compact size, low power consumption, and design flexibility for various space environments.

Main Methods:

• Development of the SPACEDOS open-source dosemeter.
• Deployment and operation of SPACEDOS on board the International Space Station (ISS).
• Comparison of SPACEDOS measurements with data from traditional thermoluminescent detectors.

Main Results:

• SPACEDOS successfully performed measurements of cosmic radiation on the ISS.
• The obtained results were comparable to those from established thermoluminescent detectors.
• The dosemeter's small size, lightweight nature, and low power consumption were confirmed.

Conclusions:

• SPACEDOS is a viable and advantageous open-source solution for space radiation dosimetry.
• Its adaptability for pressurized cabins and vacuum environments makes it suitable for a range of spacecraft, including CubeSats.
• The open-source nature of SPACEDOS promotes portability and reproducibility of results in space radiation research.
