We are researching space charge sensing technology using photonic crystals. We have developed a fiber module incorporating a photonic crystal waveguide chip and have demonstrated space charge detection in ambient air and room temperature. This sensor module can be miniaturized and is resistant to radiation and electrostatic discharge. We aim to mount this sensor on a spacecraft and use it to detect charged particles in outer space. Very recently, we succeeded in detecting space charge under high vacuum. For use in outer space, it is desirable to be able to operate in vacuum and over a wide temperature range. This time, we will report on the initial study of thermal vacuum experiments of the module.
