DC14: Development of satellite-borne instruments to investigate negative ions at airless planetary bodies

Swedish Institute of Space Physics (IRF)

My academic path started when I was an undergraduate student in Physics at Kasetsart University in Bangkok, Thailand. During my studies, I had the opportunity to join researchers from Mahidol University on a field trip to conduct an experiment at a neutron monitor station to measure cosmic rays at Doi Inthanon, the highest mountain in Thailand, along with simulation-based learning. That experience was my first inspiration to become interested in particle detectors. After that, I was selected to participate in the DESY Summer Student Program 2022 in Hamburg, Germany, for about two months. I joined the Particle Physics Group in ATLAS, and my research project focused on silicon pixel detector development using Allpix2 simulations. During that time, I became highly motivated to learn more about detector principles. I completed my bachelor’s degree in 2023 with a physics project on the calibration of a silicon PIN detector using terrestrial cosmic ray detection through both experiments and simulations.

When I continued my master’s degree at Mahidol University in Bangkok, Thailand, I worked on particle instrumentation and gradually moved toward space missions. My master’s thesis focused on testing a charged particle detector prototype using a high-altitude survey balloon and was completed at the end of 2025. During that time, I had the opportunity to intern at KTH Royal Institute of Technology in Stockholm, Sweden, where I worked on the recalibration of an actual satellite payload, a compact X-ray detector called CUBES in the MIST project. I started my PhD life in Space Physics at IRF, Kiruna, in 2026, where my research focuses on the NILS space instrument and the study of negative ions on the lunar surface. Therefore, studying negative ions in space is an exciting next chapter in my academic journey.
