14. Measuring the efficacy of a satellite VLF transmitter with magnetic loop/solenoid antenna in a plasma chamber (proof of concept)

Prof. János Lichtenberger (Department of Geophysics and Space Sciences, Eötvös University, Budapest)

Oral presentation

This is an ongoing ESA PRODEX project, the overall objective of this project is a proof-of-concept that a VLF transmitter, with a magnetic loop/solenoid antenna on a LEO satellite, is capable of transmitting wave power in the Very-Low-Frequency and at an amplitude range comparable to the typically observed peak power of the naturally occurring whistler-mode waves (whistler, chorus, hiss) in...

30. Characterizing the Lunar Radiation Environment using Floating Gate Dosimeters

Stan Broere (Lunar Zebro)

Oral presentation

As humanity prepares for a return to the lunar surface, understanding and monitoring the lunar radiation environment is more important than ever. Despite the renewed focus on missions, the lunar radiation environment has only been measured a handful of times—mainly during flybys (Lunar reconnaissance orbiter and Chandrayaan-1) and lander missions (chang’E-4 Lander). These data are spatially...

20. Study on the effects of mixed-field irradiation on SiPM performance

Valentin Buchakchiev (Sofia University "St. Kliment Ohridski")

Oral presentation

Silicon Photomultipliers (SiPM) are a good candidate when designing the readout for modern scintillator detectors for ionizing particles, both for space-borne and Earth-based devices, due to their lower operating voltage and power consumption. A major issue, however, is that high radiation environments may degrade SiPM performance due to defects accumulating within the silicon crystal lattice....
