Space technology: Radiation detectors and embedded systems
Solar and Heliospheric Observatory/ERNE
Solar and Heliospheric Observatory (SOHO) is a joint research program run by the ESA and NASA. The SOHO space probe is studying the deep core of the sun, the corona and solar winds. ASRO's founders played a key role in developing SOHO's Energetic and Relativistic Nuclei and Electron (ERNE) particle detector. The development work covered the design and testing of ERNE's sensors, electronics, on-board data analysis software and ground support equipment as well as calibration of the instrument after its completion. SOHO and ERNE are still in operation, and this successful research program has already continued for over 20 years.
Solar Intensity X-ray and Particle Spectrometer (SIXS) is a joint project of ESA and JAXA, and one of the scientific payloads to fly on the BepiColombo Planetary Orbiter that is studying Mercury. SIXS consists of two sub-systems: an X-ray detector (SIXS-X) and a particle detector (SIX-P) that operate independently but are packaged into the same sensor unit housing. ASRO designed the readout electronics for the particle detector and played an important role in designing, testing and calibrating the particle detector.
The Low Energy Telescope (LET) particle detector was designed for ESA's Solar Orbiter (SolO). The detector was designed to identify solar wind elements from hydrogen to nickel with excellent element and energy resolution. ASRO designed the readout electronics for the detector, including the FPGA development work for the demonstration model.
The Energetic Particle Telescope (EPT) is a compact and modular ionizing particle radiation spectrometer. It is designed for the near-Earth space environment, particularly for various parts of the radiation belts. ASRO did the design and processing for the silicon detectors in the A/B/C stages in cooperation with the Microelectronics Laboratory at the University of Turku.
The European Crew Personal Active Dosimeter (EuCPAD) project is a radiation monitoring, dosimetry and data storage system for the astronauts on the International Space Station (ISS). ASRO participated in the system design of the electronics (which were based on the PC-104 standard), including a graphic interface that utilizes a touch screen.
The Charged Particle Telescope (CPT) was designed to measure ionizing solar wind radiation in near-Earth space from a satellite. ASRO carried out a phase A study for an instrument that can provide high-precision data for scientific purposes and technology applications.
The Alpha Magnetic Spectrometer (AMS-02) is a state-of-the-art particle particle physics detector that operates as an external module on the International Space Station (ISS). ASRO supplied software for the AMS ground support equipment.
ASRO was involved in developing the University of Turku's RADMON radiation detection instrument, which was carried on Aalto University's Aalto-1 nanosatellite.
