Description
On November 2, 2009, PROBA2 was launched into a sun-synchronous polar orbit. Two solar observation experiments which are test platforms for new technologies, the Sun Watcher with Active Pixels and Image Processing (SWAP) and the Large-Yield RAdiometer (LYRA) onboard PROBA2 will be introduced. I will review the design of the instruments, provide an overview of their on ground calibration but also their on-orbit degradation effects.
As a second topic, the SWORD radiometer for cubesat platform is introduced. SWORD stands for Solar Wide bandgap semicOnductor RaDiometer which is an alternative to Si technologies through the “Blind to Optical Light Detectors” (BOLD) project. The BOLD detectors under development are metal-semiconductor-metal photodetectors based on diamond and AlN materials which bring new possibilities for UV solar observations.
As a last topic, I will introduce one of the main future space missions which is the Solar Orbiter. The Extreme Ultraviolet Imager (EUI) onboard Solar Orbiter consists of a suite of two high-resolution imagers and one dual-band full Sun imager telescopes that will provide EUV (17.4 and 30.4nm) and Lyman-α (121.6 nm) images of the solar atmospheric layers. For the EUI, CMOS Active Pixel Sensors (APS) prototype have been developed. A campaign of measurements to characterize their EUV properties and degradation mechanisms will be presented.
