ATHENA mission is approved by European Space Agency as a large mission L2 with a launch foreseen in 2028. X-IFU (X-ray Integral Field Unit) instrument on-board ATHENA satellite will propose the unique detector system able to analize the energy spectra with resolution of 2.5eV at 1kEV. WFI (Wide Field Instrument) instrument on-board ATHENA satellite will be able to detect (in wide field of view) the signals with very precise time resolution. CBK PAN is responsible for PDU systems for both instruments and Filter Wheel in WFI.
