XRISM’s filterwheel
06 APR. 2023 publication date 985 Views

This filterwheel of the XRISM satellite was developed by SRON in the Netherlands. Each filter can be placed over the Resolve instrument and serves a different goal. There is a molybdenum grey filter to reduce the overall brightness of a source. The one made of beryllium filters out X-rays of unwanted energy. Another filter is made of polyimide-aluminium and avoids ambient contamination. The filter wheel also has space for filters to calibrate the Resolve instrument. This includes a radioactive 55Fe filter and modulated X-ray sources (MXS) to calibrate the energy scales of the instrument.
