Extension of the IXS High Resolution Monochromator for the RIXS experiment at the Petra III Beamline P01 | |
|
||
| The IXS High Resolution Monochromator at P01 is used for the intermediate X-Ray regime from 2.5keV to 3.5keV. The core component is a disk that carries the crystals. At the circumfence an encoder ring is mounted. A radial and axial runout of less than 1µm during the rotation is guaranteed by a high precision spindle bearing. The rotation is done by a PiezoLEG with a 110mm long ceramic bar that is coupled to the disk via a wire and provides an angular resolution better than 100nrad. The setup is in operation since mid 2017 with four crystals. In spring 2021 two additonal moving units where installed to position eight crystals in total. An enlargement of the angular range for the in-line setup is planned for spring 2024. | ||
