Multilayer Polarimeter
A versatile multilayer-based polarimeter with five high precision rotation axes allows the analysis of polarization of the photon beam at the beamline. It is based on rotating both the transmission (acts as polarizer) and the reflection multilayers (acts as analyzer) around the photon beam.
The polarimeter is designed to cover a wide energy range from EUV to soft x-ray for the MAX IV laboratory. Its hexapod support with jacking castors gives a high accuracy, automated alignment and allows it to be easily transferred between different beamlines.
- Five high precision rotation axes
- High vacuum compatible (10-7 Pa)
- Covers wide energy range: 100 – 1200 eV by a set of multilayers (Mo/Si, Cr/C, Sc/Cr and W/B4C)
- Up to 5 transmission and 5 reflection multilayers can be mounted and are interchangeable in high vacuum condition
- High stability
- High accuracy and easy alignment by means of hexapod support
- Ultra-high accuracy in manufacturing and assembling made by TOYAMA
