Beamlines | B22 - Design Specifications

Please note: these are the design specifications. Potential users should contact the B22 beamline team to discuss current capabilities.

B22 has two end stations, dedicated to confocal IR micro-spectroscopy and IR imaging. Being designed for optimum performance from the near- to the far-IR, a suite of single and array detectors equip the end stations to cover the whole IR range. The wide range of applications call for a versatile suite of sample environments and sampling methods coupled with off-line facilities for sample preparation and handling as well as results analysis.
