Beamline 24-ID-E: Insertion Device Beamline

NE-CAT
Life Sciences

Description

Sector 24 utilizes canted insertion devices to provide two independent x-ray sources, one for a variable energy beamline 24-ID-C (6-21KeV) and another for a fixed-energy beamline 24-ID-E (Se peak). Both beamlines are optimized to address challenging cases in macromolecular crystallography such as large complex molecular assemblies, poorly diffracting crystals and microcrystals by providing extremely stable and intense x-ray beams with beam sizes ranging from 5 to 70 microns. ALS style Robot installed on both beamlines for better productivity. Remote operations available.
