23-ID-D: Sector 23 - Insertion Device D
Life Sciences
Sector 23 uses canted undulators to provide two independent sources for 23-ID-B (U33) and 23-ID-D (U30). The beamlines support macromolecular crystallography, with capabilities for micro-crystallography, serial crystallography, large-unit-cell crystallography, and MAD/SAD phasing. On- and off-axis microscopes provide parallax-free sample alignment. The new mirrors can focus the beam to smaller than 5 microns, with ~6x10^13 photons/s at 12 keV. Using both the mirrors and Compound Refractive Lenses (CRLs) in a transfocator the beam size can be varied from 1-50 microns in a few seconds, with ~4x10^13 photons/sec at 12 keV. The sample goniometer has a ~200 nm (peak-to-peak) sphere-of-confusion, ideal for micro-crystals. A powerful, user-friendly software interface (PyBluIce-EPICS) provides the ability to raster-scan the diffractive or fluorescence properties of a sample to locate micro-crystals, record serial crystallography data, or map the properties of larger crystals. The effects of radiation damage can be mitigated by spreading the dose over a 3-dimensional vector. A high-capacity (288 pin bases) ALS-style sample automounter provides high-throughput sample screening. The automounter accommodates ALS-style pins in Unipuck pucks.
