X06SA (PXI) was the first macromolecular crystallography beamline at the Swiss Light Source. It is equipped with a flexible two-stage focusing X-ray optics system and a single–photon counting hybrid pixel area EIGER 16M (Dectris) detector. X06SA is well suited for micro-crystals, crystallography of large unit cell structures, and single/multiwavelength anomalous diffraction experiments (SAD/MAD).
In October 2023, PXI closed for a major refurbishment as part of the SLS 2.0 upgrade. Alongside the storage ring upgrade, all three macromolecular crystallography (MX) beamlines were extensively modernised with new optics, upgraded instrumentation, redesigned experimental end stations, and enhanced software. These improvements fully exploit the increased brilliance of the new storage ring, delivering higher flux, improved beam stability, and increased automation for more efficient and reliable experiments.
