PROXIMA-1 (PX1) is one of two beamlines at SOLEIL for measurements in macromolecular crystallography (together with PROXIMA-2A). PX1, operational since March 2008, delivers an intense, nearly parallel and tunable x-ray beam for measurements at high resolution or from large unit cell dimension crystals.
Equiped with a very large surface area detector (EigerX 16M) and coupled to the latest generation three-circle Chi geometry goniostat, advanced data collection strategies are routine at the beamline for complex experimental phasing. High-throughput data collection takes advantage of a robust sample changer robot of the CATS family. Mostly targeted towards cryogenically cooled samples, the robot can also handle in situ microfluidic devices.
This beamline is not part of CALIPSOplus financing program. It had access to the iNEXT financing program (http://www.inext-eu.org/), currently under revisiting.
