PROXIMA 1 is one of two beamlines at SOLEIL for measurements in macromolecular crystallography (together with PROXIMA 2, recently opened to users). PROXIMA 1, operational since March 2008, delivers an intense, parallel and tunable x-ray beam for measurements at high resolution or from large unit cell dimension crystals. The beamline has recently been upgraded with a very large surface area detector (PILATUS 6M). The 3 circle "kappa" geometry goniostat is in routine use for advanced data collection strategies. A new CATS sample changing robot has been installed on the beamline and is operational for cryogenically cooled samples. A crystallisation plate screening option will be available soon. The beamline optics implemented are such that they could permit a range of focussing conditions which can then be adapted to the sample being studied (for example beam focus at sample or detector).
