CATS: a Cryogenic Automated Transfer System installed on the beamline FIP at ESRF

CATS allows users to mount and dismount their crystal samples remotely on the diffractometer, without entering the experimental hutch. CATS has been integrated into the automated control of FIP, allowing users to choose the wavelengths, optimize the beam intensity, mount and screen their crystal sample automatically and finally record diffraction data on the best sample(s).
