| Abstract |
As we go to brighter light sources and time resolved ex-periments, different approaches for executing faster scans in synchrotrons are an everpresent need. In many light sources, performing scans through a sequence of hardware triggers is the most commonly used method for synchronizing instruments and motors. Thus, in order to provide a sufficiently flexible and robust solution, the XRay Imaging Beamline (IMX) at the Brazilian Synchrotron Light Source [1] upgraded its scanning system to a NI PXI chassis interfacing with Galil motion controllers and EPICS environment. It currently executes pointtopoint and onthefly scans controlled by hard-ware signals, fully integrated with the beamline control system under EPICS channel access protocol. Some approaches can use CSStudio screens and automated Python scripts to create a userfriendly interface. All pro-gramming languages used in the project are easy to use and to learn, which allows high maintainability for the system delivered. The use of LNLS Hyppie platform [2, 3] also enables software modularity for better compatibil-ity and scalability over different experimental setups and even different beamlines.
