In December 2018, ADC completed the design, fabrication, assembly, and testing of this 2-Axis Motion System for Elettra Sincrotone Trieste, the synchrotron facility in Italy. It was shipped on January 4th, 2019. This pair of motion stages was designed and built to hold a further set of stages which manipulate a sample for X-ray experiments. The lift stage arrangement was select to produce a more compact total height than if a more conventional jack stage was placed directly under the hexapod. Both stages are positioned using ball screws driven by stepper motors, with right-angle gearboxes to keep the overall size as small as possible. Incremental linear encoders are installed to provide position feedback for the control system.
Two of ADC’s SLT-600 UHV X-ray Slits were delivered to researchers at Lawrence Berkeley National Laboratory (LBNL) for adjustment of X-ray beam spot size and spot edge clarity in the Advanced Light Source (ALS) synchrotron. One slit system was equipped with water cooling, while the other was not. Both systems were equipped with drain current monitoring from the electrically isolated blades, allowing the position of the X-ray beam to be monitored from the intensity of radiation striking each of the four slit blades.
