## Description

National Physical Laboratory require a motorised system that allows for the selection and to accurately position various filtration material in the path of the X-ray beam to provide the required radiation qualities in use\. The filter material has a significant bearing on the characteristics of the resultant X-ray beam\. The existing filter wheel system is over 20 years old and approaching end of working life\. This device is integral to the 300kV X-ray facility, as are used for all calibration work undertaken on this facility and additional research projects\.
