Abstract
UGCT is a user facility for multidisciplinary micro-CT research. The scanners at UGCT are custom designed and built by the Radiation Physics research group (UGent). This paper describes the two latest scanners that were developed in collaboration with XRE: HECTOR, a high energy micro-CT scanner, and EMCT, a gantry based micro-CT scanner with variable magnification. HECTOR is a 240 kV 280 W system with a nominal resolution of 4 micrometer. A 40x40 cm² flat panel detector which can be tiled results in a field of view of 80x80 cm². The sample positioning stage can carry samples up to 80 kg. The second scanner, EMCT, is a gantry based micro-focus system with a variable magnification. Unlike medical or small-animal scanners, the rotation axis is mounted vertically. It was designed to allow scans of objects that are hard to rotate in a standard micro-CT scanner, such as samples that are wired to peripheral equipment or samples in a fluid environment. The source is a 130 kV 15 W microfocus source (nominal resolution 5μm) with integrated high-voltage supply. The standard detector is a 15x15 cm² flat panel detector resulting in a maximal field-of-view of 12cm diameter. In addition a high-speed detector is available which can be installed on both scanners for micro-CT of dynamic processes. To further extend the effective X-ray energy at HECTOR a high sensitivity line detector will be installed in the near future.
