The Mechanical Group support the scientific groups at the department with design, development, manufacturing, assembly and commissioning of mechanical systems. UHV vacuum systems in particular are our expertise. However, we also cover other mechanical aspects. Spectrographs for telescopes. Micro mechanism and bigger constructions. Water, pneumatic and gas systems. We use Inventor CAD system for 3D design. We have CNC milling and turning machines for manufacturing of parts. Our workshop also cover many other machining and forming techniques. Cutting, drilling, bending, rolling, welding and soldering. We have He leak detectors and a UHV ultrasonic cleaning facility. In addition, we have a laser theodolite for precise alignment.
