Description

For specific experiments at the new cold neutron triple axis spectrometer KOMPASS, a precisely aligned magnetic field is required. This field is generated using a Helmholtz coil system, which allows controlled rotation of the magnetic field in space. To prevent interference from the neutron reflecting sample striking the coil segments, the system must be rotatable out of the neutron beam. A custom-designed rotary platform was developed specifically for KOMPASS to meet this need. Due to strict requirements for low magnetic interference and a compact design, commercially available rotary stages were not suitable.

My poster introduces the development process of the rotary adapter. Which essentially consists of the rotation mechanism being driven by a stepper motor via a toothed belt and having a specially developed bearing system that is optimized for low height and minimal magnetic influence. There were some challenges encountered during assembly and initial testing, which are discussed in more detail in the poster.
