Some instruments are equipped with a Dornier Chopper system running one or more choppers:
a disk chopper and possibly a fermi chopper. In most situations the diskchopper is
in slave mode. This means his speed is a predefined ratio of the
speed of the fermichopper. Furthermore, there is a phase difference between
the two choppers in order to allow for the fligh time of neutrons
