V14
Mirror Test Device
The Instrument is a simple reflectometer with a lower flux and a smaller signal-to-noise ratio compared to V 6. It is devoted to the numerous tests necessary for the develpoment and quality control of neutron optical devices, like supermirrors, benders etc. which are produced at BENSC.
A limited amount of beam time can be supplied for external users for common projects in the field of neutron optics.
