Velocity Selector Tilt

Motor that controls tilting of velocity selector and subsequently wavelength and wavelength spread.

System Name: VSTilt

Type: Motor

Brief Description

The selector monochromates the beam and is the official start of the SANS instrument. It has two parameter, speed and tilt angle, which control the wavelength and wavelength spread. The relationship between the wavelength parameters and motor parameters is different for each selector and obtained by calibration. Note that VSTilt device controls only velocity selector tilting.
