摘要：

A small-angle detector will complete the performance of the cold time-of-flight spectrometer FOCUS at the Swiss Spallation Source SINQ of the Paul Scherrer Institute, Villigen, Switzerland. It is constructed from position-sensitive He-3 tubes located 2.5 m away from the sample, and covers an area of about 95 x 70 cm(2) with a spatial resolution of approximately 1.5 cm. The 2D detector is located within a vacuum chamber, next to the argon chamber of the existing large angle detectors, and covers an angular range from 2 to 22 degrees. Commissioning of the 2D small angle detector will start in spring 2006.
