McStas: TAS1_C1_Tilt

[ Identification | Description | Input parameters | Links ]

The TAS1_C1_Tilt Instrument

The conventional cold-source triple-axis spectrometer TAS1 at Risoe National Laboratory used as a diffractometer for a collimator tilt alignment.

Identification

  • Site: Risoe
  • Author: A. Abrahamsen, N. B. Christensen, and E. Lauridsen
  • Origin: Risoe
  • Date: 1998

Description

This instrument is the conventional cold-source triple-axis spectrometer TAS1
at Risoe National Laboratory. It does not exist anymore, but was used as the
first detailed work performed with the McStas package.
Here it is used as a diffractometer for a collimator tilt alignment. The
detector is at the sample position and there is no analyzer.

Input parameters

Parameters in boldface are required; the others are optional.
