McStas: TAS1_Vana Instrument at Risoe

[ Identification | Description | Input parameters | Output parameters | Links ]

The TAS1_Vana Instrument

The conventional cold-source triple-axis spectrometer TAS1 at Risoe National Laboratory used with a vanadium sample.

Identification

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

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.
The sample is a vanadium and the analyzer is a single plate.


Input parameters

Parameters in boldface are required; the others are optional.
