McStas: ISIS_Prisma2 Instrument at ISIS

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

The ISIS_Prisma2 Instrument

Simple simulation of PRISMA2 with RITA-style analyser backend.


  • Site: ISIS
  • Author: Kristian Nielsen and Mark Hagen
  • Origin: ISIS/Risoe
  • Date: August 1998.
  • Version:(Unknown)


Demonstrates how the standard components from the component library
may be easily modified for special purposes; in this case to have
the individual analyser blades paint a "color" on the neutrons to
differentiate them in the detector.

Output is in the file "prisma2.tof". The format is ASCII; each
line consists of the time-of-flight in microseconds followed by seven
intensities of neutrons from each individual analyser blade.

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
TT deg Take-off angle at the sample position, aka A4 -30
PHA deg Analyzer group rotation angle, aka A5 22
PHA1 deg Analyzer 1 tilt angle -3
PHA2 deg Analyzer 2 tilt angle -2
PHA3 deg Analyzer 3 tilt angle -1
PHA4 deg Analyzer 4 tilt angle 0
PHA5 deg Analyzer 5 tilt angle 1
PHA6 deg Analyzer 6 tilt angle 2
PHA7 deg Analyzer 7 tilt angle 3
TTA deg Take-off angle at the analyzer position, aka A6 4
