McStas: He3_cell

[ Identification | Description | Input parameters | Links ]

The He3_cell Component

Polarised 3He cell

Identification

  • Site:
  • Author: Trefor Roberts & Erik B Knudsen
  • Origin: ILL/DTU Physics
  • Date: March 1999

Description

Simple cylindrical polarised 3He neutron spin filter cell.
The glass container for the cell is not included in the model.

This component has been validated against:
Batz, M, Baessler, S, Heil, W, et al., J Res Natl Inst Stand Technol. 2005;110(3):293–298.

Example: He3_cell(radius=0.1,length=.2,pressure=3,p3he=0.7,bx=0,by=1e-3,bz=0)

Input parameters

Parameters in boldface are required; the others are optional.
