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

The He3_cell Component

Polarised 3He cell

Identification

  • Author: Trefor Roberts
  • Origin: ILL
  • Date: March 1999
  • Version: 1.0

Description

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

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

WARNING: This is a contributed Component.

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
radius m radius of the cylinder  
length m length of the cylinder  
pressure bar pressure of the gas in the cell 3
p3he -1 to +1 polarisation of the 3He gas 0.7
bx tesla x component of field at the cell 0
by tesla y component of field at the cell 1e-3
