RSICC CODE PACKAGE CCC-751

1. NAME AND TITLE

ELEORBIT: 3-D Simulation of Electron Orbits in Magnetic Multipole Plasma Source.

 

2. CONTRIBUTORS

Department of Thermonuclear Fusion Research, Japan Atomic Energy Research Institute, Naka-machi, Naka-gun, Ibaraki-ken Japan, through the Nuclear Energy Agency Data Bank, Issy-les-Moulineaux, France.

 

3. CODING LANGUAGE AND COMPUTER

Fortran-77; IBM PC (C00751PCX600).

 

4. NATURE OF PROBLEM SOLVED

Performance characteristics of a magnetic multipole plasma source depend strongly on the structure of the line-cusp magnetic fields and the behavior of the primary electrons. In order to design and improve the plasma source efficiently, a computer code was developed which can simulate primary electron orbits in the three-dimensional magnetic field generated in the source.

 

5. METHOD OF SOLUTION

ELEORBIT solves the equation of motion for primary electrons in a multipole magnetic field from a JT-60 ion source. The magnetic field is determined using 3D analytical solution based on a magnetic charge model.

 

6. RESTRICTIONS OR LIMITATIONS

A Microsoft Windows OS is required. The installation was tested on Microsoft XP sp3 and Microsoft 7.

 

7. TYPICAL RUNNING TIME

The sample input requires about 60 seconds.

 

8. COMPUTER HARDWARE REQUIREMENTS

A PC with Microsoft Windows installed.

 

9. COMPUTER SOFTWARE REQUIREMENTS

The input instructions are given in EXCEL format so Microsoft EXCEL is required.
