Negative Ion Extraction
|
nIGUN is the first program for negative hydrogen ion sources, which
is based on a self-consistent theory of the plasma sheath in negative hydrogen
and deuterium plasma ion sources (--> Download "H-_Extraction.pdf). It can take into account the space charge
effects of electrons, negative hydrogen ions and up to 10 kinds of positive ions,
like fast protons, thermal cesium ions and different kinds of molecular ions,
which are essential ingredients of H- ion sources.

New Window versions
available
|
All programs now will run under the latest WINDOWS versions. EGN2, the
PC version of the famous EGUN program always has been running under all OS. By
patches, which were supplied by Microsoft in response to the worm "sasser", older
programs could no longer operate. Now we have made console versions for POLYGON,
ANALYSE, and INTMAG. IGUN and nIGUN became real WINDOWS applications with interactive coloured graphics.

Electron Beams
and Electron Optics
|
EGN2 is the most reliable and most established electron gun and
trajectory optics program around the world. Guns and matching optics for
TWTs, Gyrotrons, Accelerators, and many other applications have been
successfully designed and optimized with it. All major laboratories are
using it since decades and it has seen a continuous improvement year by
year. We now have a graphical editor for the input files as well as a
compose program for graphical output files.

Static magnetic
fields
|
|
EGUN and IGUN can include external static magnetic fields for the
calculation of trajectories. INTMAG calculates static magnetic fields by
integration and provides high precision data without the need of
“maxwellization” by COILFIT as other available programs. A very user
friendly interface is provided for the transfer of INTMAG results to
EGN2W and IGUN input files. IGUN then even can plot the magnetic elements
together with the electrostatic ones, eliminating possible errors.

Ion guns and
trajectory optics
|
IGUN, is a child of EGUN and its counterpart for ion extraction
from plasmas. IGUN features interactive coloured graphics and has become a
world standard for the simulation of ion extraction from all kind of ion
sources and their matching to RFQ accelerators.
The new version shows "live" graphics under all WINDOWS
operating systems (including W-XP)
