Study of the parameters affecting ion beam emerging from cold conical cathode ion source

High-brightness Cs focused ion beam from a cold-atomic-beam ion source

We present measurements of focal spot size and brightness in a focused ion beam system utilizing a laser-cooled atomic beam source of Cs ions. Spot sizes as small as (2.1 ± 0.2) nm (one standard deviation) and reduced brightness values as high as (2.4 ± 0.1) × 107 A m-2 Sr-1 eV-1 are observed with a 10 keV beam. This measured brightness is over 24 times higher than the highest brightness observ...

Ion Beam Measurements at the Superconducting ECR Ion Source SECRAL

Development of an Ion Emitter with Hollow Cold Cathode

Ion physics forms the basis for numerous modern technologies and research directions such as microelectronics, material research, analytics or high-energy physics. The reason for the broad range applications of ion physics lies in the ions characteristics: -The ions possess a mass, which makes a direct energy transfer possible to the solid atoms (flexible energy transmission); -The velocity of ...

Implementation of a Superconducting Electron Beam Ion Source into the Hit Ion Source Testbench

Cancer therapy with light heavy ions is now a well proven technology. Almost all facilities are running Electron Cyclotron Resonance Ion Sources (ECRIS) to produce carbon ions and protons as well. In the 1990’s the idea of using a Electron Beam Ion Source (EBIS) was proposed [1]. Some proof of principle measurements were carried out [2] but the application of EBIS ion sources in radiation facil...

Simulation of H- ion source extraction systems for the Spallation Neutron Source with Ion Beam Simulator.

A three-dimensional ion optical code IBSimu, which is being developed at the University of Jyväskylä, features positive and negative ion plasma extraction models and self-consistent space charge calculation. The code has been utilized for modeling the existing extraction system of the H(-) ion source of the Spallation Neutron Source. Simulation results are in good agreement with experimental da...
