Report

The longitudinal energy spread of ion beams extracted from an electron cyclotron resonance ion source

Autor: Angot, Julien, Tarvainen, Olli, Chauveau, Pierre, Kosonen, Sami, Kalvas, Taneli, Thuillier, Thomas, Migliore, Myriam, Maunoury, Laurent

We present a study of factors affecting the energy spread of ion beams extracted from a Charge Breeder Electron Cyclotron Resonance Ion Source (CB-ECRIS). The comprehensive simulations, supported by experiments with a Retarding Field Analyser (RFA),

Report

Measurement of the energy distribution of electrons escaping minimum-B ECR plasmas

Autor: Izotov, Ivan, Tarvainen, Olli, Skalyga, Vadim, Mansfeld, Dmitry, Kalvas, Taneli, Koivisto, Hannu, Kronholm, Risto

The measurement of the electron energy distribution (EED) of electrons escaping axially from a minimum-B electron cyclotron resonance ion source (ECRIS) is reported. The experimental data were recorded with a room-temperature 14 GHz ECRIS at the JYFL

Photoelectron Emission from Metal Surfaces Induced by Radiation Emitted by a 14 GHz Electron Cyclotron Resonance Ion Source

Autor: Laulainen, Janne, Kalvas, Taneli, Koivisto, Hannu, Komppula, Jani, Kronholm, Risto, Tarvainen, Olli

Photoelectron emission measurements have been performed using a room-temperature 14 GHz ECR ion source. It is shown that the photoelectron emission from Al, Cu, and stainless steel (SAE 304) surfaces, which are common plasma chamber materials, is pre

E-sail test payload of ESTCube-1 nanosatellite

The scientific mission of ESTCube-1, launched in May 2013, is to measure the Electric solar wind sail (E-sail) force in orbit. The experiment is planned to push forward the development of E-sail, a propulsion method recently invented at the Finnish M
