MEDeGUN commissioning results / Breitenfeldt, M (CERN) ; di Lorenzo, F (CERN) ; Pikin, A (Brookhaven Natl. Lab.) ; Pitters, J (CERN) ; Wenander, F (CERN)
MEDeGUN [1] is an electron gun to be used in an Electron Beam Ion Source (EBIS) designed to serve as C6+ source for LINAC-based 2nd generation hadron therapy facilities [2]. The latter require short pulses of at least 1*108 particles at a repetition rate of 400 Hz, which exceeds the possibilities of currently used electron cyclotron resonance ion sources (ECRIS) and EBISes. [...]

High Frequency RFQ Design and LEBT Matching for the CERN TwinEBIS Ion Source / Bencini, Vittorio (CERN) ; Breitenfeldt, Martin (CERN) ; Lallement, Jean-Baptiste (CERN) ; Lombardi, Alessandra (CERN) ; Pahl, Hannes (CERN) ; Pikin, Alexander (CERN) ; Pitters, Johanna (CERN) ; Wenander, Fredrik (CERN)
An Electron Beam Ion Source (EBIS) is being developed at CERN for production of highly charged ions, for instance fully stripped $^{12}$C. The focus has so far been on the electron gun design, aiming for a high current compression, which results in a rapid ionisation process and thereby high repetition rate. [...]

First test of BNL electron beam ion source with high current density electron beam / Pikin, Alexander (Brookhaven Natl. Lab.) ; Alessi, James G (Brookhaven Natl. Lab.) ; Beebe, Edward N (Brookhaven Natl. Lab.) ; Shornikov, Andrey (CERN) ; Mertzig, Robert (CERN) ; Wenander, Fredrik (CERN) ; Scrivens, Richard (CERN)
A new electron gun with electrostatic compression has been installed at the Electron BeamIon Source (EBIS) Test Stand at BNL. This is a collaborative effort by BNL and CERN teams with a common goal to study an EBIS with electron beam current up to 10 A, current density up to 10,000 A/cm2 and energy more than 50 keV. [...]

A high-compression electron gun for C$^{6+}$ production: concept, simulations and mechanical design / Mertzig, Robert (CERN ; Dresden, Tech. U.) ; Breitenfeldt, M (CERN) ; Mathot, S (CERN) ; Pitters, J (CERN ; TU Vienna) ; Shornikov, A (U. Manchester (main) ; GANIL) ; Wenander, F (CERN)
In this paper we report on simulations and the mechanical design of a high-compression electron gun for an Electron Beam Ion Source (EBIS) dedicated for production of high intensity and high repetition rate pulses of bare carbon ions for injection into linac-based hadron therapy facilities. The gun is presently under construction at CERN to be retrofitted into the TwinEBIS test bench for experimental studies. [...]

A low energy ion beamline for TwinEBIS / Pahl, H (CERN ; Heidelberg U.) ; Bencini, V (CERN ; INFN, Rome ; Rome U.) ; Breitenfeldt, M (CERN ; ADAM, Geneva) ; Granadeiro Costa, A R (CERN ; IST, Lisbon (main)) ; Pikin, A (CERN ; Brookhaven Natl. Lab.) ; Pitters, J (CERN) ; Wenander, F (CERN)
A low energy beamline has been designed for the TwinEBIS setup. The beamline will be used to transport ions extracted from the electron beam ion source into an accelerating radio frequency quadrupole or into secondary devices, like a time of flight-mass spectrometer, attached to the beamline via a fast three way 20° ion switchyard.
