Cs evaporation in a negative ion source and Cs cleaning tests by plasma sputtering
M. Barbisan, R. S. Delogu, A. Pimazzoni +3
The compact radio frequency negative ion source NIO1 (Negative Ion Optimization phase 1) has been designed, built and operated by Consorzio RFX and INFN-LNL in order to study and o…
Lessons learned after three years of SPIDER operation and the first MITICA integrated tests
D. Marcuzzi, V. Toigo, M. Boldrin +139
ITER envisages the use of two heating neutral beam injectors plus an optional one as part of the auxiliary heating and current drive system. The 16.5 MW expected neutral beam power…
Continuous pulse advances in the negative ion source NIO1
M. Barbisan, R. Agnello, M. Cavenago +23
Consorzio RFX and INFN-LNL have designed, built and operated the compact radiofrequency negative ion source NIO1 (Negative Ion Optimization phase 1) with the aim of studying the pr…
First Beam Characterization by Means of Emission Spectroscopy in the NIO1 Experiment
M. Barbisan, B. Zaniol, M. Cavenago +2
The NIO1 experiment hosts a flexible RF H- ion source, developed by INFN-LNL and Consorzio RFX to improve the present concepts for the production and acceleration of negative ions.…
Electron Density and Temperature in NIO1 RF Source Operated in Oxygen and Argon
M. Barbisan, B. Zaniol, M. Cavenago +3
The NIO1 experiment, built and operated at Consorzio RFX, hosts an RF negative ion source, from which it is possible to produce a beam of maximum 130 mA in H- ions, accelerated up…
First hydrogen operation of NIO1: characterization of the source plasma by means of an optical emission spectroscopy diagnostic
M. Barbisan, C. Baltador, B. Zaniol +6
NIO1 is a compact and flexible radiofrequency H- ion source, developed by Consorzio RFX and INFN-LNL. Aim of the experimentation on NIO1 is the optimization of both the production…
Modeling and design of a BES diagnostic for the negative ion source NIO1
M. Barbisan, B. Zaniol, M. Cavenago +1
Consorzio RFX and INFN-LNL are building a flexible small ion source (NIO1) capable of producing about 130 mA of H- ions accelerated at 60 KeV. Aim of the experiment is to test and…
Ion resonance instability in the Eltrap electron plasma
Giovanni Bettega, Francesco Cavaliere, Marco Cavenago +3
A small fraction of ions can destabilize the diocotron mode (off axis rotation) of an electron plasma confined in a Malmberg-Penning trap. In this paper a set of experimental measu…
Coherent structures in an electron beam
Andrea Illiberi, Giovanni Bettega, Marco Cavenago +4
The formation and evolution of coherent structures in a low-energy electron beam produced in a Malmberg-Penning trap is investigated by means of CCD diagnostics. The electrons are…
