Description

The 2.45 GHz Electron Cyclotron Resonance Ion
Source (ECRIS) has been indigenously developed.
This development of ECRIS aims to provide high
brightness, stable, and reliable D+ ion beam of 20
mA in continuous (CW) mode operation for
accelerator-based D-T neutron generator. The ECR
ion source setup consists of a microwave system, a
magnet system, a double wall water-cooled plasma
chamber, a high voltage platform, a three-electrode
ion extraction system, and a vacuum system. The
ECR ion source test setup is installed and deuterium
plasma generated. Three-electrode extraction system
is designed and fabricated for the ion beam
extraction. A ~10 mA deuterium ion beam is
extracted from the ECR ion source. The paper covers
the detailed experimental setup of ion beam
characterization and diagnostics used for
measurement of beam profile, beam current, and
beam emittance measurements. It also covers the
latest results of beam profile, and beam current
measurement as a function of extraction voltage, gas
flow, and acceleration voltage.
