A low power low cost 2.45 GHz ECRIS for the production of multiply charged ions

A low cost, low power ECR ion source designed for the use on a high voltage platform with limited electrical power available, has been developed. To reduce the power consumption of the source the radial and axial magnetic confinement are produced entirely by permanent magnets. An axial magnetic mirror ratio of 2.7 is obtained by a configuration of two times four block magnets. A radial magnetic field of 0.5 T inside the plasma chamber of 60 mm inner diameter is produced by a hexapole magnet. Mi… more

Characterization and recent modification of a compact 10 GHz ECRIS for atomic physics experiments and spectroscopic investigations

A compact 10 ECR ion source (200 mm long, 170 mm diameter) has been developed and tested. The complete magnetic structure made from permanent magnet material is comprised of four ring magnets producing an asymmetric axial magnetic field and a hexapole magnet with a maximum radial field of 0.94 T inside the plasma chamber. The coupling of the microwave to the plasma shows efficient ECR plasma heating at microwave power levels around 10 watts. Charge state distributions for various elements with … more

A new 14 GHz Electron-Cyclotron-Resonance Ion Source (ECRIS) for the heavy ion accelerator facility ATLAS

A 14 GHz Electron-Cyclotron-Resonance Ion Source (ECRIS) has been designed and built at Argonne National Laboratory. The source is a modification of the AECR at Berkeley and incorporates the latest results from ECR developments to produce intense beams of highly charged ions, including an improved magnetic confinement of the plasma electrons with an axial mirror ratio of 3.5. The aluminum plasma chamber and extraction electrode as well as a biased disk on axis at the microwave injection side do… more

A new 14 GHz electron-cyclotron-resonance ion source (ECRIS) for the heavy ion accelerator facility ATLAS: a status report

A new 14 GHz ECRIS has been designed and built over the last 2 years. The source, a modification of the Berkeley AECR, incorporates the latest results from ECR developments to produce intense beams of highly charged ions, i.e., an improved electron confinement with an axial magnetic mirror ratio of 3.5 and a radial magnetic field inside the plasma chamber of 1.0 T. The aluminium plasma chamber and extraction electrode as well as a biased disk on axis at the microwave injection side donate addit… more

A new 14 GH{sub z} electron-cyclotron-resonance ion source (ECRIS) for the heavy ion accelerator facility ATLAS

A new 14 GHz ECRIS has been designed and built over the last two years. The source design incorporates the latest results from ECR developments to produce intense beams of highly charged ions. An improved magnetic electron confinement is achieved from a large mirror ratio and strong hexapole field. The aluminum plasma chamber and extraction electrode as well as a biased disk on axis at the microwave injection side donate additional electrons to the plasma, making use of the large secondary elec… more

An ultra compact 10 GHz electron-cyclotron-resonance ion source (ECRIS) for the production of multiply charged ions

There is a growing interest in the use of beams of multiply charged ions produced in special environments like high voltage platforms, Dynamitrons, Van-de-Graaff accelerators or on-line production systems for radioactive beam facilities. A compact 10 GHz ECR ion source (200 mm long, 170 mm diameter) has been developed and tested. The complete magnetic structure made from permanent magnet material is comprised of four ring magnets producing an asymmetric axial magnetic field with a mirror ratio … more
