Isis Ion Source Operational Experience
The ISIS ion source is a surface plasma ion source of the Penning type, and routinely produces 35 mA of H ions during a 200 μs pulse at 50 Hz for uninterrupted periods of up to 40 days. A new computer control system was installed in 1995, which, in addition to providing much tighter control of ion source parameters, has allowed these parameters to be logged every fifteen minutes and then averag...
متن کاملInitial study of the optical spectrum of the ISIS H- ion source plasma.
The front end test stand is being constructed at the Rutherford Appleton Laboratory, with the aim of producing a 60 mA, 2 ms, 50 Hz, perfectly chopped H(-) ion beam. To meet the beam requirements, a more detailed understanding of the ion source plasma is required. To this end, an initial study is made of the optical spectrum of the plasma using a digital spectrometer. The atomic and molecular e...
متن کاملPlasma meniscus and extraction electrode studies of the ISIS H- ion source.
In order to reduce the emittance and increase the transported beam current from the ISIS Penning-type H(-) ion source, improvements to the extraction system are required. This ion source is currently being commissioned on the front end test stand at the Rutherford Appleton Laboratory, which demands higher extraction energies, higher beam currents, and smaller emittances. To facilitate this, the...
متن کاملBernas ion source discharge simulation.
As the technology and applications continue to grow up, the development of plasma and ion sources with clearly specified characteristic is required. Therefore comprehensive numerical studies at the project stage are the key point for ion implantation source manufacturing (especially for low energy implantation). Recently the most commonly encountered numerical approach is the Monte Carlo partic...
متن کاملSpark discharge coupled laser multicharged ion source.
A spark discharge is coupled to a laser multicharged ion source to enhance ion generation. The laser plasma triggers a spark discharge with electrodes located in front of the ablated target. For an aluminum target, the spark discharge results in significant enhancement in the generation of multicharged ions along with higher charge states than observed with the laser source alone. When a Nd:YAG...
