Ion sources for ion machining applications

12th International Electric Propulsion Conference, 1976
Ion sources with beam diameters of 2.5, 10, and 20 cm have been developed for ion machining applications. All three of these sources use carbon grids to minimize accelerator grid sputtering. A new starting circuit Is also employed that uses only passive components for initiation of the discharge. The two larger sources use a flat multipole chamber with

A Magnetic Ion Source

Review of Scientific Instruments, 1949
An ion source for particle accelerators is described. The ion source utilizes an axial magnetic field for collimation of ion and electron beams and provides an electric field-free region for ion formation. The ion source has afforded yields of 500 microamperes of resolved protons when used in conjunction with a 200-kv high voltage set. A feature of the

Linac4 H− ion sources

Review of Scientific Instruments, 2015
CERN’s 160 MeV H− linear accelerator (Linac4) is a key constituent of the injector chain upgrade of the Large Hadron Collider that is being installed and commissioned. A cesiated surface ion source prototype is being tested and has delivered a beam intensity of 45 mA within an emittance of 0.3 π ⋅ mm ⋅ mrad.

A POSITIVE ION SOURCE

Canadian Journal of Research, 1948
Positive ions are formed in a low pressure electrodeless discharge which is excited by the radio-frequency field of a coil coupled to a 15 Mc. per sec. oscillator. The ions are extracted from the discharge through a pumping canal (2 mm. in diameter × 12 mm. in length) by a simple arrangement of electrodes. After further focusing and acceleration to 50
