PIG-Type Compact Microwave Metal Ion Source

Abstract
A compact microwave metal ion source using PIG (Penning lonization Gauge) geometry has been newly developed. This modified PIG ion source introduces a microwave discharge and can generate stable and high density plasma. The size of the source is 60 mm in diameter and 80 mm long. The microwave discharge power is 20∼60 W at a frequency of 2.45 GHz. A tantulum ion beam current of 3.2 µA has been measured with the extraction aperture (2 mm diameter) at an extraction voltage of 13 kV.
