HIGH RESOLUTION GAS FIELD ION COLUMN
摘要:
An ion beam apparatus and a method for providing an energy-filtered primary ion beam are described. Therein, a primary ion beam having an asymmetric first energy distribution is generated by means of an ion source. The primary ion beam is energy filtered using, for example, a retarding lens.
