Abstract:
A system for in situ controlling the operational parameters of a radio frequency (RF) linear accelerator (linac) (23) in an ion implanter (1), comprising:(i) a user input device (10) for accepting from a user numeric value calculation codes and data representing necessary operational conditions of the linac;(ii) a control calculation device (11) for (a) storing the numeric value calculation codes and the data representing necessary operational conditions, (b) calculating one or more operational parameters for the linac based on said numeric value calculation codes and said data; and (c) outputting one or more control signals; said control calculation device including means for simulating the acceleration or deceleration of an ion beam based on said numeric value calculation codes and said data, and for automatically calculating at least one of said operational parameters and outputting at least one of said control signals; and(iii) control devices (12, 13, 14) for receiving said one or more control signals and, in response thereto, controlling said operational parameters of the linac (23).
