Abstract:
1. A particle beam system comprising: a charged particle beam source configured to generate a charged particle beam; a beam blanking module connectable to a data network, the beam blanking module configured to blank and un-blank the charged particle beam; a focusing lens configured to focus the charged particle beam onto an object; a first beam deflection module connectable to the data network, the first beam deflection module configured to deflect the beam; a calculation module configured to determine a deflection time, a deflection amount, an un-blank time and a blank time, the calculation module being configured to generate a data structure comprising a plurality of data records, each data record comprising a command representing an instruction for at least one of the first beam deflection module and the beam blanking module, each data record comprising a command time representing a time at which the instruction is to be sent to the data network, the calculation module being configured to sort the data records by command time; and an encoding module configured to generate a set of digital command data encoding the commands included in the data records, the encoding module configured to send the generated digital command data to the data network in an order corresponding to an order of the sorted records.
