Abstract:
1. A system for processing an object, the system comprising: a gas supply apparatus for supplying gas to the object; a beam source for generating at least one activation beam for activating the gas; and a beam optics for directing the at least one activation beam to the object, wherein the gas supply apparatus comprises a stack of a plurality of plates, being adjoined via their flat sides extending transverse to a beam direction of the activation beam, wherein the stack of plates allows traversal of the activation beam towards the object and wherein the stack of plates comprises at least one gas inlet and at least one gas outlet which gas outlet is arranged in a flat side of a plate of the stack which plate is arranged closest to the object, wherein the gas inlet and the gas outlet are connected with each other by a conduit system formed in the stack which conduit system comprises at least one conduit section extending from a location in the stack remote from a location of the traversal of the activation beam to a location close to the location of the traversal of the activation beam, wherein the gas supply apparatus further comprises a tempering apparatus inside the stack of plates for at least one of cooling and heating gas contained in the gas conduit system.
