Abstract:
A target grid assembly for employment in a target assembly used to produce radioisotopes by bombarding a target material contained in the target assembly with a particle beam, the target assembly further including a target body defining a target reservoir for receiving the target material and a target window for sealing the target reservoir, said target grid assembly comprising:a vacuum window; a target grid defining a target grid portion, a helium input and a helium output, said target grid portion defining a plurality of target grid supports which are configured to form a plurality of target grid oblong openings, said target grid portion defining an upstream side and a downstream side, said vacuum window being positioned against said upstream side, the target window being supported between said downstream side and the target body, a helium space being defined by said plurality of target grid oblong openings between said vacuum window and the target window and being configured such that helium is injectable into said helium space via said helium input and extractable from said helium space via said helium output; and an interception grid positioned upstream of said vacuum window, said interception grid defining an interception grid portion which defines a plurality of interception grid supports, said interception grid supports being configured to form a plurality of interception grid oblong openings, said vacuum window being positioned between said interception grid supports and said target grid supports.
