METHOD OF MAKING MULTICAPILLARY COLLIMATOR FOR ATOMIC BEAM TUBE Russian patent published in 2013 - IPC G21K1/02 

FIELD: physics.

SUBSTANCE: method of making a multicapillary collimator for an atomic beam tube involves making perforated metal plates, assembling said plates into a stack and fixing. Said plates are made by electro-forming techniques. Stacking is carried out by sign-matching two or more plates with a transparent polymer, primarily a photoresist, placed in between said plates. The plates are fixed after polymerisation of said polymer by welding each plate with neighbouring plates, after which the polymer is removed and a metal layer is grown by chemical deposition on the surface of the assembly, including the inner surface of through-openings which form capillaries. Plates can be welded to neighbouring plates on two ends inside matching signs on a split-tip welding machine. The polymer is removed by plasma-chemical etching.

EFFECT: making a collimator with capillaries of the required diameter and number with optimum distance in between and improved vertical position thereof and quality of the inner surface.
