Experimental study demonstrates accurate geometric control of deep-drilled cooling channels in ITER diagnostic ports using a laser tracker, indicating reliable quality assurance for fusion reactor...
The article describes a method for controlling the geometric parameters of the cooling system channels of the diagnostic shielding modules of the equatorial port no. 11 of the ITER nuclear installation made using counter deep drilling technology. The technique is based on the use of an angular reflector moving through the test channel and a laser tracker. The results of the qualification of the methodology on a full-size test product modeling the deepest channels in the diagnostic shielding module are presented.
