Development, fabrication, and assembly of a thin wall, low aspect ratio liner and the enclosed tungsten limiter for ORMAK

Conference ·
OSTI ID:4403753
From 5th symposium on engineering problems of fusion research; Princeton, New Jersey, USA (6 Nov 1973). The regiine in which a Tokamak operates depends largely on the amount of impurities present. To keep the plasma as pure as possible, the plasma region is surrounded by a thin but vacuumtight stainless steel liner. The ORMAK liner is a stainless steel torus having a major radius of 315/16 inches and a minor radius of 97/8 inches. Wall thickness of the liner is 10 mils. The liner consists of 26 sections welded together to form two halves plus two special sections. These special sections contain the limiter and laser ports. The two special sections are also used to make the final closure of the liner after it has been placed inside the aluminum torus. The liner contains 53 diagnostic ports and 4 injection beam ports.
