Abstract
Abstract A method for constructing a superconducting magnet winding which contains parallel winding layers each spaced by a separator and around the outer surface of which hardenable material is cast which is worked to a predetermined dimension after hardening, in which each winding layer is prefabricated individually and its outer surface is provided with a cast, ridge-like extension of hardenable material, and in which all cast extensions are worked down to the fit dimension after the winding is assembled, avoiding cementing of cooling ducts together in the separators.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
116 words
A method for constructing a superconducting magnet winding which contains several winding layers which are arranged parallel to each other with a separator of insulating material forming cooling ducts inserted between each two layers, and which winding is surrounded, at least at parts of its outer surface, by hardenable material which is worked down to a predetermined dimension after the hardening process, comprising: (a) individually prefabricating each winding layer with an outer surface having a ridge shaped cast extension of the hardenable material; (b) assembling said winding layers with spacers therebetween into a magnet winding; and (c) working the cast extensions of all winding layers down to the predetermined dimension after the entire winding is assembled.
Claim 2
Independent Claim
116 words
A method for constructing a superconducting magnet winding which contains several winding layers which are arranged parallel to each other with a separator of insulating material forming cooling ducts inserted between each two layers, and which winding is surrounded, at least at parts of its outer surface, by hardenable material which is worked down to a predetermined dimension after the hardening process, comprising: (a) individually prefabricating each winding layer with an outer surface having a ridge shaped cast extension of the hardenable material; (b) assembling said winding layers with spacers therebetween into a magnet winding; and (c) working the cast extensions of all winding layers down to the predetermined dimension after the entire winding is assembled.
Claim 3
Dependent Claim
35 words
The method according to claim 1 and further including, before the assembled winding is worked down, inserting individual separators with a thickness which corresponds to the thickness of the corresponding spacer between adjacent cast extensions.
Claim 4
Dependent Claim
16 words
