Mechanical stress is avoided at the ends of a high-field solenoid by winding the turns at 45 degrees to the axis of the bobbin, and grading the current loading at the ends. This grading is achieved by making the helical turns 14-19 of the coil of different lengths so that they extend by different extents into the connection areas, the connections between the turns being made by series links 15, 17 &c. The length of these end areas may be up to ten times the radius of the main part of the coil. As shown, the end connections are made at circular metal plates 3-13 and 3<SP>1</SP>-13<SP>1</SP>, and additional layers are wound on top of the winding shown and connected, in parallel, to the plates. The end plates may be divided into sectors, each connected to a winding layer, thus enabling series connection to be made.</p> |
