NMR shim system

A method for producing a shim system comprising a coil former, an extension tube and a terminal unit, said method comprising:

• a) providing the coil former with a circuit board and wire-holding devices thereon;
• b) connecting a terminal line to one of the wire-holding devices of the coil former;
• c) running the terminal line to an upper end of a partial coil region for partial coils having an uneven number of layers or to a lower end of a partial coil region for partial coils having an even number of layers;
• d) winding a partial coil having one or more layers towards a lower end of the partial coil region that faces the circuit board;
• e) running the terminal line to one of the wire-holding devices;
• f) running the terminal line to a further one of the wire-holding devices for a further partial coil;
• g) repeating steps c) to f) for each additional partial coil and each additional terminal line;
• h) connecting all the terminal lines to the circuit board;
• i) removing the terminal line parts running between the circuit board and the wire-holding devices;
• and
• j) fitting the extension tube and the terminal unit into the shim system and connecting all the terminal lines that run to the circuit board to the terminal unit.
