Title: Engineering Sheets of 12 Metre Solenoid

The solenoid design follows closely the considerations qiven in {bar p} note 116. In particular we try to make the solenoid undivided, but with a centre tap for the cooling water. We found a variant for the centre tap, so that the two layers are now electrically in series. Due to the very long length, it seems better not to fill the clearance between return yoke and OD of the second layer with epoxy. Instead, we support and adjust the coil every 2 m with three bolts at 120 deqrees screwed in the return yoke. The latter is then supposed to be sufficiently stiff, so as to give the weaker mandrel the desired straightness. We give a positive pitch, i.e. somewhat more than the width of the copper section including insulation and tolerances. The precise pitch cannot be stated here, because the copper section will be somewhat trapezoidal. How much, depends on the winding procedure. The layers are epoxy impregnated and solidair with the mandrel. The Figures show an axial section and the construction of the central water tap. The dimensions shown are on the assumption of a free choice of the diameters of return yoke and mandrel. This may not be the case, and a reshuffling of the dimensions may be needed.
