2.4.A5.2 Conventional Magnets DRAFT Preparative tests of normal conducting magnets, such as insulation test, cooling water flow, etc., are part of the factory acceptance tests (see section 2.4.A5.2.1) of each individual magnet and are not considered as part of the site acceptance test. Thus magnetic measurement is the main measurement task to perform for normal conducting magnets. Special consideration is required if cold-warm transitions in the beamline are necessary (e.g. for injection and extraction of the synchrotrons). The measurement methods applied to the main magnet types are given in Table 2.4.41. 2.4.A5.2.1 Factory Acceptance Tests Samples for BH Curves They have to be provided by the manufacturer. These will be used to assert that the properties of the steel match the specification. If possible, the manufacturer should also measure these samples. Yoke Packing Factor The dipoles and quadrupoles of this ring are made of laminated steel. Thus the packing factor has to be measured for the whole magnet or at least for all its individual packs. Pole geometry The field quality is mainly formed by the shape of the pole. Thus the shape of the pole itself as well as the position of one pole to the other(s) has to be measured. Electrical Safety The magnet producer will have to ensure the save electrical operation of the magnet. As part of this requirement the insulation of the coils and connections has to be tested up to a voltage Vmax of (Vmax = 2 Vop + 1000 V) with Vop the maximum operational voltage in the branch of the machine, where this magnet is to be connected. This test is typically conducted immersing the coil in water and filling the cooling channels of the coil with water at the maximum acceptable pressure level. Interlock systems The water flow and the water temperature through the magnets will be monitored by the machine safety system. Therefore flow and temperature interlocks have to be installed at the water inlet and outlet. Magnetic Measurement of main magnets Machine operation requires precise data of the field of the magnet for the main magnets. The magnetic field of dipoles and quadrupoles has to be measured at: • injection field, • mid field, • maximum field, for DC operation. If the magnets are also ramped quickly, measurements have to be performed which allow to estimate the field strength and the field quality for the whole operation cycle with sufficient accuracy. 192
DRAFT For magnets with less stringent field quality requirements (e.g. correctors and steerer magnets whose field has only to be known in the range of a percent) it is sufficient to monitor the production randomly by measuring only one or few magnets (see also section 2.4.A5.1). The different measurement methods foreseen for the different magnets are summarized in Table 2.4.41. The curvature of the used search coils for the dipoles is given in Table 2.4.42 and the radius of the rotating coil is given in Table 2.4.43. Matching Magnet Length For machines with only a few dipoles and quadrupoles (e.g. 24 pieces) the length of the magnets has to be matched. For this purpose laminations are inserted at the end of the yoke. The field of the magnet has to be remeasured after this operation.
