DRAFT • Pressure Test of the helium process volume has be checked with a pressure 1.4 times higher than the design pressure. • Quench Heater Test – some of the SIS100 (6) quadrupoles are equipped with a quench heaters; the quench heaters have to be powered and the proper current and voltage curves have to be achieved. • Warm Magnetic Measurement – is described below • Vacuum Chamber Test – is described in related chapter, • Geometry Test – is described in related chapter. Warm Magnetic Measurement Apart from insulation, electrical and geometric tests, magnetic measurements allow to monitor the quality of the production. The field quality of iron dominated magnets is mainly determined by the shape of the iron pole, thus the field quality can only be tested when operating at nominal conditions. Thus only the geometry of the iron is controlled during the production. Additionally a check of the coil has to be foreseen before assembling them with the iron yoke. 2.4.A5.3.2 Site Acceptance Tests The Site Acceptance Tests (SAT), as the final acceptance test, includes results of FAT and all tests done at GSI and the final evaluation of the test results. The value, parameters, conditions and compatibility of the SAT tests will be specified during the Final <strong>Design</strong> Review unless they have been previously specified in the <strong>Technical</strong> Specification. The SAT includes 3 main stages which shall assure the quality of the magnet. The magnet can be rejected after each stage of the SAT procedure and sent back to the manufacturer for reparation or replacement. Stage 1 - Reception Tests After delivery each individual superconducting magnet has to pass a reception test at warm. In principle all reception tests have to confirm the FAT tests. If the magnet does not fulfil the criteria of the Reception Tests, it will be tested at Operation Temperature and will be sent back to the manufacturer for reparation. As an example the following reception test is shown below: 1. Electrical Tests: • Insulation Tests. • Resistance and Inductance Tests. • Continuity and Instrumentation Tests. 2. Vacuum leakage and pressure tests • Vacuum Test of the cryostat – the results has to show a leak rate better than 10 -8 mbar/s. • Vacuum Test of the helium process lines – the results has to show a leak rate better than 10 -8 mbar/s. • Pressure Test of the helium process volume has be checked with a pressure 1.4 times higher than the design pressure. 196
DRAFT 3. Geometry tests For cryostated magnets the geometry of the bore and the position of reference surfaces on the cold mass are measured with respect to the fiducials of the cryostat. Stage 2 - Tests at Operation Temperature All magnets have to be tested in operating conditions to warrant the full functionality, as testing is considered cheaper than identifying a troublemaker in the ring and having it repaired. During the tests all safety parameters and requirements have to be checked and fulfilled not to risk to loose a magnet during the power test (e. g. a coil to coil short burning the conductors of the magnet). After all tests at operating temperature have been performed, the preliminary evaluation of the test results has to be done. The main steps of the tests performed at the operating temperature are outlined in the following: 1. Tests before Cooling Down • Insulation Tests. • Vacuum and Leakage Tests • Check of purity of the helium process gas • Resistance and Inductance Tests. • Continuity and Instrumentation Tests. 2. Tests before Power Test at cold • Insulation Tests. • Vacuum and Leakage Tests • Continuity and Instrumentation Tests. 3. Power Test • Training the magnet up to the nominal current - First Thermal Cycle Criterion • 'Fast' excitation and de-excitation • Training during the second thermal-cycle if the First Thermal Cycle Criterion is not fulfilled - Second Thermal Cycle Criterion • measurement of the resistance of all joints in the magnet • Temperature margin • AC and DC losses measurements • Vacuum and Leakage Tests during all measurements 4. Cold Magnetic Measurements • ∫ Bdl , ∫ Gdl , harmonics, axis • Field at DC at least at injection, maximum field and at the geometrical middle • For ramped magnets (SIS 100 / SIS 300) also the AC components 5. Tests after Power Test at cold • Insulation Tests. • Continuity and Instrumentation Tests. 6. Test after Warming Up • Insulation Tests. 197
