Magnet vacuum Nuclotrons with LHe flow DRAFT Figure 2.4.157: possible termination of the cold electrical connection. The heat load for the cold electrical connection consists of two main parts, heat conduction from the outside and AC losses in the cable. The heat conduction to the 4.4 K level will be of 80 mW/m for 7 cables and 100 mW/m for 19 cables. The heat inleak to the outer shielding gas with a temperature difference from room temperature to 50 K will be in the range of 1.2 W/m for 7 cables and 1.5 W/m for 19 cables. These data are based on measurements on existing transfer lines with the same design principle. 2.4.A5 Magnet testing 2.4.A5.1 Introduction Line vacuum Line vacuum 50 K He outlet/coupling The FAIR project needs a large number of magnets which have to be produced within a short period of time. To guarantee successful operation of all magnets after installation in the different facilities, a dedicated magnet test program is indispensable covering the following items: 1. quality assurance (production and testing), 2. training the magnets, 3. measurement of the magnetic field, field quality and magnetic axis in case of quadrupoles and higher order multipoles, 4. provide information for operating the magnets, 5. test the quench protection systems for the different machines. The procedure for magnet testing and magnetic measurements is described below. Due to the relatively small number of magnets per series a well established cold-warm correlation for the field quality cannot be assumed in advance. Thus it is assumed that each superconducting magnet has to be trained and measured at operating temperature. 190
DRAFT Measurements planned for each superconducting magnet are: • warm magnetic measurements in industry, • training of the magnet, • power test at different ramp rates for pulsed magnets, • integral loss measurement (voltage-current and calorimetric methods), • magnetic measurements, • insulation and electrical integrity tests, For normal conducting magnets the following measurements have to be performed: • geometry tests in industry • warm magnetic measurement in industry • insulation and electrical integrity tests in industry, • pre-series and special magnet fully tested at the GSI lab Table 2.4.40: Total number of normal and superconducting magnets for <strong>Super</strong>-FRS. All nc magnets are radiation resistant magnets. <strong>Super</strong>-FRS Magnet types no. of magnets nc main magnets (dipoles): 6 nc main magnets (quadrupoles): 3 nc correctors,steeres. 2 nc special magnets (septa, ...) 0 sc main magnets (dipoles and quadrupoles) 28 sc main magnets (dipoles and quadrupoles) 68 sc correctors (mulipole, steering, hexapole,..) 94 Magnetic measurements are performed to ensure the required field and field quality of each individual magnet. The quantities to be measured depend on the type of magnet: • Dipole: o ∫ Bdl , the magnetic field B integrated over the magnet length l o field direction o field quality • Quadrupole: o ∫ Gdl with the magnetic field gradient G integrated over the magnet length l o axis o field direction o field quality • Corrector magnets o dl ∫ Cn with Cn the n th harmonic integrated over the magnet length l o axis o field direction o field quality Ramped magnets must be measured in AC and DC mode. The time delay until the field has stabilized has to be measured for pulsed magnets as well, i.e. magnets which must reach their excitation level during a short time period (in the order of a second). 191
