Efremov Institute Cooperation 13 Efremov Institute Cooperation Many years Efremov Institute works in cooperation with European physical centers (e.g. GSI and DESY) in the field of design, engineering and manufacture of different electromagnets for accelerating facilities and experimental physical equipment.

Efremov Institute Cooperation 14 Efremov Institute Cooperation Cooperation with GSI In 1990 the magnet yoke for the 4π detector by weight of 100 t for the SIS/ESR project was manufactured and delivered. In 1997 5 dipole magnets (14,5° and 7,5°) for the HADES Experiment were manufactured and delivered. In 2003 2 dipole magnets (7,5°) for the beam line from SIS accelerator to the HHT experimental area were manufactured and delivered. In 2000-2001 2 quadrupole magnets of the spectrometer VAMOS designed by GSI were manufactured and delivered to GANIL, Caen, France.

Manufacturing of magnet yokes The laminated dipole magnet yokes are produced from magnetic steel ones from 1-mm-thick steel sheet of "Power Core 1200-100A" type (DIN EN 10106-02/1996) covered with Stabolit 70 on both sides. The quadrupole magnet yokes consists of laminated iron quadrants produced from 1-mm-thick steel sheet of "Power Core 1200-100A" type (DIN EN 10106-02/1996) covered with Stabolit 70 on both sides. All magnets can be easily deassembled in the horizontal plane for subsequent installation of the vacuum chamber.

Requirement to magnet coils The conductor for all coils should be made of oxygen-free electrolytic copper (OF-Cu according to DIN 1787) with a specific resistance not exceeding 1.72 x 10-8 Ω×m at 20°C. The coils should behave as rigid bodies with mechanical strength sufficient to withstand the electromagnetic forces and thermal stresses (which can occur cyclically) without developing cracks. All conductor parts should be insulated and impregnated with waterproof compound free of entrapped air. Electric strength of insulation between the conductors and the yoke should be tested at an effective voltage of 1.5 kV at 50 Hz applied for 1 minute. One of the coils produced (for each type of magnet) is to be subjected to 500 thermal cycles between 30 °C and 60 °C and after thermocycling tested before the series production continues.

Manufacturing of magnet coils

Manufacturing of Magnet XBB for XFEL project All 14 XBB magnets are manufactured. Six of them have been measured. One of them is now at DESY for verifying results of the magnetic measurements, which have been done at the Efremov Institute. Homogeneity of magnetic field in the XBB should be about 1×10-4. So, to reach this accuracy magnetic calculations for the pole profile were required. Magnetic testing Special partial disassembling

Manufacturing of Magnet Type XQF (90 pieces) for XFEL project Three magnets has been assembled. For this quadrupoles the magnetic measurements have been carried out. The measurement results are analyzed now by specialists of DESY and Efremov Institute.

Manufacturing of Magnet Type XQH (35 pieces) for XFEL project Three magnets has been assembled.

Manufacturing of Magnet Type XQE (43 pieces) for XFEL project 16 quadrupole magnets XQE are manufactured. For 15 magnets the magnetic measurements have been carried out. Now the measurement results are analyzed by DESY and Efremov Institute specialists.
