Magnet Type QPMA • All information on this magnet gathered on: http: //normadb. web. cern. ch/cern_norma/magdesign /idcard/? id=270#1 • Four magnets of this type are ordered • One of the spare magnets can be used for the AD-ELENA transfer line Daniel Schoerling Design Type PXMQNAFNWP Description Quadrupole magnet type QPMA Cooling system Water Aperture diameters 60. 0 mm Iron Length 200. 0 mm Total Length 300. 0 mm Total Width 350. 0 mm Total Height 440. 0 mm Weight 100 Kg Peak Current (cycled) 200. 0 A RMS Current 200. 0 A Resistance 20°C 46. 2 m Inductance 3. 2 m.

ELENA ring quadrupole • Manufacturing of 3 additional ELENA ring quadrupole magnets for the TL (total 12 (ring) + 3 (TL) + 1 (spare) • Main magnetic parameters of the ELENA ring quadrupole: Description Cooling Value Unit Air Integrated strength 0. 36 T Field gradient 1. 50 T/m Magnetic length 242. 1 mm Aperture diameter 124 mm Good field region (GFR) 54 mm diameter Field quality 5 x 10 -4 Overall width / height 480 mm Overall length 270 mm Overall mass 200 kg Daniel Schoerling Design by L. Vanherpe TE-MSC-MNC 5

Conclusions Quadrupole • No additional magnet design is required and having only two magnets types reduces number of required spare magnets • ELENA ring dipole magnet do not have to be adapted to meet the integrated field gradient requirements of the AD-ELENA line • ELENA quadrupole magnets can be air cooled • QPMA will be soon delivered to CERN • Design of ELENA ring quadrupole is almost finished • Decision of this ELENA ILC meeting will be fixed in minutes and the change of the number of required magnets will be added as addendum to the functional specification Other magnets of TL • BM 1 and BM 2 final discussion on-going, decision if powered in series or in two independent circuits is pending! • How many H/V correctors are required for the TL?
