3. Magnet design Delay line type magnet, 17 cells 568 mm (width) × 778 mm (height) × 452 mm (length) ~327 kg Ex AA injection kicker Materials • • • Ferrite 8 C 11 304 L frame and conductors Al. Mg 3 plates Al 2 O 3 insulators Inconel 600, Monel 400 Rolling direction Bake-able at 300 °C L. Sermeus TE-ABT-FPS ELENA IIC meeting 3 th April 2014 6

4. Vacuum tank design • Similar to LEIR KFH 31 • Tank Ø ~ 1 m, length 562. 4 mm (flange to flange) • UHV Conflat flanges and Wheeler DN 1000 made of circular laminated 316 LN. • All parts made of 316 LN (or 304 L according to availability). • Cover and end will be bowed for a better mechanical stiffness. • The stainless steel parts will be vacuum fired at 950 °C for optimum performances. • DN 150 flange at input, DN 100 at output. • DN 160 at bottom for 400 l/s ion pump. Raw material to be ordered now because of long lead time (~3 months) L. Sermeus TE-ABT-FPS ELENA IIC meeting 3 th April 2014 7

4. Vacuum tank design NEG coating? No solenoid available to coat a Ø 1000 tank Proposed solution: coated plates distributed around the tank circumference and on the sides L. Sermeus TE-ABT-FPS ELENA IIC meeting 3 th April 2014 8

4. Vacuum tank design Survey: two plates for target reference socket cups LHCGIMSA 0003 (green arrows). Tilt flat bar aligned with the magnet aperture will also be provided. Three adjustable feet for positioning in x, y and z directions. External targets aligned with aiming wedges placed inside the magnet aperture. Alignment precision ± 0. 1 mm Lifting and handling: two M 20 threads for eye bolts are placed on top of the tank (red arrows). L. Sermeus TE-ABT-FPS ELENA IIC meeting 3 th April 2014 9

6. Status • Engineering specification published in EDMS. Comments will be taken into account. (LNA-MKKFH-ES-0001) • Drawings of the kicker tank to be checked and follow the CDD approval path. • Raw material (mainly 316 LN) to be ordered as soon as possible. • Tank manufacture in the Cern main workshop during summer for delivery end October 2014. • Installation of new kicker generators platform in B 393 will start soon.
