Magnet design Rolling direction Delay line type magnet, 17 cells 568 mm (width) × 778 mm (height) × 452 mm (length) ~327 kg Ex AA injection kicker Materials Ferrite 8C11 304L frame and conductors AlMg 3 plates Al 2 O 3 insulators Inconel 600, Monel 400 Bake-able at 300 °C

7. L. Sermeus TE-ABT-FPSELENA IIC meeting 3 th April 20147 4. Vacuum tank design Similar to LEIR KFH31 Tank Ø ~ 1 m, length 562.4 mm (flange to flange) UHV Conflat flanges and Wheeler DN1000 made of circular laminated 316LN. All parts made of 316LN (or 304L 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. DN150 flange at input, DN100 at output. DN160 at bottom for 400 l/s ion pump. Raw material to be ordered now because of long lead time (~3 months)

8. L. Sermeus TE-ABT-FPSELENA IIC meeting 3 th April 20148 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

9. L. Sermeus TE-ABT-FPSELENA IIC meeting 3 th April 20149 4. Vacuum tank design Survey: two plates for target reference socket cups LHCGIMSA0003 (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 M20 threads for eye bolts are placed on top of the tank (red arrows).

(LNA-MKKFH-ES-0001) Drawings of the kicker tank to be checked and follow the CDD approval path. Raw material (mainly 316LN) 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 B393 will start soon.
