3. A.I Magnets: Installation
The installation of the vacuum chambers will be performed in 181 in NormaLam
The quadrupoles, H/V correctors, sextupoles, TL bending need to be opened for the installation of the vacuum chambers.
Solenoid and bending magnet vacuum chamber can be slided into the magnet
The vacuum chambers can be delivered directly to 181 (Maxime Dumas) once they are ready.

7. Magnets: H/V corrector
To avoid all hysteresis effect an iron-free design was proposed and designed.
Indirect cooling concept.
Prototype was manufactured at CERN.
Magnetic measurements were performed and small modification were applied to the design.

11. B.I Magnets: Materials delivered by CERN
All auxiliary material is either delivered or ready for delivery.
Mandrels for corrector parts are produced after the pre-series is produced to be able to implement small changes into the design.
Daniel Schoerling TE-MSC-MNC

12. C.I Magnetic Measurements
Fluxmeter
Quadrupoles, correctors, sextupoles and TL dipole will be measured with dedicated rotating coil measurement equipment.
Measurement equipment for ELENA ring dipole magnet is ongoing.
Option 1: PCB under development with Elvia FR
Option 2: Litz-wire fluxmeter was constructed at CERN
Best option is the PCB. Two options were pursued because it is the first time that such a high sensitivity flux meter for low ramp-rates is built
Two in-house flux meter wound and electrically connected. Calibration and impregnation is on-going.

13. D. IV Conclusion
First magnets ready for installation (TL bending magnet & QPMA).
Other magnets will be ready, with very minor impact on the final overall installation date.
Team of 5 engineers/technicians is ensuring a close follow-up for a timely and high-quality delivery of the magnets.
Team of 2 engineers/technicians performs magnetic measurements
NormaTef is available for performing the certification in a timely manner.
NormaLam is available for performing the installation of the magnets.
