H/V corrector Production Status

Contract placed Kick-off meeting held Insulated copper ordered (CERN supply via Luvata (FI) and Sofilec (FR))

- Quality issues experienced on products delivered in the past

- New chance given with this contract, to be carefully followed-up

Magnetic Measurements (1/2)

Bent flux-meter development

Magnetic measurement specification discussed with beam optics physicists need longitudinal distribution of the field

Dipole:

– Pre-series: full characterization requires Hall probe 3D mapper (LEP tool to be refurbished)

– Series: integrated field mapping with bent flux-meter

13

Magnetic Measurements (2/2)

Quadrupole:

– Pre-series: need measurement of field gradient in center + longitudinal profile (3D mapping, but few points and small size)

– Series: integrated field harmonics with rotating coil (existing equipment) + fiducialization with stretched wire

H/V correctors:

– Pre-series: measurement of field longitudinal profile (3D mapping, small size) + stray field at several locations (magnetic interference)

– Series: integrated field harmonics with rotating coil (existing equipment), possibly with sampling (one magnet per batch)

Important workload from this project, can be quite challenging in terms of resources

14

Magnet production– All contracts placed; budget within estimates

– Dipoles and quadrupoles: manufacturing design completed; raw materials ordered; tooling manufacture in progress

– H/V correctors: manufacturing design in progress

Technical (and schedule) risks– Dipoles: lamination stamping sub-contractor not experienced with accelerator magnets

– Quadrupoles: manufacturer unexperienced with laminated yokes

– Steerers: quality issues from manufacturer in the past

Magnetic measurements– Scope defined; standard measurements for quadrupoles and steerers

– Refurbishment / development of tooling required for dipoles

– Important workload of this project will add to the present situation
