NED I EU Integrated Activity FP6

• RAL programme, total 424 kEu, RAL 364kEu, FP6 60
  kEu
• RAL WP involvement
• Responsible for coordinating the IDI Work package
• Conventional Insulation Development at RAL
• Innovative Insulation at CEA
• Magnet design
• Magnetic
• Mechanical

NED I Insulation Development

• Development of the Insulation Specification
  EDMS548037
• Conventional Insulation Development
• Basic materials evaluation
• Glass sizing studies led to the development of
  a commercial tape with polyimide size with JPS
  Glass.
• The tape material is robust for cable taping and
  coil winding
• Laminates show good electrical and mechanical
  properties after heat treatment and impregnation
• Development of test samples and characterisation
  techniques
• Short Beam Shear and Work of fracture
• See final IDI report by Simon Canfer EDMS 815074

NED I Magnet Design

• Magnetic Design
• Optimisation of the Cosine theta geometry as part
  of the MDO Group
• Use of Optimisation routines developed by Vector
  Fields
• Evaluation of the Helical winding configuration
  for a NED type magnet - Paper to MT20
• Mechanical Design
• Mechanical modelling of 15T 88mm Cosine theta
  dipole
• Development of ANSYS model covering
• Collaring, yoking, cooldown and powering
• Objective to keep the compressive stress at the
  mid plane lt150MPa

• Duration 36months Jan 07 Dec 09
• RAL WP responsibilities/commitments
• Generic RD for high field magnets
• Ongoing Conventional Insulation development
• Mechanical design of 15T magnet
• Short Model Coils (SMC) Racetrack coils

NED I.5 current programme

• Generic RD - Ongoing Conventional Insulation
  development and application
• NED I - about basic insulation materials
  development and characterisation
• Main emphasis on laminates properties of the
  insulation
• NED I.5 Behaviour of the insulation in a coil
  matrix with the cable
• Emphasis now on cable stacks to see the
  interactive effects
• Real application of the insulation system in the
  racetrack SMC coils
• Still want to pursue the opportunities for basic
  RD
• Improvement of the matrix properties which may
  ultimately be important for magnet performance
• Radiation hardness cyanate esters
• Matrix toughness nano-clays, dendritic
  inclusions
• Silanes to improve bonding to the cable
• Study of Radiation effects

NED I.5 current programme

• Time to Review this programme
• Relate to Cern HFM programme and EU FP7 IA HFM
• Main focus to date has been on the SMC programme
• Now starting to manufacture parts and coils
• Expect this to run to Autumn 2008
• Now propose to concentrate again on insulation
  development
• Mechanical properties of the coil matrix through
  stack studies
• Improvement of the epoxy matrix properties
• Radiation hardness studies
• Mechanical Modelling assessing the future
  direction of this work
• Complete studies on the 88mm 15T
• Look at 110mm 13T designs cosine theta and
  alternatives

8
Programmes - future

• IA HIGH FIELD MAGNET (HFM) RD - NEDII
• RAL ASD proposed WP involvement
• WP2 Support studies - Insulation radiation hard
  materials and epoxies
• WP36 Magnet design magnetic and mechanical
• WP5 Corrector magnet Nb3Sn design and
  manufacture

9
Programmes - future

• IA HFM RD NEDII proposed RAL input areas
• WP2 Support Studies
• Insulation and Radiation Hardness studies
• Tasks conventional and innovative insulation
  improved impregnation in terms of radiation and
  strength
• Specification mechanical electrical
  radiation
• Characterisation techniques for the coil matrix
  
• Test programme definition and certification of an
  insulation system
• Test programme execution and management
• Links of this programme to mechanical studies
  through measurement and characterisation of
  winding packs modulus thermal contraction etc
• Develop synergy of rad hard materials work to
  other programmes such as targets unique links
  between materials and the engineering design in
  RAL ASD
• Infrastructure for rad hard studies sources
  handling testing facilities

10
Programmes - future

• IA HFM RD NEDII proposed RAL input areas
• WP3 and WP6 Dipole or Quadrupole models and
  prototype
• Magnet apertures will be large gt100mm and fields
  high 13T
• Alternative magnet designs to be studied and
  evaluated
• Main input should be as mechanical modelling for
  the design phases building on the work from NEDI
  and the SIP(NEDI.5) programme
• This mechanical modelling should be closely
  linked to the materials programme
• Also the development of test assemblies to
  confirm materials behaviour and model predictions
  sub-modelling

11
Programmes - future

• IA HFM RD NEDII proposed RAL input areas
• WP5 Nb3Sn correctors
• The experience gained in the CNI FP7 programme
  for qpole correctors would put RAL a strong
  position to lead the Nb3Sn corrector package when
  combined with the experience gained in the
  manufacture of Nb3Sn racetracks under the SMC
  programme
• The magnets are at the scale where we could take
  on the design and manufacture and testing of
  prototype coils

12
Programmes - future

• IA HFM RD NEDII proposed RAL input areas
• Summary
• Proposed Programme
• Staff 9sy
• Recurrent 400kEu
• Duration 4 years
• Note this is the proposal made to RAL management
  and to Cern
