Title: Multipole Magnet Design Selection and Permanent Magnet Material Selection


1
Multipole Magnet Design Selection and Permanent
Magnet Material Selection
  • May 18, 2000
  • Stanford University
  • Manufacturing Modeling Lab
  • Shun Takai

2
Agenda
  • 1. Motivation
  • 2. Cost-Specification Analysis
  • Flow Down of the Product Targets
  • Evaluation of the candidates
  • Selection of the best candidate
  • 3. Conclusion

3
Motivation
  • Needs for multiple requirements satisfaction
  • NLC
  • Feature (physicists requirements)
  • Cost (Governments requirements)
  • Cost-Specification Analysis highlights design
    and/or material candidate that satisfies both
    target specification and target cost

Multipole Magnets
  • Quantity 1500 quadrupole magnets in Main Linac
    system
  • 6000 permanent magnet sets

Agenda
  • 1. Motivation
  • 2. Cost-Specification Analysis
  • Flow Down of the Product Targets
  • Evaluation of the candidates
  • Selection of the best candidate
  • 3. Conclusion

6
Targets Flow Down
  • Flow down of the product targets to the focus
    structures

7
Focus of the Analysis - Structure
  • Focus (1) Main Linac multipole magnet system
  • (2) permanent magnet used in
    quads

8
Specification Flow Down - VOC and Specs
9
Cost Flow Down
  • Target cost of a structure
  • Calculated relative to the worth of the NLC

Worth of a structure Worth of NLC
Target cost of a structure

Target cost of NLC
How can I calculate the worth of a structure?
10
Worth Allocation Main Systems
  • Worth of NLC is equal to the total worth of VOC

1. Calculate worth of NLC specification from
worth of VOC (Translate VOC to NLC
specs) 2. Calculate worth of main systems from
its contribution to achieve NLC specs
(Larger the contribution, larger the worth)
11
Worth Allocation Main Systems
  • 1. Calculate worth of NLC specification from
    worth of VOC
  • (Translate VOC to NLC specs)

12
Worth Allocation Main Systems
  • 2. Calculate worth of main systems from its
    contribution to achieve NLC specs
  • (Larger the contribution, larger the worth)

13
Worth Allocation Main Linac Sub-systems
  • Calculate worth of Main Linac sub-systems

14
Worth Allocation Main Linac Sub-systems
  • 1. Calculate worth of Main Linac specs from
    worth of NLC specs
  • (Translate NLC specs to Main Linac specs)

15
Worth Allocation Main Linac Sub-systems
  • 2. Calculate worth of Main Linac sub-systems
    from its contribution to achieve Main Linac specs
  • (Larger the contribution, larger the worth)

  • 3. Conclusion

20
Cost Evaluation
  • Select structure candidates with
  • Actual Cost lt Target cost
  • or
  • lt 1

Relative Cost
21
Performance Evaluation
  • Overall performance of each candidate is measured
    by weighted average of individual spec
    satisfaction
  • Weighting is relative importance of each spec to
    the customer

22
Performance Evaluation - Weighting Calculation
  • Weighting of each spec is calculated by relative
    weight of each spec

23
Performance Evaluation
  • Select structure candidates with
  • Relative performance gt 1

24
Design Selection of Multipole Magnet System
  • Design candidates Electro-magnet vs hybrid
    magnet
  • (Strontium Ferrite)

25
Material Selection of Permanent Magnet
  • Material candidates Strontium Ferrite, Sm2Co17,
    Nd-Fe-B

26
Trade-Off Analysis
  • Design can be optimized by trade-off analysis of
    each candidate

27
Agenda
  • 1. Motivation
  • 2. Cost-Specification Analysis
  • Flow Down of the Product Targets
  • Evaluation of the candidates
  • Selection of the best candidate
  • 3. Conclusion

28
Conclusion
  • Cost-Specification Analysis enables an engineer
    to select the best candidate that satisfies both
    specification and cost targets
  • By applying Cost-Specification Analysis to all
    components and by selecting the best candidate,
    the final product can satisfy both required
    feature and cost simultaneously
  • Looking for second application in order to
    validate this approach

Next Linear Collider (NLC)
  • NLC is a 20-mile long linear collider that
    smashes electrons and positrons in order to
    create new particles
  • The goal is to produce 10 times higher energies
    than the present linear collider (SLC)
  • NLC is consists of three main systems
  • Injection (Beam injection)
  • Main Linac (Acceleration)
  • Beam Delivery (Collision and detection)

34
Quadrupole Magnets (Quads)
  • Quadrupole magnets are used in order to focus
    electron and positron beams using magnetic field
  • Without focusing beams, we can not collide beams
    accurately

35
Customer Needs Identification (Customer Value
Chain Analysis Priority Matrix)
  • US Gov. is the critical external customer and
    SLAC physicists are the critical internal
    customers
  • The priorities of SLAC and the Gov. are different
  • SLAC needs to satisfy both feature and cost

Future Study
  • Include lead time to Cost-Specification Analysis
  • Consider availability of each material
  • Trade-off analysis
  • High cost, high performance
  • vs
  • Low cost, low performance
