Supplement of the proposal

Reply to the TB questions :

1. Is it essential to the ILC to run a superconducting quadrupole at the ATF2?
2. Do we need more "complete" prototype than the ATF2 one with simpler structure, i.e. no outgoing beam, large bore, short length, no detector solenoid etc. ?
3. Are there the risks for the installation at the ATF2 beam line ?
4. What are the resources and the schedule ?

Updates :

1. Author list
2. Optimized configuration of a SC-Q system
   - the warm QD0/SD0 and the cold QF1/SF1 for smaller multipole components
   - need justification by optics simulation
3. Ultra low optics
   - Can we realize the pushed beta optics at present beam line ?
4. magnet and Cryogenics system
   - BNL responsibility - changes in the design, i.e. coils/current, heat loads
   - KEK responsibility - interface box and re-condensation cryo-coolers with "vibration free"
5. Support system
   - LAPP table
   - movers are necessary ?
   - alignment; KEK in collaboration with BNL.
6. Laser interferometer : vibration monitor of coils inside the cryostat
   - BNL design in collaboration with Monalisa group, Oxford university.
7. Schedule and timeline
   - construction and installation
   - test at BNL and beam test at ATF2
   - a series of beam tests, e.g. nominal optics, Ultra-low beta optics, etc.
