Update of ps needs

Update of PS Needs

  • V109 has one more 6-3-120 (now 4 instead of 3) and runs at a higher current (1050 amps)

    • Requires another 500 KW supply to get the needed volts.

    • Have space for 1 more 500 KW in TSB.

    • Only remaining 500 KW PS are old Transrex’s, we are checking on getting an additional one (or other options, and checking the ramp).

  • V110 has one less EPB (now 5 instead of 6) and runs at a higher current (1400 amps)

    • Does not require an PS changes, will need to re-calculate the ramp.

  • Q109 is now two different quads (3Q120, 3Q60) which can run on one supply.

  • Two possible 3Q120’s (quads) in the carrier tunnel (unlined region)

    • Will need an additional PS each (there is room for them and we have spares)

  • Cable lengths and costs all need to be re-estimated.


Update of regulation needs

Update of Regulation Needs

  • Magnet Strings regulation requirements are looser with the new beam optics.

    • Could use less regulation than we have budgeted for, if this remains true.

    • Not clear if loosening the regulation is worth the money saved.

    • Don’t need to decide until FY2003.

    • Costed filters for all 7 strings, and BmLB systems for 3 strings, HOLEC transductors and special FNAL electronics for all 7 strings.


Summary

Summary

All these comments are very preliminary and Steve Hays will check in detail to see what are the final implications.

  • Main Changes:

    • Need extra 500 KW for V109.

    • Need 2 more quad PS if put quads in carrier tunnel.

    • PS regulation requirements are looser.

    • Cable lengths and numbers.

    • (need to re-do ramp calculations and cable calculations/costs)

  • Implications:

    • Can we get additional cable (500 kcm) or is it too late? Not sure if we will need it or not…

    • Additional costs are for 500 KW PS and quads and cables. Estimate several ten’s of thousands of dollars (FY$98).

    • Might be able to save money on PS regulation, but we would need to think long and hard before doing that.
