JVB/KHL 2018/07/18 agenda

  • We will only have time for a subset of the below.
  • KHL has hearing and visual problems, F2F required.
  • KHL also developing memory problems, will make lots of notes
  • can sign NDA, but prefer to avoid


KHL intro:

  • MSEE UCB 1974 (Josephson Logic) 1977 TMAG paper

  • Integrated circuits: Tektronix, consulting, two startups
  • IEEE 1149.4 analog boundary scan standard

  • ICUBE routed early internet (failed after $e7 → -$e7 )

  • ICID ( $e6 but "shoulda" made RFID a $e10 business )
  • ~20 papers; 1 with Rob Daasch that founded new field (300? citations)

  • ~12 patents incl. foreign (dislike, but protects customers from copycat trolls)
  • Open source software: BSD Y2K patch, Dirvish backup software

  • Married, no kids, helped wife earn MD instead


JVB intro:

  • CV and recent papers on Halbach wheels (resembles launchloop velocity transformer)
  • Spacegrant for EM launch?
  • What do you wish you had time to work on?

  • Other


Launchloop:

  • active "hobby" 1980 to 1988, completing work now
  • 1985 AIAA conference paper, pubs, presentations to space advocacy groups

  • Independent re-invention by many others since ( ie John Knapman PhD in UK)

  • Two research groups currently active, one with >$1M funding + 4 professionals

  • PowerLoop, first practical application: MWhr power storage (can scale beyond TWhr)


Questions:

  • Practical/empirical motor design books (theory/math AND detailed measurement)

    • predictive/adaptive electronic control instead: global stability, loop gain, computation, and redundancy
  • Velocity Transformer: High inertia <- Halbach DC Motor <- Induction generator

    • Stability: can inertia synchronize generator?

  • 3D Motor FEM modelling?

Bolt/Rotor design

  • deflection at ends
  • ≈ 4 kg/m, 3 cm cross section
  • 200 kN induction motor --- how long, how stable?
  • velocity transformer track: air core flat windings, diamagnetic spacing stabilization? Hands waving madly

JVB PSU research

  • what help do you need?
  • would older Tektronix test equipment help you or students?
