Definitions

  • a further object is to insure that the pitch of the helix will be accurately maintained throughout its useful life.
  • the loss region originally extended for example, for about three inches over the center portion of the rods
  • the same attenuation of the reverse waves may now be obtained with a loss region of only one inch.
  • the loss-free interaction region has thus been increased by two inches resulting in a higher gain per given total length of helix.
