摘要： A traveling wave tube and method of operation is disclosed. The traveling wave tube includes a slow wave structure such as a helix member provided with input and output ends and located within a tube member. An electron gun assembly is adjacent the input end for injecting electrons as an electron beam along an axial path through the helix member. A magnetic focusing device generates a magnetic field having a given strength to confine the beam to the axial path. The given strength of the magnetic field is sufficient to confine the beam only when the power level of the microwave input signal is selected such that the given power level of the microwave output signal is at least 6 dB lower than the power level of the microwave output signal at saturation. Boron Nitride (BN) supporting rods are engaged between the tube and helix members for supporting and transferring heat away from the helix member.

摘要： A low-loss magnetic structure that provides an electron beam focusing field that can be accessed without field reversal. More specifically, the structure provides a uniform magnetic field that can be accessed from an adjacent field-free chamber within which an electron beam source of any size can be housed. The field-free chamber is separated from uniform field by a passive ferromagnet having a hole through which the electron beam can pass. The passive ferromagnet is instrumental in preventing the uniform field from entering the field-free chamber.

摘要： A betatron, adapted, e.g., for use as a high-energy electromagnetic radiation source in a borehole well logging tool, includes modulator circuitry for actively controlling the electron beam radius during acceleration and for extracting the electron beam at or near maximum magnetic field strength. Such control may be effected by suitable separate pulsing of field-coil and core-coil magnets, and results in enhanced efficiency of betatron magnet-excitation power conversion and beam end-point energy stability and intensity over a range of operating temperatures.

摘要： In a magnet arrangement suitable for providing PPM focusing, cylindrical magnets 4 have inclined inner faces 6 and 7 meeting at an edge 8. Pole pieces 9 are contiguous with the inclined faces 6 and 7 to provide a relatively large field within the volume enclosed by the arrangement. Preferably, the magnet is of a type II magnetic material.

摘要： A traveling wave tube (10) and method of operation is disclosed. The traveling wave tube (10) includes a slow wave structure (SWS) (14) such as a helix member (26) provided with input and output ends (28, 30) and located within a tube member (38). An electron gun assembly (12) is adjacent the input end (28) for injecting electrons as an electron beam (18) along an axial path through the helix member (26). A magnetic focusing device (50) generates a magnetic field having a given strength to confine the beam (18). The given strength of the magnetic field is sufficient to confine the beam (18) only when the power level of the microwave input signal is selected such that the given power level of the microwave output signal is at least 6 dB lower than the power level of the microwave output signal at saturation. Supporting rods (44) oriented in the "C" direction are engaged between the helix and tube members (26, 38) for supporting and transferring heat away from the helix member (26).
