    Frequency multiplied harmonic gyrotron-traveling-wave-tube amplifier (1994)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 1 (1994), S. 2058-2062

    Topics: Physics
    Notes: Numerical simulations of a W-band two-stage tapered, frequency multiplied gyrotron- traveling-wave-tube amplifier are reported. Unlike conventional harmonic gyrodevices, a drive signal at the fundamental harmonic frequency is injected in the first stage for beam modulation, and amplified output radiation is extracted from the third harmonic cyclotron resonance interaction. Numerical results show that broadband millimeter wave radiation is obtained with an efficiency of 10%–15%, a gain of ∼30 dB, and an instantaneous bandwidth of ∼10% at a center frequency of 95 GHz for Δvz/vz=2%.

    Folded waveguide gyrotron traveling-wave-tube amplifier (1995)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: A compact, low cost gyrotron traveling-wave-tube (gyro-TWT) amplifier capable of producing high-power, broadband, millimeter wave radiation is reported. The interaction circuit is a periodic, magnetic field plane (H plane) bend, transverse folded waveguide employed with a high-power axis-encircling electron beam. Transverse beam modulation and wave amplification in the folded waveguide gyro-TWT are observed in both linear theory and large signal simulations. Calculations from an equivalent circuit model and a three-dimensional electromagnetic code predict a mode coalescing of the first stop-band in a periodic structure. The mode coalescing is verified from experimental measurements. © 1995 American Institute of Physics.

    A theory of cavity excitation by modulated electron beam in connection with application to a klystron amplifier (1993)
    New York, NY : American Institute of Physics (AIP)
    Physics of Fluids 5 (1993), S. 1349-1357 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Based on an equivalent circuit representation of a cavity impedance, a theoretical model of the cavity excitation by a modulated electron beam is developed. The beam current modulation is initiated by the first cavity and amplified in drift section between the first and second cavities. Properties of the second cavity excitation by the beam are described in terms of the phase shift Ψ and amplitude φ2 of induced voltage in the cavity. The phase shift Ψ and amplitude φ2 are determined in terms of the frequency difference (η), the cavity Q value, the voltage multiplication factor (χ), and magnitude (φ1) of the first cavity voltage. The voltage multiplication factor is proportional to the beam intensity, Q value, and distance between the first and second cavities. On the other hand, it is inversely proportional to frequency and capacitance of the cavity, and beam electron velocity. Because the induced voltage in the second cavity is in phase with the first cavity voltage at upshifted cavity frequency, amplitude of the current modulation at the upshifted frequency is larger than that at the downshifted cavity frequency. Experimental study is carried out by making use of a klystron amplifier operable from 4.4 to 5 GHz. Experimental data from the klystron agree remarkably well with amplifier performance profiles predicted by the theory.

    Linear analysis of backward wave oscillations in azimuthally varying transverse electric (TE) modes (1993)
    New York, NY : American Institute of Physics (AIP)
    Physics of Fluids 5 (1993), S. 1639-1646 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: A linear analysis for a gyrotron backward wave oscillator operating at a general transverse electric (TEln) mode of a cylindrical waveguide (slotted or uniform cross section) has been developed using a Maxwell–Vlasov equation under the tenuous beam approximation. The equation is solved by Laplace transformation to allow easy insertion of the boundary values. The start-oscillations conditions are determined from an interference of the waveguide and beam modes with appropriate amplitudes and phases. The theory is used to determine the design parameters for stable operation of a second cyclotron harmonic gyropeniotron amplifier at 35 GHz in the π mode of a six vane magnetron-type circuit with a 70 kV, 3 A beam.

    Paediatric post orchidopexy analgesia—effect of diclofenac combined with ilioinguinal/iliohypogastric nerve block (1994)

    Notes: SummaryWhen ilioinguinal/iliohypogastric nerve blockade is used to provide postoperative analgesia after paediatric orchidopexy, supplemental analgesia may be required postoperatively. Diclofenac is a nonsteroidal analgesic which produces effective analgesia after tonsillectomy. We examined the effect of combining diclofenac with inguinal field block for post orchidopexy analgesia. Following induction of anaesthesia, group 1 (n= 25) received ilioinguinal block and rectal diclofenac (2 mg·kg−1) and group 2 (n= 25) received ilioinguinal block alone. Objective pain scores were assessed for the first three h postoperatively and the incidence of postoperative rescue analgesia, noted. Pain scores were significantly less in group 1 at 45, 60, 90 and 120 min postop (P 〈 0.05). The postoperative analgesic requirement was significantly lower in the diclofenac group compared to control (P 〈 0.05). A single administration of rectal diclofenac is a simple and effective method of significantly improving analgesia associated with inguinal field block, after paediatric orchidopexy.
