    Ultrastructural observation on a colloid cyst of the third ventricle (1984)
    Springer
    Acta neuropathologica 65 (1984), S. 41-45

    Notes: Summary The case involves a colloid cyst of the third ventricle in a 20-year-old man. The lining epithelia of the cyst were composed of two different types of epithelial cells; stratified squamous cells and mucincontaining columnar cells. The presence of both squamous and glandular cells in the cyst wall supports the contention that the colloid cyst in the present case derived from an non-neuroepithelial source. The clinico-pathology of this cystic tumor is compared here with other epithelial cysts of the central nervous system (CNS), especially Rathke's cyst.

    Enhancement of amplification characteristics in a plasma-filled Cherenkov laser at millimeter wavelengths (2000)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 87 (2000), S. 1626-1631

    Notes: On the basis of the fluid model of the electron beam, amplification characteristics of a two-dimensional plasma-filled Cherenkov laser at 100 GHz bands are analyzed. By injecting a dense plasma into the background of a Cherenkov laser, the coupling between a relativistic electron beam and an electromagnetic wave at millimeter wavelengths has been improved, and the weak beam–wave interaction problem has become less serious. In particular, we show that due to electron–ion collisions in the background plasma, proper choices of parameters are essential for good operation in this regime. The numerical results indicate that a Cherenkov laser with background plasma can generate higher output power with a greatly enhanced growth rate at a more reasonable interaction length. The plasma injection, in addition, enables the device to gain more output power with a higher beam current. © 2000 American Institute of Physics.

    Efficiency enhancement in a Cherenkov laser by a proper permittivity variation (1997)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 82 (1997), S. 5907-5912 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: With the aid of particle simulation, we discuss efficiency enhancement in a single-pass Cherenkov laser by varying the permittivity of a dielectric sheet loaded on a parallel plate waveguide. For the analysis of the problem, a two-dimensional model for the Cherenkov laser is considered which is composed of a planar relativistic electron beam and a parallel plate waveguide, one plate of which is loaded with a dielectric sheet. In order to maintain the synchronism between an electron beam and an electromagnetic wave, the permittivity of the dielectric is properly varied in accordance with the variation in the average velocity of the electron beam. The result of numerical simulation shows that the efficiency of energy transfer from the electron beam to the electromagnetic wave is greatly enhanced by properly varying the permittivity of the dielectric sheet. © 1997 American Institute of Physics.

    Efficiency enhancement in a Smith–Purcell free-electron laser (1995)
    Woodbury, NY : American Institute of Physics (AIP)

    Topics: Physics
    Notes: A systematic method to enhance the efficiency of energy transfer in a Smith–Purcell free-electron laser composed of a metallic grating and a relativistic electron beam is proposed. To maintain the synchronism between an electron beam and a slow electromagnetic wave propagated along a metallic grating, either one of the three grating parameters is adiabatically changed in the direction of wave propagation in accordance with the decrease in the drift velocity of the electron beam. The numerical simulation, which takes into account the reflection or scattering due to discontinuities in the grating parameters, demonstrates sufficient efficiency enhancement in energy transfer. © 1995 American Institute of Physics.

    Nonlinear space-charge waves in a relativistic electron beam drifting along a Kerr-like medium (1996)
    Woodbury, NY : American Institute of Physics (AIP)

    Topics: Physics
    Notes: We investigate the nonlinear characteristics of space-charge waves, which propagate along a relativistic electron beam drifting near the surface of a semi-infinite Kerr-like medium, under the condition that the drift velocity of the electron beam does not exceed the Cherenkov threshold. On the basis of the linear fluid model for the electron beam and the stationary wave analysis, we obtain some interesting features for the nonlinear space-charge waves such as power dependence of wave numbers and hysteresis characteristics. © 1996 American Institute of Physics.

    Notes: A method for enhancing the efficiency of energy transfer from a relativistic electron beam to an electromagnetic wave in a Cherenkov laser is proposed. In a two-dimensional Cherenkov laser composed of a planar relativistic electron beam and a parallel plate waveguide loaded with a dielectric grating, either one of the grating parameters, or the slot width and the groove depth, is tapered or gradually decreased in accordance with the decrease in the drift velocity of the electron beam. The numerical simulation demonstrates that sufficient efficiency enhancement can be achieved by a tapered dielectric grating. © 1996 American Institute of Physics.
