AbstractAbstract
[en] A number of theories of the formation of the planets advocate that the terrestrial planets were originally of cosmic composition and that it is only subsequent evolution that has removed their volatile components. This paper shows that such protoplanets could have remained in the terrestrial planet region without significant changes occurring in their orbits for an acceptable time interval. (Auth.)

AbstractAbstract
[en] The author has recently constructed an extensive analytic system of averaged differential equations containing the secular evolution of the orbits of the eight main planets, accurate to second order in the planetary masses and to fifth order in eccentricity and inclination, and including corrections from general relativity and the Moon. Here the author describes the results of a numerical integration of this system, extending backwards over 200 million years. The solution is chaotic, with a maximum Lyapunov exponent that reaches the surprisingly large value of ∼ 1/5 Myr-1. The motion of the Solar System is thus shown to be chaotic, not quasiperiodic. In particular, predictability of the orbits of the inner planets, including the Earth, is lost within a few tens of millions of years. (author)

AbstractAbstract
[en] The purpose of the chopper/buncher system for the RTM injector is to chop a 100 keV 5 mA dc electron beam into 600-long pulses at 2380 MHz and then bunch these beam pulses to 100 at insertion into the 5 MeV injector linac. These beam manipulations must contribute a minimum increase in the phase space of the beam such that, at the entrance to the injector linac, the transverse emittance is less than 5π mm-mrad. Phase-shift measurements on the chopped beam indicate that the bunching fields are sufficient to achieve the required longitudinal compression. Beam envelope measurements, using wire scanners on the chopped and bunched beam, show that the emittance remains within design goals

AbstractAbstract
[en] A quantitative study of periodic orbits and particle trapping near them in the gravitational field of a uniformly rotating homogeneous solid parallelepiped is made. It is found that particle trapping leads to the possibility of formation of ring-like structures around the parallelepiped and blob-like concentrations around the equilibrium points of the parallelepiped.

AbstractAbstract
[en] This paper reports on the EIFEL experiment, designed to investigate the stability of a dense array of tubes in crossflow, at a high, supercritical Reynolds number The phenomenon proved not to be of pure fluidelastic type. The effect of high Reynolds (in fact of a lower viscosity), if any, is small

AbstractAbstract
[en] The discovery of the Principle of Phase Stability by Vladimir Veksler and Edwin McMillian and the end of the war released a surge of accelerator activity at the Lawrence Berkeley Laboratory (then The University of California Radiation Laboratory). Six accelerators incorporating the Principle of Phase Stability were built in the period 1945--1954
