Motion of a deformable drop of magnetic fluid on a solid surface in a rotating magnetic field

The behavior of a magnetic fluid drop lying on a solid horizontal surface and surrounded by a nonmagnetic liquid under the action of a uniform magnetic field which is rotating in a vertical plane with low frequency (of the order of 1 Hz) has been investigated experimentally. Shape deformation and translatory motion of the drop were observed and studied. The drop translation velocity for different field amplitudes and field frequencies has been measured.Comment: 9 pages, 4 figure

Dynamics of magnetic fluid drop's shape in rotating and stationary magnetic fields

Abstract A drop of magnetic fluid was experimentally studied in a rotating magnetic field H r with the additional influence of a stationary magnetic field H s : The conditions of a drop break were studied with different values and directions of intensities between rotating and static magnetic fields. The results of the experiment were theoretically well grounded.

Modulator For Klystron 5045

The first modulator for a forinjector klystron of VEPP -- 5 is being tested now in BINP in Novosibirsk. The forinjector of VEPP -- 5 will involve a 510 MeV Linac consisting of four accelerating modules. The Klystron 5045 manufactured at SLAC [1] was chosen to drive the accelerating modules. This paper presents a design and some testing results of this modulator. I. INTRODUCTION The modulator is a conventional line type modulator with some supplementary characteristics. A simplified electrical layout of this modulator is shown in Fig. 3. The voltage value in a filter capacitor CF is determined by a phase-control system with six SCRs. The CF charging current is limited by three 500#H inductors connected to the primary winding of the rectifier transformer. In addition, this system provides "soft-start" capability and fast protection. The PFN is resonantly charged through a charging high-voltage SCR-switch (HV-switch), a charging inductor, and de-spiking circuits. The resonant PFN charge..
