Results of studying multichannel gas electron multipliers with 1-mm-thick metal electrodes, perforated over the entire working area by 1-mm-diameter holes with a 1.5-mm distance between them, and a 3-mm gap between the electrodes are described. The i

A shape of the signals in proportional chamber with preamplification gap and electron component extraction from proportional discharge has been investigated. It was shown for Penning mixtures that in proportional discharge besides the primary avalanc

Studied in this work is the cooling of a beam of sodium atoms upon its reflection from an evanescent light wave. The cooling mechanism is associated with the spontaneous transitions of the atoms between the hyperfine-structure sublevels of the ground

A novel experiment for direct searches of the Dark Matter with liquid argon double-phase chamber with a mass of liquid Ar up to several hundred tons is proposed. To suppress the b-, g- and n0- backgrounds, the comparison of scintillation and ionizati

Theoretical and experimental studies on the properties of the radiation force acting on two-level atoms in a bichromatic standing light wave are reported. It is shown that on an atom at rest a rectified gradient force is exerted having a great magnit

We report an endlessly single mode, fiber-optic confocal microscope, based on a large mode area photonic crystal fiber. The microscope confines a very broad spectral range of excitation and emission wavelengths to a single spatial mode in the fiber.

We report the theoretical prediction and the observation of a stimulated novel magneto-optical radiation force, acting on atoms located in a static magnetic field and irradiated by the resonant field of two counterpropagating monochromatic laser beam

One-dimensional localization of sodium atoms in a standing spherical light wave has been observed. The atoms have an oscillatory motion with an amplitude of approximately lambda/10 along the nodes (or loops) of the wave.

The authors report experimental results demonstrating that the friction force acting on atoms in a bichromatic standing light wave can substantially differ from that in a monochromatic standing wave. Even a sign reversal can occur in a laser frequenc
