Production of probes with carbon nanotubesSpringer Science and Business Media LLC - Tập 53 - Trang 903-905 - 2010
S. V. Antonenko, O. S. Malinovskaya
A method for producing carbon nanotubes by magnetron sputtering of a carbon target is proposed. It allows modification of traditional probes for probe microscopy using carbon nanotubes, thus substantially improving their characteristics. Probes with nanotubes with a tip radius of rounding of several nanometers can be used for precise scanning, quality control of samples, and nanolithography.
A high-voltage high-current switch on the basis of triggered vacuum switchesSpringer Science and Business Media LLC - Tập 59 - Trang 362-367 - 2016
M. R. Akhmetgareev, V. P. Ivanov, L. P. Menakhin, V. A. Sidorov
A KV-25-300 high-voltage switch for dc voltages of up to 25 kV and currents of up to 300 kА for pulse powering of loads at a pulse rise rate of up to 10 kA/μs was developed and tested. The switch consists of two series-connected RVU-43-1 triggered vacuum switches, thus making it possible to reduce the breakdown probability at the maximum operating voltage to a value of <10–7. The total switching-o...... hiện toàn bộ
Detection of Light Pulses Using an Avalanche-Photodiode Array with a Metal-Resistor-Semiconductor StructureSpringer Science and Business Media LLC - Tập 48 - Trang 355-363 - 2005

The results from tests of avalanche-photodiode (APD) arrays with a metal-resistor-semiconductor (MRS) structure are presented. The photodiodes, having a working area of 1 × 1 mm2, operated in the Geiger mode. MRS APD arrays were tested using light-emitting diodes and as components of scintillation counters with dimensions of the plastic of 50 × 50 × 5 mm, in which light was collected with the help...... hiện toàn bộ
A Controlled Magnetic ClampSpringer Science and Business Media LLC - Tập 61 - Trang 751-752 - 2018
V. S. Edelman
A clamp for establishing a thermal contact between cryostat components in a vacuum is described. The contact is established by pressing heat conductors to each other using a permanent magnet and is broken or established by applying a current pulse of the required polarity to the winding around an iron magnetic core. The device is held in the open state by a second permanent magnet. Through the pre...... hiện toàn bộ
An AF-1 Analytical Fourier-Transform Spectrometer for a Wide Field of ApplicationsSpringer Science and Business Media LLC - Tập 46 - Trang 219-221 - 2003
A. A. Balashov, V. A. Vagin, A. V. Viskovatykh, G. N. Zhizhin, V. I. Pustovoit, A. I. Khorokhorin
An AF-1 Fourier spectrometer is developed on the basis of a two-beam interferometer with a pendulum-type scanning unit, which is manufactured of a special alloy ensuring its time stability, and a stationary block of plane reflectors made of a highly stable glass. The performance characteristics of the instrument are as follows: the IR spectrum region is 400–4000 cm–1; the highest resolution is 1 c...... hiện toàn bộ
Facility for investigating the propagation of sound in the surface layer of the earth’s atmosphereSpringer Science and Business Media LLC - Tập 48 - Trang 256-258 - 2005
N. P. Krasnenko, A. N. Kudryavtsev, E. E. Mananko
The facility is intended for investigating the propagation of sound waves in the surface layer of the Earth’s atmosphere. It permits the directional radiation, and recording, of high-level audio-frequency sound. The maximum sound level (referred to a distance of 1 m) is as high as 151 dB; the antenna beamwidth is 6° to 16°, depending on the frequency; the side-lobe level does not exceed −20 dB; an...... hiện toàn bộ
A temperature stabilization system for diode lasersSpringer Science and Business Media LLC - Tập 43 - Trang 580-581 - 2000
V. A. Vasil'ev, V. A. Zhmud'
A system is described that measures the temperature of diode lasers and stabilizes it with an accuracy within ±0.005°C and ±0.02°C, respectively. The design is simple in tuning and convenient in use. Recommendations for the empirical tuning of the system controller are given.
