[en] The paper presents transmission spectra of multicomponent solid solutions based on CeF₃, CdF₂, and PbF₂ crystals as well as Bi₄Ge₃O₁₂, NaBi(WO₄)₂, and Bi₁₂SiO₂₀ before and after irradiation with ⁶⁰Co and ¹³⁷Cs γ-radiation. The scintillation decay curves of the investigated crystals are given. It is shown that the radiation resistance of the single crystals of CdF₂ doped with CeF₂ and LaF₃(∼1--3 mol.%) is over 10⁹ rad

[en] The accelerating resonator of the main part of linear accelerator of the Moscow Meson Factor is described. The resonator is an oscillatory system consisting of four sections connected by three resonant bridge couplers. A brief description is provided of the procedure for tuning of the radiotechnical parameters of the sections and resonators. The results of tuning of the accelerating system of the main accelerator part performed during 1980-1989 are provided. 17 refs., 3 figs

[en] The construction of a position-sensitive microchannel-plate detector is described. The detector design makes use of the technique of dividing charge by isolated collector elements. A photocathode, which increases the efficiency of detecting X-rays, is applied to the microchannel plate assembly front side. The minimum event-processing time is no more than 45 μsec. The detector has been tested with model signals. As a part of a RSL-1500 spectrometer, the detector has been used for the registration of ultrasoft characteristic X-radiation (MξMo, L_2,3Al) with a radiation grazing angle of 5 degree-8 degree. The resolution obtained when using the detector corresponds to that of a spectrometer with 25-μm wide slits. 5 refs., 3 figs

[en] A unit is described for obtaining a flow of partially ionized metal vapor. Evaporation is accomplished by inductive heating of the crucible. Vapor is ionized in high-frequency discharge sustained by an inductor. The voltage across the inductor was 300-500 V at a frequency of 440 kHz and the ion current in the substrate amounted to 500 mA for density 10 mA/cm². 2 refs., 2 figs

[en] A source of gas ions is described which forms an ion beam of 200 mm in diameter with a current-density-distribution nonuniformity of ≤ ±10% over the cross-section and a current of up to 30 mA at an accelerating voltage of up to 50 kV. Nitrogen, argon, and air were used as working gases. Ion-emitting plasma was generated by a volume reflecting discharge that was initiated and supported by electrons injected from auxiliary reflecting cold-cathode discharge. Ion acceleration and formation of the beam were performed with a three-electrode multiaperture ion-optical system

[en] The review describes the properties of detector materials used in the electron-photon calorimetry: scintillators, Cherenkov radiators and appropriate light detectors, and dielectrics for ionization chambers. The physical parameters (density, radiation length, Molier radius, etc.) of the active media of the calorimeters are presented. Scintillator characteristics (emission spectrum, light yield, luminescence decay time, etc.) are discussed, as well as temperature and radiation effects

[en] The console transmits as many as twenty different instructions through an RS-232 serial interface. To synchronize the exposure time with the system operation a photographic camera is used

[en] Measurement techniques, data processing, and the scintillation output of liquid xenon versus the energy of soft X-rays and γ-quanta are described. The behavior of liquid xenon and other scintillators is anomalous, i.e., the light yield drops with rising linear density of ionization on the track

[en] The operating principle and main characteristics of a beam-intensity modulation system (BIMS) for pulse-packet irradiation of a fast-circulation bubble chamber by a proton beam slowly extracted from an accelerator are described. The BIMS stabilizes the exposure dose of each pulse according to the signal from a monitor on the physics apparatus by pulse-duration modulation of the irradiation time. The repetition frequency of the pulses in a packet is 1-50 per second. The duration of any pulse in a packet can be varied from 0 to 80 μsec. The BIMS is located in a particle channel, which makes it unnecessary to add equipment to the accelerator complex or affect its operation. 3 refs., 3 figs., 1 tab

[en] The state and trends in development of parallel methods for detection of event multiplicity and coordinates employed in high-energy physics are examined. It is noted that both analog and digital logic devices and processor elements have been traditionally used to increase the speed and flexibility of devices created for physics-event sampling electronic system designed for nuclear physics. A number of examples are provided that illustrate the wide possibilities of analog-to-digital converters with parallel input-voltage conversion and a maximum clock frequency of ≥100 MHz. Methods for construction of parallel counters are described, and the outlook is examined for their use in the creation of efficient devices for event sampling by signal multiplicity, special-purpose processors, and parallel data compressors. Also examined are methods for the design of parallel coders and majorant coincidence systems employing syndrome coding and a method of ones compression based on regular matrix structures. 49 refs., 21 figs., 2 tabs
