Документ Measuring the amplitude-time characteristics of a pulsed high-intensity gamma radiation acceleratorVarian Clinac 600C aCdTe detector(STC "Institute for Single Crystals", 2019) Grigoryev, A. N.; Bilyk, Z. V.; Litvinov, Yu. V.; Cherniavskiy, I. Yu.; Polyansky, N. E.; Snarenky, V. P.; Samofalov, I. A.; Voronkin, E. F.; Sosnutska, O. O.; Petrukhin, S. Yu.; Suchkov, G. M.; Bilyk, N. G.; Indykov, S. N.; Matykin, V. B.; Pysariev, S. A.; Matykin, O. V.; Menshov, S. N.Measurements of the amplitude-time characteristics of a high-intensity pulsed gamma radiation accelerator Varian Clinac 600C with photon energy from 1 to 6 MeV on the equipment using a CdTe detector in both current and pulse modes have been carried out. It is shown that the operation of the CdTe detector in the current mode allows one to control the frequency of the accelerator pulses, and the operation of the CdTe detector in the pulse mode allows for determining the dose in each pulse with an error of 0.06 %. Monitoring the operation of the accelerator Varian Clinac 600 C shows that the pulses come in batches; within the batch, the pulse repetition period corresponds to a specified frequency at the accelerator, while the repetition period of the batches differs from the specified frequency. Dose control in the pulses showed its 5 % excess over the average value during the first 2.5 s of the accelerator operation, whereas during the last 2 s, the dose reduction by 1.8 % was observed.Документ Results of industrial testing of carbide cutting tools by pulsed magnetic field treatment and the effect on the increase of the cutting process efficiency(Національний технічний університет "Харківський політехнічний інститут", 2021) Kovalev, V.; Klymenko, G.; Vasylchenko, Y.; Shapovalov, M.; Antsiferova, O.; Maiskykh, I.The task of increasing the efficiency of machining parts on heavy machines was determined, scientifically substantiated and solved by hardening a carbide tool the pulsed magnetic field processing (PMFP). The efficiency of machining of parts is understood as an increase in its productivity, a reduction in the cost and costs of tool materials, and an increase in instrument reliability. The working conditions of cutting tools at heavy engineering enterprises are analyzed. The wear resistance of carbide cutting tools, which have been strengthened by the PMFP, was investigated using forced test methods and modeling of the cutting process. The mechanism of changing the properties of a hard alloy under the action of a pulsed magnetic field is established. The main factors affecting the change in the wear resistance of a hard alloy under the action of a pulsed magnetic field are identified. The effect of pulsed magnetic field processing on the performance of carbide cutting tools under production conditions is investigated. The effect of hardening on productivity, cost of operation and instrumental costs is established. The interrelation of the parameters of the PMFP, the parameters of the process of machining parts and production efficiency is investigated. A statistical model has been developed that allows determining the productivity of mechanical processing depending on the properties of the tool material and the processing parameters of a pulsed magnetic field.
