DEMONSTRATION OF CHANGES IN THE STRUCTURE OF CRYSTALS UNDER THE ACTION OF TORSION RADIATION ON THE MELT OF METALS
Preliminary exploration work demonstrating a change in the crystal lattice under the action of a torsion field on a metal melt was obtained in the works under the supervision of the Director of the Scientific Research Institute of Electrophysical Surface Problems in St. Petersburg, Academician of the Russian Academy of Natural Sciences, Ph.D., Professor G.N. [13,14].
The experiment was built according to the scheme, as indicated in Fig.3. One of the main elements of the experimental stand (Fig. 3) was a field emission projector (2) with a resolution of -20E, an increase (2h 3) • 10 5 and a working vacuum of 5 • 10 -9 Torr.

To ensure the operation of the projector, a high voltage source of 0h50 kV (3) with a voltmeter (5), a heating source (4) of a tungsten cathode (1) with an ammeter (7), and an ammeter (6) were used.
In experimental studies, the emission image of the cathode is first fixed (Fig. 4a). In the second phase, the polarity of the high-voltage supply voltage (3) of the projector (2) is reversed using the switch (13). Due to cold emission from the anode, the cathode is heated. Even when the cathode is heated for 10 hours, the structure of the cathode surface remains almost unchanged (Fig. 4b).
However, if the cathode is heated for only 1 hour with simultaneous action of torsion radiation at a frequency of 0.1 MHz generated by a torsion generator (8) (Fig. 4d), then the cathode emission pattern changes dramatically (Fig. 4c). Under the action of a torsion field, two brightly emitting areas appear on the cathode (two spots in Fig. 4c) in the <001> direction. The variation of the auto-emission projector modes and the time of exposure to the cathode by torsion radiation did not change the observed picture. This is clearly seen from the results of table 1.
It was suggested that the torsion field can affect the transfer processes during the decomposition of submicrostructures grown on the surface of a microcrystal in an electronic field after high-temperature heating .
