Observation and investigation of anomalous X-ray and thermal effects of cavitation

The anomalous X-ray and thermal processes associated with cavitation of fast liquid jet in a narrow channel and in free space outside the channel are considered. It has been found that the output of the channel and the initial part of the free jet are sources of intense X-rays, generation of which is connected with shock waves. The energy of X-rays (ħω ≈ 0.7–5.0 keV) depends on the type of atoms on the radiating surface. Formation of shock waves and X-rays is accompanied by generation of undamped high-frequency thermal waves.
