Dear Old Timer,
Do you have a subscription to Nature? Have you read the entire article ? I went to Nature and they didn’t mention cavitation in the press release, just
Gamma-rays from harmonically resonant betatron oscillations in a plasma wake.
I am not sure that I completely understand your overall objections to the report in Science Daily, but even if the magnitude of results is less than the reporter
stated, it still appears that gamma rays were produced. There have been multiple studies that standing sound waves in a fluid that produce non inertial cavitation
that upon collapse of the resulting “bubble” produce a very large shock wave and high temperature. This feature has been used to good effect in commercial hot water heaters. My original suggestion was that the concept of cavitation in a plasma being oscillated by ultra short laser bursts might lead to “ignition” . We know that various techniques are getting close as we better understand the nature of plasma. I know of a professor who has taken ultra slow photographs of what happens ( think pico seconds ) when the “bubble” collapses and he suggests that the phenomena is chaotic and erratic which is to be expected. It suggests that replication of effects will necessarily be affected. Until we better understand the parameters, the effect alone will not be worthwhile. But I think producing gamma rays with a hand held device is an achievement…
