X-rays from a homemade discharge tube

(Adolf Cortel, June 2019). The video demonstrates how x-rays can be produced from a simple and homemade discharge tube. The experiments are dangerous because of the very high voltages as well as the x-rays produced. Although the purpose of beginning these experiments was to check the conditions at which a discharge tube can give x-rays, I have to confess that generating x-rays and taking radiographies with homemade equipment ( if the definition of homemade includes a vacuum pump amd machining metal with a lathe) has been quite a challenge. I have tried to protect myself in the best possible way, but since the dangers involved are actually very serious and perhaps some people is not fully aware of them I have to discourage replicating these experiments.
The video shows that x-rays intense enough to take radiographies are produced only after the vacuum pump has been working for two hours. Of course, this time can be shortened using a better pump. Another important point is the electrical behavior of the discharge: the discharge tube works almost as a short of the HV supply and is a low power supply is used the voltage in the tube drops dramatically to a value to low to produce x-rays.
I have borrowed the music (Aguas the março) from the Sant Andreu Jazz Band. Of course I do not have any right on this music, but being a deep admirer af this band I hope that they will forgive this infraction.
