That scanner board is Z axis protection, if anything breaks the beam, it would stop moving down. Or if the board is hit first, the switch would also disable the Z axis.

Just my 2 cents. I worked in a metal finishing shop (electroplating) about 20 years ago. We used an X-ray fluorescence device similar to measure deposited (plating) thickness. This method superseded beta-back scatter for measuring. The equipment was very expensive. Tens of Thousands of dollars. They were very accurate. On special parts we measured with micro-cross section (cut parts in half and measure plating thickness under a microscope) to verify thickness.

For some reason I thought that X-ray tubes have rotating parts inside them, but I don't see them in the video. Did you take them off for the demo, or are they just not used in this kind of tube (only on some other kind e.g. higher voltage), or are they there and I'm just not watching closely enough?

I've never heard of X-Ray tubes with moving parts. Just the high voltage and the low gas pressure inside the tube are all it needs.

Some high power tubes use a conical rotating anode to spread out the power dissipation at the target. Less common nowadays with better detectors
@Nitrxgen
10 жыл бұрын
You are right. Some older tubes will feature a spinning tungsten anode inside to keep cool via heat dissipation as they get very hot from the electron gun. Tungsten's melting point is 3,400 Celsius and conducts heat incredibly well. In some cases, the tungsten in xray high power tubes have been known to melt so it helps to increase the apparently surface area to the exposure of electrons, and in turn helps save a lot of bother with external cooling.

the source of gamma he was using is an old fiestaware plate, that has uranium oxide in the ceramic glaze. it is a very low level source of gamma radiation and is safe to handle. also the sensor he is using is very sensitive to gamma radiation. some homes in certain parts of the uk need to have a ventilated basement due to naturally occurring radon gas coming out of the ground!!
