It was at this time that Plücker asked Geissler to make him an apparatus for evacuating a glass tube. In 1847, he began research on the behavior of crystals in a magnetic field, establishing results central to a deeper knowledge of magnetic phenomena. In the 1840s, he turned away from mathematics and concentrated his attention on physics. Julius Plücker, on the other hand, was a famous German mathematician who made fundamental contributions to analytic and projective geometry.

It was here that he worked as an instrument maker for the production of physical and chemical instruments. Eventually, in 1852, Geissler decided to settle down in a workshop of his own. Born in Igelshieb, Thuringen and descended from a long line of craftsmen in the Thüringer Wald and in Böhmen, Geissler had worked as an instrument maker with his brothers throughout Germany and the Netherlands for many years. The history of cathode ray tube can be followed back to at least 1854 when the skilled German glassblower and mechanic Johann Heinrich Wilhelm Geißler - also known as Heinrich Geissler - was asked to design an apparatus for evacuating a glass tube by Julius Plücker, the professor of mathematics and physics at Universität Bonn (University of Bonn). This puts a serious limit on the size and the shape of a CRT display, which explains why LCD and LED eventually left CRT in the dust.

Because CRTs require thick glass to safely and effectively create and maintain a vacuum, cathode ray tubes weigh quite a bit.

These storage tubes are CRTs made to hold onto an image as long as there’s power being supplied to the tube.

While we think of CRT as display technology, it can also be used for storage.

In 1855, Heinrich Geissler was awarded a gold medal by the Exposition Universelle (World Exhibition) in Paris due to his excellent work on fine glass - including what would eventually be known as the cathode ray tube.

The level of demonstration of high school or university class is all that I am interested in for using the Crooke's Tube.Inventor of the cathode ray tube. I have a 300 volt power supply already and have not encountered any problems using it. It looks like it has an operating voltage of max at 5000 volts but there are versions that operate at less than 300 volts. The Crooke's Tube seems to be the thing I want.

Remember that I am NOT looking for a tube to make X-rays.

They apparently covered TV cathode ray tubes were covered in lead glass. I admit that I did not know that TVs and O-scopes did produce X-rays the whole time. It seems that a beam of electrons with energy less than X-rays should be possible to make-just lessen the accelerating voltage low enough that the electrons cannot make X-rays when they hit their target. I know, at least, conceptual, how the X-rays are produced and can add more if needed.īut I don't need (or want) the electrons to have a high energy to produce the X-rays, I just want the beam of electrons. If the electrons have high enough energy, they will produce X-rays. X-rays are produced when electrons are accelerated to high speeds and smash into target metal. Can someone help me to find a website where I can buy non-X-ray cathode ray tubes where the electron beam is visible, if such a tube is even possible? If such a cathode ray tube does exist, would the glass be transparent so that someone could see the electron beam? I couldn't tell from my internet searches if cathode ray tubes in TVs and oscilloscopes had transparent casings or not. It seems that non-X-ray cathode ray tubes should exist, since TVs and Oscilloscopes were built using them for decades and I seriously doubt the manufacturers would sell TV's and oscilloscopes that would produce X-rays in the family living room housing the TV. I haven't had much luck on the internet finding such cathode ray tubes or I don't know what I am looking at when I scan the internet through all the different cathode-ray tubes that exist. However, I don't want to deal with X-rays, and would prefer to obtain cathode tubes that cannot produce X-rays at all. I would like to obtain cathode-ray tubes for deflecting electrons with a magnet.
