The particles originate from the Cathode in the neck of the tube. They are liberated by a heater. The electrons thus liberated are attracted by the Anode, by applying a high voltage to it.
In a CRT there are several anodes, the largest and biggest is formed by a coating inside the tube towards the screen. This attracts and accelerates the electrons in a stream of particles known as a 'cathode ray'. They carry on in a straight line, once accelerated, until they hit the screen and cause a phosphor coating to glow, on the inside surface of the screen.
The cathode ray can be bent from it's course, by using electromagnets arranged around the neck of the tube.
A diode cannot conduct in reverse bias because of the way it was made. If the question is asking about a thermionic vacuum tube diode, the electrons produced by the heated cathode of the tube can only move in one direction: from the cathode to the anode - but only for as long as the anode is positively charged. The reason is that, if the anode is made to be positively-charged, it ATTRACTS electrons - which are negatively charged - from the cathode, so a current flows from cathode to anode in the "normal" biased direction because of the physical fact that UNLIKE CHARGES ATTRACT ONE ANOTHER. If the anode is made to be negatively charged, the electrons won't go to it because of the physical fact that LIKE CHARGES REPEL ONE ANOTHER, so no electrical current can flow from the cathode to a negatively charged anode. (In fact no electrical current can ever flow from a negative anode to the cathode for an entirely different reason: no anode of any normal thermionic vacuum tube was ever designed and made to "produce" electrons in the way that a heated cathode produces them!) To be able to "produce" electrons and let them fly to the positively charged anode, the cathode must be able to receive some more electrons to replace all the ones that have left the space around the cathode. That "supply of more electrons" is called an electric current. That current does not come from nowhere - it has to comes from a source, such as a battery or a generator - and the electrons which reach the anode must then be conducted back to the battery or a generator so that they complete a full electrical circuit by traveling along the wires which connect the source to the diode. Similarly, because of the way it was made, a semiconductor diode behaves in just the same way as a vacuum tube diode: electrons can flow from the negative end to the positive end of the semiconductor diode but not the other way around. The actual reason why a semiconductor diode works like that is very much more complicated to explain than for a vacuum tube diode. Put very simply, a semiconductor diode has the kind of materials inside it that will only allow electrons to flow one way. If a voltage is applied to the diode the wrong way round (called reverse bias) practically no current can flow through the diode.
in a CRO ,fast moving electrons coming from cathode tube strikes the screen .This is seen as a single dot,but for viewing a waveform it is required that the electrons should move both horizontally as well as vertically. For that purpose a horizontal deflection plate is provided in the cro. This deflection plate is supplied with voltages , so that the electrons passing through these plates get deflected horizontally.due to alternating voltages these electrons deflect right & left very quickly, that we humans fell it is a straight horizontal line due our perception. THE voltages is provided by sweep generator,which produce ramp voltages WHICH IS AMPLIFIED & PROVIDED TO HORIZONTAL DEFLECTION PLATES in a CRO ,fast moving electrons coming from cathode tube strikes the screen .This is seen as a single dot,but for viewing a waveform it is required that the electrons should move both horizontally as well as vertically.

For all practical purposes, we are still limited by wireswhen we need to move electrical energy.

One piece of evidence is the observation that cathode rays are deflected by electric and magnetic fields, indicating they carry charge. Further evidence comes from the fact that cathode rays produce X-rays when striking a target, which is consistent with the behavior of charged particles like electrons. Additionally, the ratio of the charge to mass of the particles in cathode rays was found to be the same as that of electrons.
Copper ions will move towards the cathode (negative electrode) and iron ions will move towards the anode (positive electrode) in an electrolytic cell.
Copper ions in a solution typically move towards the cathode electrode during electrolysis, as they gain electrons and are reduced to form solid copper. This process helps to plate the cathode with a layer of copper metal.
A cathode is an electrode through which electrical current exits a polarized electrical device. Its opposite is the anode, through which electrical current enters the electrical device. Positively charged ions, called cations, move towards the cathode, while negatively charged ions, called anions, move towards the anode.
because Thomson saw the ray move from the cathode to the anode so the particles have negatively charge
Ions are released at the anode during oxidation, and they move towards the cathode through the electrolyte. At the cathode, the ions gain electrons and are reduced. This process results in the transfer of ions between the cathode and anode.
Because an electron carries a negative charge and in electricity, opposites attract. Particles with a negative charge will be drawn to the positive charge in the cathode tube.
Cathode rays are negatively charged particles that move in curved paths in the presence of a magnetic field. The direction and curvature of the cathode rays can be controlled by adjusting the strength and orientation of the magnetic field. This phenomenon is known as the magnetic deflection of cathode rays and is used in devices like cathode ray tubes.
Anode rays are also known as canal rays because they were discovered to be positively charged particles produced in a cathode tube when the cathode rays strike a gas at low pressure. The particles travel in the opposite direction of cathode rays and move towards the anode or positive electrode, hence the name "anode rays."
Scientists concluded that cathode rays were negatively charged particles that carried momentum. They inferred this from the movement of the paddle wheel, which indicated that the cathode rays possessed kinetic energy and could transfer their momentum to the wheel as they collided with it.
