you did not orient it perfectly between the two coils
This beam of electrons is emited by the cathode under voltage difference.
CRT is the answer..
optical charged plate attracted the beam. he concluded that the beam was made up of particles that have a new electric charge.
The fine-adjustment knob moves the body tube slightly to bring the image into sharper focus.
There is no gas in the bulb, only vacuum. The blue beam we see is a special flourid mix that sends out the blue stripe when the electron touches the paper and exidates the electrons in it.
Tube Lines's population is 3,500.
The Northern and Piccadilly lines are tube lines which have no branches at all.
This beam of electrons is emited by the cathode under voltage difference.
Tube Lines was created on 2002-12-31.
CRT is the answer..
Video the presentation and then upload it to You Tube. When you are videoing it, make sure it is on a correct kind of monitor, ideally on a laptop. Otherwise you will see lots of lines appearing on the video of the Powerpoint show.
Its a Square hollow section its a regual beam that is hollow.. in other words a metal tube beam.
Depends on the characteristics of the tube. Coat the interior surface with a (perfect) mirror finish, and the laser beam will continue quite happily. Fill the tube with either multiple fiber optic strands, or build it like one huge fiber optic strand and the beam will continue as well.
CRT
four coils are used to create a magnetic field to deflect the electron beam in two dimensions.

CRO consists of a cathode ray tube which is having the vacuum conditions . The electron beam is emitted by a cathode at the rear end of the tube. This beam is accelerated and focused by one or more anodes. The rays then strike the front (other end) of the tube and produces a bright spot on the phosphorescent screen
