Cathode ray tube
Cathode ray tube. Image 2 of 2. Demonstration showing how a beam of electrons can be deflected by a magnetic field, as seen in television cathode ray tube (CRT) displays. Here, electricity from the wires (left) is heating a cathode to produce a beam (blue) of electrons (also called a cathode ray), which is seen by the ionisation of the gas around it. Helmholtz coils (round) surround the glass tube and are providing the magnetic field to deflect the electron beam. This deflection of an electron beam is used to move the beam to create the images seen on a television CRT screen. See image T540/148 for this electron beam being used to produce green fluorescent light from the phosphor-coated area at right.

EDITORS COMMENTS
This print showcases the inner workings of a cathode ray tube (CRT), a fundamental component of television displays. The image captures an intriguing demonstration illustrating how a beam of electrons can be deflected by a magnetic field, which is crucial in creating the images we see on CRT screens. In this visually striking composition, electricity flowing through wires on the left side heats up a cathode, generating a vibrant blue beam composed of electrons. This electron beam, also known as a cathode ray, becomes visible due to the ionization of the surrounding gas. Surrounding the glass tube are Helmholtz coils, circular structures responsible for providing the necessary magnetic field to deflect and manipulate the electron beam. The photograph not only highlights key elements such as electrical currents and magnetism but also emphasizes educational aspects. It portrays an experimental setup within what appears to be a classroom or laboratory setting, showcasing its relevance in learning about physical phenomena and electrical engineering principles. Furthermore, this image serves as an excellent visual aid for students studying atomic physics or electronics. By observing how solenoids and Helmholtz coils interact with electron beams inside CRTs, individuals gain insight into essential concepts like thermionic emission and display technology. Overall, this mesmerizing print from Science Photo Library encapsulates both scientific curiosity and technological advancement in one frame while offering valuable educational insights into CRT displays' inner workings.
