Fine Beam Tube – P318001
Product Name: Fine Beam Tube
Model / Part No.: P318001
The Fine Beam Tube P318001 is a laboratory educational device designed to demonstrate the behavior and motion of electrons in a controlled vacuum environment. It is commonly used in physics laboratories for experiments involving electron beams, magnetic fields, and the charge-to-mass ratio (e/m) of the electron.
The tube contains an electron gun that produces and accelerates a narrow beam of electrons. When a magnetic field is applied, the electron beam can be deflected into a circular path, allowing students to study the relationship between electron velocity, magnetic field strength, and the radius of the electron path.
Specifications shown on the product label:
- Anode Voltage: 200–300 V
- Focus Voltage: 50 V
- Filament Voltage: 4–10 V
Applications:
- Electron beam experiments
- Measurement of electron charge-to-mass ratio (e/m)
- Demonstration of electron motion in magnetic fields
- Physics laboratory and educational demonstrations
