Cathode Ray Maltese Cross Manufacturer,Supplier and Exporter in India

Product Code : SCL-PLE-11841

The Cathode Ray Maltese Cross by Scientifc Equipment is an educational physics laboratory apparatus designed to demonstrate the straight-line travel of cathode rays, electron beam behavior, shadow formation, vacuum tube operation, and the particle nature of cathode rays. It is suitable for advanced school physics laboratories, college science labs, electronics demonstrations, atomic physics lessons, and supervised teacher-led experiments.

This apparatus helps students observe how cathode rays travel in straight lines and cast a shadow of the Maltese cross on a fluorescent screen. It supports practical learning of electron beams, cathode ray tube principles, discharge tube experiments, high-voltage physics, and early discoveries related to electrons.

Product Description

In a Cathode Ray Maltese Cross tube, a Maltese cross-shaped obstacle is placed in the path of cathode rays inside a partially evacuated glass tube. When the tube is connected to a suitable high-voltage power supply, cathode rays move from the cathode toward the fluorescent screen. The cross blocks part of the beam, producing a visible shadow on the screen and showing that cathode rays travel in straight lines.

The Scientifc Equipment Cathode Ray Maltese Cross may include a glass discharge tube, cathode and anode electrodes, Maltese cross target, fluorescent screen, high-voltage terminals, tube support, connecting leads, and demonstration accessories depending on product configuration. It is designed for supervised educational and laboratory demonstration use only.

FAQ

1. What is Cathode Ray Maltese Cross used for?

It is used to demonstrate that cathode rays travel in straight lines by showing the shadow of a Maltese cross on a fluorescent screen.

2. Is this apparatus suitable for school physics laboratories?

Yes, it is suitable for advanced school physics labs, college science labs, STEM classrooms, and teacher-led demonstrations with proper supervision.

3. What principle does the Maltese cross tube demonstrate?

It demonstrates that cathode rays travel in straight lines and can be blocked by an obstacle, producing a shadow on a fluorescent screen.

4. Does the apparatus require high voltage?

Cathode ray tube demonstrations generally require a compatible high-voltage power supply. Exact voltage requirements depend on the product configuration and tube rating.

5. Can students operate this apparatus independently?

No. Students should only observe or assist under trained teacher or laboratory instructor supervision because the apparatus may involve high voltage and a glass vacuum tube.

6. Why does the Maltese cross shadow appear?

The Maltese cross blocks part of the cathode ray beam. Since the beam travels in straight lines, the blocked region appears as a shadow on the fluorescent screen.

7. What safety precautions are important?

Important precautions include using insulated high-voltage leads, checking the glass tube for damage, avoiding contact with terminals, switching off before adjustments, and using a safety screen if required.

8. How should the Cathode Ray Maltese Cross apparatus be stored?

Store the apparatus in a clean, dry, and protective place away from moisture, dust, chemicals, heat, impact, and rough handling. Keep leads and accessories organized.
