Why is perforated cathode used in the discovery of anode rays?

Click For Summary
SUMMARY

Perforated cathodes are utilized in the study of anode rays to allow the passage of electrons or protons, which are absorbed by the electrodes. The holes in the electrodes enable these particles to ionize the surrounding gas, resulting in the generation of positive gas ions that migrate towards the cathode. This mechanism is crucial for understanding the behavior of anode rays in experimental setups.

PREREQUISITES
  • Understanding of basic particle physics concepts
  • Familiarity with ionization processes in gases
  • Knowledge of cathode and anode functions in electrical circuits
  • Awareness of experimental setups involving gas discharge tubes
NEXT STEPS
  • Research the principles of gas ionization and its applications
  • Explore the role of cathodes and anodes in electrical discharge experiments
  • Study the historical significance of anode rays in atomic theory
  • Investigate modern applications of perforated electrodes in plasma physics
USEFUL FOR

Students of physics, researchers in particle physics, and educators looking to enhance their understanding of anode ray experiments.

Homework Statement
Why is perforated cathode used in the discovery of anode rays? Is there a hole in anode through which cathode rays pass and what causes the glow behind cathode and anode electrode? Is this glow due to the rays?
Relevant Equations
There are no equations.
I really tried to solve it a lot and the info that I gathered is :

Electrons or protons can be ABSORBED by cathode or anode so there must be some hole in the electrode for the rays to pass.
These electrons ionize the gas and those positive gas ions move towards cathode.
