Particle Detector: How Many (e-, ion) Pairs Are Created?

Click For Summary
SUMMARY

The discussion centers on calculating the number of electron-ion pairs generated when a particle with an energy of 900 keV is fully absorbed in a detector. The calculation shows that each pair requires an average of 30 eV, leading to a total of 30,000 pairs created, confirmed as correct by participants. This straightforward division illustrates the relationship between energy absorption and pair production in particle detection.

PREREQUISITES
  • Understanding of energy units (keV and eV)
  • Basic knowledge of particle physics and pair production
  • Familiarity with particle detectors and their operation
  • Mathematical skills for division and unit conversion
NEXT STEPS
  • Research the principles of pair production in particle physics
  • Explore the efficiency of different types of particle detectors
  • Learn about energy loss mechanisms in matter
  • Investigate the impact of varying energy levels on pair production rates
USEFUL FOR

Physicists, engineers working with particle detectors, and students studying particle physics who want to understand energy absorption and pair production dynamics.

A particle with 900 keV get into the detector and was fully absorbed, how many pair of (e-, ion) are created if one pair required an average of 30 eV.?

900000/30 = 30,000
is this a right answer?
