SUMMARY

The forum discussion centers on the effectiveness of a DIY muon detector and the challenges in distinguishing muon hits from background noise. Users reference specific experimental setups, including those detailed on Instructables and Physics Open Lab, which suggest that while detecting muons is feasible, confirming their presence amidst noise is complex. Key factors influencing detection include the use of water and heavy materials, which can affect hit rates, but do not necessarily confirm muon detection. A coincidence detection setup is recommended as a potential solution to improve accuracy.

PREREQUISITES
  • Understanding of Cherenkov radiation and its relation to muon detection.
  • Familiarity with scintillator materials and their properties.
  • Knowledge of coincidence detection setups in particle physics.
  • Basic principles of particle interactions and background noise in detection systems.
NEXT STEPS
  • Research the principles of Cherenkov radiation and its application in muon detection.
  • Explore different scintillator materials and their effectiveness in detecting muons.
  • Learn about coincidence detection setups and how they enhance particle detection accuracy.
  • Investigate methods to differentiate between muon hits and background noise in experimental setups.
USEFUL FOR

Physics enthusiasts, hobbyist experimenters, and educators interested in particle detection and the practical applications of muon detection technology.

Hello

I found this video on YouTube,


It seems that most of the counts are noise of the PMT...

Thank you for your time.

Regards.

Is there a question in there?
 
Hello

Sorry, I forgot to repeat the question in the title. Is the homemade experimental setup detecting Cherenkov from muons, or it is detecting other things?

Thank you for your time.

Regards,

I don't think it's possible to answer your question from a movie clip.
 
Getting hits from muons is not hard, figuring out which of the hits are muons and which hits are something else is much harder.

That was my doubt: in principle, they prove that part of the hits are muons because:
-- The rate of hits increase if water is used (instead of air)
-- The rate of hits increase if a heavy material is used above the detector (in principle, this material will have more probability of interaction with muons, and the detector will notice the secondary particles).

Do these two tests confirm that part of the hits are caused by muons?

And by the way... why is harder to differ muons from something else?

Thank you for your time.

Regards.
 
Water (as shielding?) shouldn't increase the muon rate.
Based on These slides, 17 meter of water reduce the flux by a factor 10 (they discuss neutrons, but induced by muons). You need a lot of water or other materials to get relevant shielding.

It is generally difficult to find out what produced a hit. You need a coincidence detection setup, an energy measurement, or something similar.
 
Hello

Sorry, I said it wrongly:
-Changing the scintillator material (instead of air, water), the rate of counts was doubled.
-Adding few blocks at the top of the detector, as a shielding, the increase of counts increased (in the video is said that this may have sense).

Ok, maybe the easiest way is a coincidence detection setup.

Thank you for your time.

Regards.
