A muon passing through the atmosphere is very likely to interact many times electromagnetically, but very unlikely to undergo a major nuclear interaction or be stopped outright. The key point…
Yes — muons are electrically charged particles. A muon is similar to an electron but much heavier (about 207 times the electron’s mass). There are two types: The elementary charge…
1. Basic physics Cosmic-ray muons at ground level: Approximate stopping power in lead: dE/dx ≈ 1.5 to 2 MeV g^-1 cm^2 Lead density: rho_Pb ≈ 11.34 g/cm^3 So energy loss…
The following has come from ChatGPT. (An ASCII text version of this post is available for people who have difficulty reading this page at https://www.astronomy.me.uk/calulat8ng-attenuation-of-muons-in-lead-ascii-text-version) Assessing the results from LRO…
This experiment was suggested to me at the last SARA online meeting. Here are the results – I started with zero and build up to 5, and to confirm went…
I have successfully replicated the experiment in the Comic Watch manual showing change in rates measured as result of radioactive test source (radioactive rock from ebay) on top of detectors…
Two detectors in coincidence mode, one on top of other. Radioactive rock test sources from ebay – large and small ones – plus I have some pieces of lead which…
Untested advice from ChatGPT: The following comes from ChatGPT. I am unable to verify the content from personal experience. I have entered this advice onto this blog as part of…
Short answer: no—those experiments are not actually measuring anything travelling faster than light. When Cosmic Watch–style muon setups give “superluminal” results, it’s almost always due to measurement/systematic effects rather than…
The observations from the balloon flight can be understood in terms of how muons are both produced and lost as cosmic radiation passes through the atmosphere. When high-energy cosmic rays…
