A perk of SARA membership that we can use the 20m Skynet dish. The angular size of the Andromeda Galaxy (M31) depends on how faint an outer region you include:…
Using medium-format lenses on a full-frame A-mount body like the Sony Alpha A99 is a niche but very enjoyable setup if you like manual focus, unusual rendering, and superb central…
For two identical horizontal scintillators of size 5 x 5 cm, the coincidence rate drops as detector spacing increases because the allowed angular acceptance narrows. A useful estimate is: tan(theta_max)…
Yes — there have been a few measurements and discussions of temperature effects in CosmicWatch-style scintillator/SiPM muon detectors, though not many formal dedicated studies. The main effect is usually not…
There are several major types of cloud chamber and related particle-track detectors. They all work by making charged particles visible as trails. 1. Diffusion cloud chamber This is the most…
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…
Short answer: no — not reliably, and usually not at all. When you’re using an EQ6 mount (like the Sky-Watcher EQ6-R Pro) through ASCOM Platform and Stellarium, the system does…
This is a possible but untested solution. Make sure you tighten clutches before turning off your motors so that your antenna does not drop and hit ground or mount. Also…
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…
