This is ground level data to compliment the data to be collected at altitude during trans-atlantic flight from UK to USA on 30/7/2026. If that data is successfully collected, then…
Yes — but with an important caveat: the stock CosmicWatch v2 firmware was not originally designed to reliably do full SD logging and OLED display updates “in parallel” without trade-offs,…
Right — this is the bit that trips most people up, but it’s straightforward. CH340 is not a “USB drive”. It’s the USB-to-serial chip driver your Arduino Nano clone uses…
# NonOfficial-StuffForCosmicWatchMuonDetectors Extra code and stuff I (Jotham Gates) have made/adapted for Spencer Axiani’s Cosmic Watch Desktop Muon Detector V2 The official website can be found at (http://www.cosmicwatch.lns.mit.edu/) The official…
What format does Arduino use for SD cards? Arduino (including CosmicWatch-style data loggers) doesn’t define its own SD format — it relies on the SD card being formatted in a…
I have accessed Jotham Gates Githib site – how do I now load his firmware onto my Cosmic Watch v2 muon detector? Good — if you’ve already reached Jotham Gates’…
Not a stupid suggestion at all. Temperature really does matter for detectors like the PicoMuon detector, especially because the silicon photomultipliers (SiPMs) inside produce thermal noise (“dark counts”) that rises…
This was originally posted by Andrew Thomas on muondetector groups.io mailing list 26/5/2026: The PicoMuon will behave oddly and even stop working if it gets too hot. This usually manifests…
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…
