Using radioactive test source on UKRAA Cosmicwatch muon detectors
Admin
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…

How to check data collection service is running/start service/stop service on UKRAA PicoMuon Detector
Check GetDataRawACM0 service is running sudo systemctl status PicoMuonACM0.service sudo systemctl start PicoMuonACM0.service sudo systemctl stop PicoMuonACM0.service sudo systemctl enable PicoMuonACM0.service sudo systemctl disable PicoMuonACM0.service . Screenshot below is the…
Pico Muon Data Sharing Website
Hi Andrew I have attached two files (accessible via link at bottom of this post), which need to be copied onto the RPi. I have changed their names because a…
What limit does Cosmic Watch muon detector use to include an event on the two coincidence detectors as being detected?
For CosmicWatch in hardware coincidence mode, the criterion is actually very simple and quite tight: Hardware coincidence (detector-to-detector cable) 👉 So the effective “limit” is: Two pulses must occur within…
Muon hodoscopes
A muon hodoscope doesn’t just count how many muons hit it — it also tells you which direction they’re coming from, with pretty good accuracy. That turns out to be…
My muon detector, and a number of other people’s around the world, has shown significant dip in muon detector on 20 January 2026. A CME hit the atmosphere of Earth on 19 January 2026. Are the two related?
Dip in Muons detected on the UKRAA PicoMuon detector at LRO 20/1/2026: Yes — they’re very likely related. Here’s why: 📡 What happened on 19–20 January 2026 🌍 How CMEs…
How much uranium is it legal to own without licence in UK?
How much uranium is it legal to own without licence in UK? Short answer: there isn’t a simple mass limit — UK law controls radioactive activity (becquerels), not kilograms. Small…
Sampling / time resolution (“sample time”) and timing behaviour of the CosmicWatch muon detector.
Here’s what I found on the sampling / time resolution (“sample time”) and timing behaviour of the CosmicWatch muon detector: Key timing / sampling facts Summary & caveats So, in…
Grafana Dashboard for my pair of UKRAA Cosmicwatch Muon Detectors still shows cyclical variation in levels every few hours
I moved them away from power sockets and still show this cyclical variation below.
