Am I getting correct muon counts with my two muon detectors at LRO in coincidence mode? Do other sources of muons affect the detectors from the ground and do we need to take account of these?
Dr Jonathan Lister: We do get upward directed muons their source being radioactivity from soil, rocks and building materials and once the gamma rays enter the scintillator they interact with…
Measuring data at 102.1 degrees elevation with Ptarmigan Array (Milky Way Hydrogen Map)
It appears my map with the extra 96.6 degrees elevation readings is now close to maximum I can achieve (see plot on previous post). I am going to try adding…
Results of adding 96.6 degrees elevation (beyond Zeinith by 6.6 degrees) to my galactic hydrogen map
Which muon detector should be on top when there is pair of muon detectors on top of each in coincidence mode (master/slave configuration)?
I have been sent the following answers to the above question: Andy 1. From Dr Spencer N. Axani, of the CosmicWatch project: Hi Andrew, Thanks for the email. It cannot…
Adding bricks to point the Ptarmigan Array beyond the Zenith 21/12/2023
Today I decided to find out what happens when I take the array to point other side of Zenith (ie > 90 degrees). Will it just give same data as…
