How do you count muons? #79

Open agnessap opened 2 years ago

Hi, I've made the muon detector, and am now trying to count how many muons there are. I've tried using some of the code which is on the CosmicWatch GitHub, but I don't quite understand how I can "count" how many muons that are detected. I would appreciate any help or clarifications :)

Hi,

There are primarily two ways to improve the purity of the muon sample that you are collecting.

  1. If you have two detectors, you can connect them through the 3.5mm cable. This sets them up in coincidence mode. With this, you can get to ~99.9% purity (if you are a under >6” of concrete to shield from the electromagnetic component of the shower).

  2. If you have a single detector, you can reduce the background by increasing the threshold (see the attached image, coincident events are mouns). Although this only gets you to a ~60% purity.

If you would like to read more about how this works, please see Section 5.3.1 of the PhyiscsPaper.pdf in the Github repo. If this does not answer your question, please let me know.

Thanks,

Spencer
