What is happening here?

I folks. I marked this a 'something weird'.
Can someone explain how this pattern is generated?Posted

Interesting .. muon detector is light up like christmas tree, but there is not a single track visible

Go home ATLAS, you're drunk! 😄
It was no sim actually 😉Posted

Good one! This is a fun event. What has happened is that a very energetic cosmic ray (muon) has showered in the atmosphere or rock above ATLAS creating hundreds of lower-energy muons traveling in the same direction at the same time. You've found a particle from outer-space (probably a supernova!), whose energy is greater than we can create at the LHC!
I've attached a zoomed-out slice view, where I've also drawn the short muon "segments" found. (They usually don't make full tracks since they don't line up with the proton collision point.)https://drive.google.com/file/d/0B4ni16QPwtZ6VnlnQXA1MU16T28/view?usp=sharing

Heyyy! Is this one of our first really cool finds? 😃

Thanks for the explanation Andy!
Wow, that bugger must have packed a punch when the detectors light up like that! I just read that those muons can travel through several kilometers of solid rock without problem and aren't all that uncommon. I wonder how often they are detected by (or interfere with experiments) at ATLAS. Doing this is so much fun 😃Posted

I feel a #dailyzoo coming up ! 😄
PS : If you see something really cool, you can always mention it for the "Daily Zoo : something awesome from the Zooniverse every day" by using the #dailyzoo 😄
