Recorded the 28/07/2024 above the ground near sea level, we can see a lot of electromagnetic showers. Not many protons or violent reaction but some are interesting. See 34:04 particularly and for connoisseurs 01:08:06.


00:46 Proton
01:24 Possibly a triplet with ejection of an e- at left in the beginning
03:09 Electromagnetic (EM) shower (e-, e+)
03:13 not a proton to me, maybe muon
04:12 negative particle with high energy, make a collision with a nucleus then is deflected losing a great quantity by Bremsstrahlung and thus is deflected by the B field and eject 2 e- at the end of range.
04:20 at far left, a particle is well deflected by B but the other goes straight. Electrons are deflected towards right according to the direction of B field. So the deflected particle is a positon. This mean that the event is a pair creation where the electron had a good amount of energy during the process because it don't follow the B field.
04:25 3 parallel lepton (e- or e+) from a EM event coming from the bottom and going upward. The particle at left is deflected at the end of its range.
09:50 double pair creation
09:54 triplet with the ejection of a low energy electron at the beginning
09:56 photodisintegration detailed here https://www.cloudylabs.fr/wp/interact...
12:07 double triplet creation
12:38 localized ancien EM shower
17:21 fast particle
19:11 2 fast particles with a possible nucleus collision at one end.
27:07 double pair
28:11 massive particle, not sensible to the magnetic field, with a possible nucleus collision at one end. The straggling at left indicate that the particle have a low energy and is not deflected by B, so this is not an electron so the event is not a pair creation. A proton won't diffuse so much. I'm not sure.
32:15 a fast particle not deflected by B and a low particle at top right deflected.
34:04 photodisintegration detailed here https://www.cloudylabs.fr/wp/interact...
34:24 Fast electron colliding with a nucleus at the end of range and losing a great amount of energy by Bremmsstrahlung thus expecting a high straggling. But the collision don't appear so frankly. It can be also the disintegration of a muon into an electron of very low energy, the neutrino taking almost all of kinetic energy.
39:38 The heart particle ! In fact, a pair creation. The electron goes upward and expect 2 collisions.
40:21 Delta ray (ejection of electron) at 90°
42:15 The squared particle
42:28 pair creation and deviation of an electron
44:38 a fast proton !
49:11 Nice electromagnetic shower
54:57 a fast particle maybe a proton.
01:06:20 A rare event, a head on collision of an e+ to an e- taking the momentum and deflected in another direction. See : https://www.cloudylabs.fr/wp/les-proc...
01:08:06 Same previous event.
