THE QUICK HISTORY OF COSMIC RAY MANTHE BIRTH OF AN EXTRAORDINARY PARTICLE… • Wilson suspected the cause of the “residue” conductivity of the atmosphere might be condensation tracks on the nuclei-ions.
A QUICK HISTORY OF COSMIC RAY MANTHE BIRTH OF AN EXTRAORDINARY PARTICLE… GERMAN SCIENTIST, VICTOR HESS AND HIS BALLOON WOW!!!
A QUICK HISTORY OF COSMIC RAY MANTHE BIRTH OF AN EXTRAORDINARY PARTICLE… • In 1912, Victor Hess took a radiation counter (using a gold leaf electroscope) on a balloon flight. • Traveling 17,500 feet without oxygen, he observed the radiation increase in his balloon climbed.
THE REBIRTH OF COSMIC RAY MAN
THE MUON… THE REBIRTH OF COSMIC RAY MAN!
By the time Cosmic Ray Man reaches the Earth’s surface, there are mostly muon’s and electron’s left…about 5/6 and about 1/6 (respectively). So the higher the primary energy, the more muons and electrons are on the ground.
