Out Quarknet Teachers had their first seesion experimenting with a coscmic ray test stand made up of two scintillators. Each scintillator was attached to a single PMT. A voltage of -900 Volts was applied and signals were observed using an oscilloscope.

First Cosmic ray scope pictures using PMT + Scintillator

First scope picture on a single detector


now look for a coincidence signal between two PMT detectors

Today our team of experimenters setup a discriminator to determine which of the PMT outputs woudld be used to define the presense of a charged particle passing through the scintillator
