  1. Detecting Cosmic RaysAn inexpensive portable detector By: Danny Franke Quarknet 2004

  2. LBNL Detector http://www.lbl.gov/abc/cosmic/

  3. Scintillators Scintillators are materials which emit light when they interact with charged particles. Usually a type of plastic that is doped with small amounts of aromatic hydrocarbons. (Polyvinyltoluene)

  4. Photomultiplier Tubes • Photon Detectors • Operate on photoelectric effect • Amplification is obtained by a sequence high voltages applied across dynodes

  5. Completed counter

  6. LBL Electronics
