Please note that we have 3 places for this workshop. Interested students who could not sign up, could check the registration regularly in case of cancellations. 

Hands-on experience with classic photomultipliers, oscilloscopes, scintillators, light guides, wavelength shifters and monochromators.
We start by characterizing the 1 photoelectron signal from the photomultiplier. With that knowledge we then measure the light yield of a plastic scintillator hit by a cosmic particle. We modified the setup to experience the advantages and disadvantages of introducing a wavelength shifter between the scintillator and photomultiplier. 
To disentangle the different efficiency involved we measure the quantum efficiency of the photomultiplier as a function of the wavelength.
