1. Characterization of GEM detectors, and the way there… Rodrigo G. Cortiñas CERN, Summer Student Program 2013 Universidad de Buenos Aires, Facultad de Ciencias exactas y Naturales.

2. Gas Electron Multiplier

3. Variables Pitch Shape of holes Applied voltage Radiation intensity Gas composition (Ne, Ar…) …

4. Measurements Stability

5. Measurements Stability

6. Measurements Stability

7. Energy Resolution (~ momentum or ~wave number of striped electrons)

8. Output=f*g=Signal*Noise

11. Output=Signal*Noise

12. (“fallacy of the converse”)

14.  Why GEM?  What is a single wire?  Which radioactive sources do we use for testing?  Where does the Power Bar live?  Security measurements for radiation  Why two Gaussians in energy resolution?
