First waveforms in NEW

NEW is alive and running! Here you can see a beautiful waveform of an alpha particle releasing its energy in argon gas at 5 bar of pressure. The large peak at 600 microsecond is the secondary scintillation signal, preceded few tens of microseconds before by the primary one. The small peaks at lower times are believed to be electrons coming from the rubidium source decay, which we have inserted in the gas as a calibration tool.

Stay tuned for the upcoming xenon run!
