20081030Di-STF1m.jpg

During a pulsed RF operation of TESLA-like cavities in a horizontal cryostat at STF, the cavity #2 recorded an accelerating field of 30.1MV for 1.5ms pulses at 5Hz on 2008/10/30. The picture above shows the scope traces during the measurement. Blue: Input power; Light blue: Input phase; Green: Relative phase of transmitted power; Magenta: Accelerating field. RF feedback is turned on, while piezo compensation is not yet activiated.
