15:50 - Beam injected in the ring. Taking data for longitudinal tomography with a linear ramp and with flattop. Scope sample rate increased to a step size of 4ns (it was normally 40ns) to ensure a sufficient number of points for the reconstruction.
Data taken for tomography study.
Data with RF start refers to the time window on the scope including the start of the RF waveform which occurs before the beam is injected.
