Fig. 1. Top: Pinhole image. Bottom: Time integrated spectra of plasma of Mo XP_633.
Fig. 2. Close-up of the electrical and photonic records 400 ns around the time of pinching (shot XP_633). The electrical records (voltage, B -dot probe signal, current as numerically integrated from B -dot). X-ray signal is figured out by the XRD signal in volts (right scale).
