Abstract: | Compression and pinch phase at the plasma focus were investigated by streak camera observations of the visible emission. The duration of maximum local compression provides no evidence for magnetic confinement of the focus plasma. With increasing hard X-ray intensity a decreasing of the temporal evoution of the pinch phase is observed, indicating enhanced diffusion of magnetic field energy into the locally compressed plasma. |
