with a deliberate pre-pulse on solid targets using the Vulcan Petawatt Laser facility. The measurement of the number and temperature of hot electrons obtained using an electron spectrometer. The results are correlated to the density scale length of the plasma produced by a controlled pre-pulse measured using an optical probe diagnostic. The experimental results show that longer interaction plasmas produced by pre-pulses enable significantly greater number of hot electrons to be produced.

被引用回数：39 パーセンタイル：82.89(Physics, Fluids & Plasmas)X-ray emission from hollow ions offers new diagnostic opportunities for dense, strongly coupled plasma. We present extended modeling of the X-ray emission spectrum obtained in relativistic laser plasma based on two collisional-radiative codes: the hybrid-structure SCRAM model and the mixed-unresolved transitional arrays (UTA) ATOMIC model.
