Abstract

We present preliminary experiments and calculations performed to optimize the photoionization of an He-like aluminum plasma. The high emissivity of the 3d-4f M-band of tantalum or tungsten is used as the pump. The plasmas are produced by two 500 ps duration beams of a frequency doubled Nd-glass laser. The pump beam is delayed by 1 ns with respect to the main beam. The Al plasma ionization state has been measured with K-alpha absorption measurements. X-ray diodes and space-resolving crystal spectrographs have been used to measure the intensity of the pump source in the desired spectral range. Optimization of the pumping scheme is analyzed with a numerical description of the photopumping process by a collisional-radiative modeling of the Al plasma including the X-ray pump.
