We systematically optimize the yield of XUV pulses at 93 2 eV with respect to
experimentally adjustable parameters such as gas pressure, focal position of laser
beam and interaction length by using few cycle laser pulses. We demonstrate
carrier-envelope phase dependence of the optimized XUV spectrum, consistent
with the formation of isolated attosecond pulses. We present the progress to-
wards a newly developed attosecond beamline and describe its essential parts in
detail. We perform initial experiments on photoelectrons detection. This work
will contribute further for optimizing the setup for attosecond streaking experiments.We systematically optimize the yield of XUV pulses at 93 2 eV with respect to
