Abstract
Following LIL single beamline commissioning in 2003,
where performance in terms of power and energy required for LMJ was
demonstrated, we spent year 2004 to qualify the quadruplet (or quad)
performance at 1
/3. Over that year, the first quad high
power and high energy laser experiments took place on LIL facility. A
careful set of test campaigns were conducted to safely ramp up laser
performance. The main goal was to measure quad-specific features such as
beam synchronization and focal spot (size, smoothing contrast ratio or
irradiation nonuniformity
versus the LMJ requirements.
LIL Quad beam waist was recorded for various pulse durations, smoothing
techniques and for a wide range of laser intensities up to LMJ-nominal ones.
Now, LIL quad has been commissioned to the center of the target chamber and
the first plasma experiments are made.
