The Laser Integration Line (LIL) was first designed as a prototype to validate the concepts and the laser architecture of
the Laser MegaJoule (LMJ). The LIL facility is a 4-beam laser representing a quad structure of the LMJ. A 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. Following the laser commissioning, the LIL has become a major instrument dedicated to the achievement
of plasma physics experiments for the French Simulation Program and was also opened to the academic scientific
community. One of the attributes of the LIL facility is to be very flexible to accommodate the requests of plasma
physicists during campaigns. The LIL is constantly evolving to best meet the needs of target physicists. Changes made or
planned are either to improve the quality of laser beams, or to increase the LIL Energy-Power operating space. To
optimize preparation and design of shot campaigns, the LIL performance status has been elaborated. It gives information
about the characteristics of the laser in terms of near field and far field, defines the steps to maintain performance,
explains how the facility responds to the request, details settings (smoothing, shaping of the focal spot, energy, temporal
pulse shaping, beam pointing) and gives the limits in energy and power. In this paper, an overview of the LIL
performance is presented.
