Laser Integration Line
The Laser Integration Line (LIL) is a prototype of an LMJ laser line. Between its commissioning in 2002 and its closure in early 2014, the LIL was the most powerful laser in Europe in terms of delivered energy. The LIL was used to validate technological choices made for the LMJ (before construction of entire LMJ was started and completed) and set up experiments (targets, measurement systems, etc.). It was the site of many physics experiments for defense and academic applications.
The LIL primarily consists of :
After 12 years of operation, 1,595 laser pulses generated on targets and 636 experiments conducted on targets, the last experiments at the LIL were conducted in February 2014.
Its performance (laser-beam quality, experimental data, rapidity of progression of experimental sequences, etc.) was improved throughout its operating life.
The results yielded by the LIL were central in demonstrating the contribution of laser experiments to the Simulation Program. Some of these experiments will be reproduced on the LMJ to address the operation of weapons.
February 2014 : final campaign
The final campaign was conducted for the benefit of the academic teams of the Laser and Plasma Institute (LULI, Ecole Polytechnique and CELIA at the University of Bordeaux). It was conducted as part of a study on an alternative method of inertial confinement fusion whereby deuterium-tritium is ignited by generating a strong shock in the compressed target.
