Experimental hall

The experimental hall houses all the vacuum equipment and plasma diagnostic equipment surrounding the experimental chamber.

The beams end their journey in the experimental hall, where they are focused on the target located at the center of the experimental chamber.

Experimental chamber

Located at the center of the experimental hall, the LMJ’s experimental chamber is a 10 m sphere weighing around 140 metric tons. It has a 10 cm aluminum wall that is covered by a 40 cm layer of borated concrete that forms a biological shield to protect staff and equipment during fusion experiments. It has been assembled and precision welded on the construction site of the Megajoule Laser.

The LMJ experimental chamber was inserted into the LMJ building placed on its pedestal in the middle of the experimental hall in November 2006 Experimental chamber

RIGHT - Under vacuum (one billionth of atmospheric pressure), the experimental chamber will house the target and hold many diagnostic instruments, enabling plasma characteristics to be measured during the experiments (light spectra, neutrons, temperatures, densities, etc.). © CEA
