    Disclaimer This document describes the status of the LMJ-PETAL facility and provides the necessary technical

    references to researchers intending to perform experiments on LMJ-PETAL. Some devices presented in this document are under development; the data given here, concerning their

    characteristics, correspond to the specifications. Some small differences could exist between the specification and the realization.

    All the presented devices should be available at the beginning of 2019, but some delays are possible. The performance obtained by the facility so far, and reported in this document, do not commit the

    future performance.
