Numerical simulation of the performance of the laser facility and automated control of the laser setup process are crucial to the project's success. The virtual model is considered as a set of services and tools that enable transparent execution of computational software for modelling beam dynamics in particle accelerators on distributed computing resources. For laser facilities, these functions can be performed by two closely coupled computer codes: the virtual beam line (VBL) and the laser operations performance model (LPOM).
Different types of diagnostics will be used to calculate the laser intensity on the target. There will be laser beam diagnostics at the output of the lasers and at the end of the beam transport sections, and some other diagnostics inside the beam transport for operating and driving the facility.
