Physical Starting of the First and Second Section of Accelerator Linac-800

The report discusses the modernization of the linear electron accelerator MEA (Medium Energy Accelerator). The aim is to develop a set of MEA based free-electron lasers, imposed a number of emission wavelengths from infrared to ultraviolet. In work presents the results of the physical starting of the first accelerating station and status of work on the second accelerating station linear electron accelerator LINAC-800, as well as start the infrared undulator. We discuss the program of work of the accelerator.
