A general view of the accelerator is shown here. The main components of the Linear Accelerator (LINAC) are the injector, the accelerator section and the transmission line. The injector made up of an electron gun working at 90 kV, a pre-buncher and a buncher makes it possible to form and pre-accelerated electron pulses. The energy at the exit of the buncher is 3 MeV for ALTO. Electrons leaving the injector will be accelerated up to 50 MeV in the accelerator section. Once the beam has been created, the transmission line will ensure its routing to the target-source assembly under the required focusing conditions. The characterization of the beam throughout the transmission line is ensured thanks to the various diagnostic elements implemented along the line.
