The paper presents the electron injector for the linear accelerator of TNK facility (Zelenograd). The injector has rather simple design because of realized injection scheme with no prebunching. The beam is divided into bunches directly by the accelerating RF field of the linear accelerator. The injector block diagram is presented, the process of electron beam bunching and acceleration is described.

TNK facility (F.V. Lukin Institute, Zelenograd) was designed and manufactured at Budker INP. It includes 80 MeV electron linear accelerator-injector and two electron storage rings: the main ring for energy of 2.5 GeV and booster ring for energy of 450 MeV. The paper presents the functional layout of the linear accelerator. The disk-and-washer 2.8 GHz accelerating structure is described. Results of the accelerator startup is presented. In December 2005, accelerated electron current of ~50 mA with energy of ~50-60 MeV was obtained; the beam was captured into the booster ring.
