This paper presents the status of powerful linear electron accelerator BETA-8 development. The accelerator is operating in CW mode and used for ionizing radiation research. The basic constituent of accelerator is coaxial half-wave resonator excited on T1 wave. Required electron beam energy is attained by multiple passing through central transversal plane of resonator. Electron beam iterative passing is realized by turning magnets located on resonator outwalls. The main parameters of the accelerator are: beam output energy 1.5 - 7.5 MeV, average power up to 300 kW, operating frequency 100 MHz. By now the main components of facility, namely, coaxial resonator, three HF generator units each with output power 180 kW, HF power summation device, the unit of power input (UPI) designed to transfer HF signal of 600 kW have been designed and manufactured. Electron beam transport system project consisting of up to five full sequential passes through accelerating resonator has been developed. Turning electromagnets have been designed and manufactured. HF parameters measurements for coaxial resonator assembled with UPI have been realized at low HF power level. All HF generator units and HF power summation devices have been tested. HF electron injector has been designed, manufactured and tested. The accelerator testing is supposed to be carried out in one HF generator unit supply mode.
