They provide good stability at sufficient speed-work. 2.Increased requirements of technological lines to the speed of the accelerator injection to set-up parameters and introduction of technological lines, in which the accelerator is a slave device and should within the shortest possible time to respond onto the changes of operation input parameters, forced us to find the way of stabilization systems improvement. 3.New stabilization system is able to provide current output speed up to 5mA/sec, at required energy stability. 4.Digital-to-analog stabilization is produced as a superstructure on the existing system and is made as a source code added into the basic accelerator control program. This approach enables to modernize simply the existing accelerators. The code itself is two independent parts. The first part is the current beam corrector, which calculate the derivate (current speed) at a time and aims to hold it in set-up range, taking into account the difference of the tasks and the necessity of cathode warm up. The second part is a energy compensator. It adds the current derivate into accelerator energy channel, reducing the energy settlements at once. 5.Present system passed through the testing and it is already installed onto ELV-0.5(0.5MeV, 100mA) accelerator in Qingzhou (a/m tyre production) and onto ELV-8(2.5MeV, 40mA) accelerators in China for cable insulation treatment.
