| Popis: | The family of four weak quadrupoles was replaced at VEPP-2000 electron-positron collider with new one. New quads with increased bore diameter made with higher field quality and equipped with fiducial points are excited by water-cooled coils fed with new 300 A power supplies. That allowed to double integrated gradient and to implement so called "warm" operation mode (with switched-off final focus solenoids) above 500 MeV energy level. Presented in the paper "warm" modes are used for beam scrubbing and for resonance depolarization technique of Compton backscattering beam energy measurement system cross-calibration.
