Abstract :
Damping of parasitic oscillations, preventing high frequency tube failures and an alternative tube allow now to offer two solutions for at least 1.3 MW with the existing final amplifier for the 108 MHz Unilac Alvarez structure. This peak power, delivered with 25 % duty cycle at 50 Hz, satisfies all requirements of the Unilac operation, even for acceleration of gas stripped Uranium ions.
