Abstract :
Summary form only given. The SABRE accelerator was originally designed to operate as low impedance voltage adder with 40-ohm maximum output impedance in negative polarity operation and approximately 20 ohms in positive polarity. Because of the low impedance and higher that expected energy losses in the pulse forming network, the operating input cavity voltage is of the order of 800 kV which limits the total output voltage to /spl sim/8 MV for negative polarity and 5 to 6 MV for positive polarity. The modifications presented here aim to increase the output voltage in both polarities. A new high impedance central electrode was designed capable of operating both in negative and positive polarities, and the number of pulse forming lines feeding the ten inductively isolated cavities was reduced to half.
