Neutralization Circuit of 28 MHz RHIC Amplifier
- Brookhaven National Laboratory (BNL), Upton, NY (United States). Relativistic Heavy Ion Collider (RHIC)
It is desirable to increase the power gain of the 28 MHz RHIC power amplifier in order to reduce the required output of the QEI driver. Since the input power consumption of the 4CX150,000E tube circuit is negligible, the main power drain is the 200 ohm loading resistor in the amplifiers input circuit. The purpose of this resistor is to reduce the likelihood of oscillation due to the negative input impedance introduced by the tube internal feedback capacitance (plate to grid). Neutralization is used to overcome this effect. The neutralization circuit will be examined to see if increasing the input loading resistor is feasible.
