The CLIC project is developing a multi-TeV center-
of - mass electron-positron collider based on high gradient,
room-temperature accelerating structures and a novel
two-beam RF power generation scheme. The RF power
for the CLIC accelerating structures is provided by the so-
called drive beam, which is a low energy, high current
electron beam. The drive beam will be generated from a
high current (up to 5 A) pulsed (0.142 ms) thermionic
electron gun and then followed by a bunching system.
The bunching system is composed of three sub-harmonic
bunchers operating at a frequency of 499.75 MHz, a pre-
buncher and a traveling wave buncher both operating at
999.5 MHz. The pre-buncher cavity, which has a great
importance on minimization the satellite population,
should be designed with special consideration of the high
beam loading effect due to the high current beam crossing
the cavity. In this work, we report on RF design,
analytical beam loading calculations and simulations for
the CLIC drive beam injector pre-buncher cavity
