	A perpendicular biased 2nd harmonic cavity is being designed and built for the Fermilab Booster. Its purpose is to flatten the bucket at injection and thus change the longitudinal beam distribution to decrease space charge effects. It can also help with transition crossing. The cavity frequency range is 76 - 10⁶ MHz. It is modeled using CST microwave studio and COMSOL. The power amplifier will use the same tetrode as is used for the fundamental mode cavities in the Fermilab Booster (Y567B). We discuss recent progress on the cavity design, plans for testing the tuner's garnet material, and tests of the power source.
