We present the first results on the deceleration of SrF molecules in a traveling wave Stark decelerator. Traditional Stark decelerators suffer from overfocusing, leading to losses. This makes it very inefficient to use such a device for the deceleration of heavy diatomics, such as SrF. A long traveling wave decelerator, which is inherently stable, is therefore built in our lab. Using arbitrary waveform generators and high voltage amplifiers we can create true 3D moving electric traps inside the decelerator. After deceleration, we will laser cool the molecules to prepare them for a parity violation measurement. We report the status of the experiment and the possibilities of using different waveforms to optimize the deceleration process.
