Electron emission is the first stage of the acceleration and It usually sets the maximum achievable beam brightness and emittance. Therefore, to achieve the highest beam qualities, high-brightness electron sources are in demand. This talk will present research towards attaining electron beams using both Field and Photoemission. The first being ideal in industrial applications due to its laser-free emission process, while the latter is required to generate ultra-bright electron bunches that will guide the future of electron-based accelerators and hadron cooling experiments. Here we present the design and initial tests for a conduction-cooled electron gun. Additionally, we will present the modeling of an integrated photo-injector capable of producing beam parameters required for future X-ray free electron lasers.
