▼a Coherent electron Cooling (CeC) is a sophisticated technique which has the potential to significantly reduce the cooling time in high-energy hadron machines and provide a substantial luminosity boost in high-intensity hadron-hadron and electron-hadron colliders. The CeC Proof of Principle (PoP) accelerator is a unique facility which is currently under commissioning at Brookhaven National Laboratory (BNL). The accelerator utilizes one of the few currently operating superconducting RF (SRF) photoinjectors with a warm cathode, which has demonstrated an exceptional performance over the last few years. In this dissertation we present the main results of the CeC PoP commissioning with an emphasis on the performance of the SRF photoinjector. A thorough investigation and the successful suppression of the phenomenon called multipacting (an undesirable resonant process of an electron avalanche buildup) is discussed in great detail. We present a comprehensive study of the beam dynamics at the initial stages of acceleration with a dedicated effort spent on the comparison of the existing tools for simulations. The outstanding performance of the photoinjector is discussed along with the challenges and corresponding solutions which were met during the commissioning of the CeC PoP accelerator. Special focus will be given to the unexpected experimental results obtained during the last year of operation, and the discovery of a previously unknown type of microwave instability--a micro-bunching Plasma Cascade Instability (PCI). We provide the experimental evidence of the PCI along with the brief theory of the instability. As a conclusion, the possible ways of suppression and future applications of the PCI are outlined. |
