Description
The hosing instability, a significant concern for accelerator applications, poses limitations on achieving high energy gain over long distances. Understanding and mitigating this instability is crucial for advancing accelerator technologies. The AWAKE experiment at CERN offers a unique opportunity to investigate the hosing instability in a plasma wakefield accelerator using a long proton bunch driver. The recent upgrade of the AWAKE plasma source enhances the capability to study the dynamic evolution of this instability. Not only is it possible to study the hosing evolution along the drive bunch, but it is also possible to observe the growth along the plasma. In this contribution, we present the initial findings that delineate the conditions under which hosing occurs, and its impact on beam quality.
