Planning and development an data warehouse ETL (Extraction, Transformation and Load) system, is typically a complex and time consuming task whose complexity is highly influenced not only by the amount of data to analyze, but also the computational effort required to integrate these data in same data structure and storage model in order to load it into a final data repository. Despite its enormous...
Beam interaction with background gas and walls produces ubiquitous clouds of stray electrons that frequently limit the performance of particle accelerator and storage rings. Counterintuitively we obtained the electron cloud accumulation by measuring the expelled ions that are originated from the beam-background gas interaction, rather than by measuring electrons that reach the walls. The kinetic ion...
