A second phase of the research program is planned to run in\u0000early 2025 and will incorporate an optical amplifier to enable significantly\u0000increased cooling rates and greater operational flexibility. In addition to\u0000beam cooling, an OSC system can be configured to enable advanced control over\u0000the phase space of the beam. An example operational mode could enable\u0000crystallization, where the particles in a bunch are locked into a\u0000self-reinforcing, regular microstructure at the OSC fundamental wavelength; we\u0000refer to this as Optical Stochastic Crystallization (OSX). OSX represents a new\u0000path toward Steady-State Microbunching (SSMB), which may enable light sources\u0000combining the high brightness of a free-electron laser with the high repetition\u0000rate of a storage ring. Such a source has applications from the terahertz to\u0000the extreme ultraviolet (EUV), including high-power EUV generation for\u0000semiconductor lithography.

Our previous research\u0000highlighted that filling patterns have a substantial impact on BBU\u0000instabilities in multi-pass ERLs. In this study, we extend our investigation to\u0000the 8-cavity model of the Powerful ERL for Experiment (PERLE). We evaluate its\u0000requirements for damping cavity Higher Order Modes (HOMs) and propose optimal\u0000filling patterns and bunch timing strategies. Our findings reveal a significant\u0000new insight: while filling patterns are crucial, the timing of bunches also\u0000plays a critical role in mitigating HOM beam loading and BBU instability. This\u0000previously underestimated factor is essential for effective BBU control. We\u0000estimated the PERLE threshold current using both analytical and numerical\u0000models, incorporating the designed PERLE HOM dampers. During manufacturing, HOM\u0000frequencies are expected to vary slightly, with an assumed RMS frequency jitter\u0000of 0.001 between cavities for the same HOM. Introducing this jitter into our\u0000models, we found that the dampers effectively suppressed BBU instability,\u0000achieving a threshold current an order of magnitude higher than the design\u0000requirement. Our results offer new insights into ERL BBU beam dynamics and have\u0000important implications for the design of future ERLs.","PeriodicalId":501318,"journal":{"name":"arXiv - PHYS - Accelerator Physics","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
