Author(s): Walter Hartung, Wei Chang, Yoo-Lim Cheon, Kyle Elliott, Sang-Hoon Kim, Taro Konomi, Patrick Tutt, Yuting Wu, and Ting Xu As large-scale superconducting-cavity accelerator facilities transition from the construction phase to the operational phase, the attention shifts from producing high-performance cryomodules to maintaining cryomodule performance. In situ plasma processing has helped to reduce field emission in superconducting linacs...

Author(s): Adham Naji, Pawan Kumar Gupta, and Gennady Stupakov Highly overmoded iris-line waveguides offer an attractive solution for the efficient transportation of THz pulses over long distances. This paper presents the general (full-scatter) field analysis for the iris-line and its discontinuities under a paraxial excitation by an arbitrary source. By developing an advanced technique that combines Lorentz’s reciprocity theorem (with a generalized...

Craievich Radio-frequency (rf) photo-guns are the most common electron sources used in LINACs for free-electron laser and Compton facilities, as they provide...

Author(s): Laura Nălbaru, Michaela Arnold, and Cătălin M. Ticoş Laser-driven ion beams possess unique features like ultra-short pulses and high particle fluxes that enable the delivery of ultra-high dose rates relevant for biomedical applications such as FLASH radiotherapy. However, their broad energy spectra and large angular divergence remain major barriers to clinical integration. Here, we demonstrate through numerical simulations the feasibility...

Author(s): Nobuyuki Yoshimura, Takeshi Toyama, and Yoshihiro Shobuda This study presents a comprehensive investigation of intra-bunch dynamics in a high-intensity proton synchrotron, where strong space-charge forces and large chromatic phase coexist, through theoretical analysis, simulations, and experiments at the J-PARC Main Ring. Simulations supported by analytic foundations and experimental results, reveal how space charge modifies the decoherence...

Author(s): Ye Yang, Shlomo Caspi, and Lucas Brouwer We present an analytic solution for conical superconducting accelerator magnets and apply it to canted-cosine-theta magnets, which can potentially be used for the interaction region of particle colliders and medical accelerators.

Author(s): Emmanouil Trachanas, Luca Bellan, Gyula Nagy, Antonio Palmieri, Andrea Bignami, Richard Arthur Wilhelm, Francesco Grespan, and Nikolaos Gazis The erosion of Radio-Frequency Quadrupole (RFQ) electrodes due to sputtering under ion irradiation is examined through coupled particle tracking and SDTrimSP (Static-Dynamic Transport of Ions in Matter Sequential-Parallel processing) simulations. Model validation was conducted using quartz crystal...
