Achieving strong focusing of MeV electron beams is a critical requirement for advanced beam applications such as ultrafast electron diffraction (UED). To address this, a novel permanent magnetic solenoid (PMS) has been designed, fabricated, and tested. The solenoids provide a compact and efficient solution for delivering high magnetic fields to focus short, low-emittance electron bunches....
RF breakdown studies are crucial for machines relying on high-gradient, normal-conducting RF accelerating cavities. Searches for breakdown precursors in high-gradient test-stand data have been conducted and highlight the need for a new diagnostic with improved temporal response. Emission of Cherenkov light in optical fibers has been identified as one such diagnostic**, which occurs when...
