5th Slow Extraction Workshop at MedAustron in Wiener Neustadt

This presentation describes some of the beam losses and instabilities observed in the MedAustron synchrotron during operation that could potentially affect the efficiency of RFKO slow extraction. The slow extraction process at MedAustron is driven by a Betatron core for clinical operation, and the RFKO method is being studied experimentally in view of a future machine improvement. This study...

The NASA Space Radiation Laboratory (NSRL) uses beams of various ions species slowly extracted from Booster synchrotron at Brookhaven National Laboratory. Experimenters at NSRL require uniformly distributed radiation dose to simulate the space radiation environment. The NSRL facility generates uniform beam distribution of various ion species at the location of the target using a pair of...

The SESRI facility, known as the Space Environment Simulation and Research Infrastructure, was successfully completed in Harbin, China, in 2022. It stands as a comprehensive ion species facility exclusively dedicated to space environment simulation and associated scientific research.
During the design and construction phases of SESRI, two major challenges were encountered. To effectively...

The synchrotron SIS100 has been optimized for operation with the partially
stripped ion U28+, resulting in a number of unique challenges: transverse
emittances are comparatively large; the beam has high damage potential due to
the high dE/dx; the lattice must provide efficient collimation of ions losing
electrons in collisions with residual gas to prevent vacuum instabilities.
Resulting...

Modern low emittance lattices typically require a reduced cell length and high quadrupole gradients, thereby generating large natural chromaticities. Thanks to the low dispersion requirement the chromaticity correction requires strong sextupoles, which accentuate the role of the non-linear dynamics in the machine. We present the design considerations of a resonant slow extraction based on the...
