32. Bunch-by-bunch feedback system for hybrid filling and recent topics in SPring-8

The hybrid filling composed of singlets with high bunch current and bunch trains with low bunch current is in user operation at SPring-8, by simultaneously suppressing single-bunch instabilities of singlet and multi-bunch instabilities of trains by the Spring-8 bunch-by-bunch feedback system. To overcome the high contrast of the bunch current between singlets and trains, a bunch current...

33. Far-infrared and Terahertz detectors for particle accelerators

Different radiative phenomena in the far infrared and terahertz ranges can occur in particle accelerators. Smith-Purcell radiation is emitted when a charged particle passes near a grating. It is being used by the ETALON group at LAL Orsay to determine longitudinal profiles of electron bunches on different Linacs (FACET at SLAC, SOLEIL). Some results will be presented, showing the feasibility...
