SPIRAL2 RFQ bunch lengths and longitudinal emittance measurements

摘要

The SPIRAL2 beam commissioning has started and the superconducting linac installation is being finalized. The conditioning of the Radio Frequency Quadrupole (RFQ) [1] begun in 2015, and the beam commissioning soon after. Among the beam parameters checked at the RFQ output, the energy, bunch length and longitudinal emittance have been measured for the 3 referenced particles.
