MEBT Research groups

The MEBT is the section of the Accelerator that goes between RFQ and DTL. ESS Bilbao is responsible for the design and fabrication of the ESS MEBT as an In-Kind contribution. In the Medium Energy Beam Transport (MEBT) section the transverse and longitudinal beam characteristics are diagnosed and optimised for further acceleration in the Drift Tube Linac (DTL).

The MEBT operates with a proton beam of 3.6 MeV and currents of 62.5 mA and nominal pulses of 2.8 ms. The MEBT is 3.81 m length for the integration of the different components. The MEBT components are installed on their dedicated vacuum vessels, which are placed over the support rafts.

A set of 11 quadrupoles is used to match the transversal beam characteristics and three RF buncher cavities to fulfil the longitudinal parameters. The beam pulse is shaped using a stripline fast chopper with rise times of less than 10 ns. The beam characterization is done with a complete set of diagnostics: wire scanner , Emittance Meter Unit, Faraday Cup, BPMs, BCMs…).
