Present Status of IFMIF Prototype Accelerator

Abstract

The development of linear IFMIF prototype accelerator is underway with international collaboration between EU and Japan. The RFQ was installed in 2016 and first hydrogen beam was accelerated in July 2018. The beam current was increased up to the nominal value (~60 mA), and the first D-beam acceleration was done in March 2019. At present, the D beam experiment is continued aiming 125 mA at 5 MeV using a beam dump for short pulse mode (1 ms pulse, 0.1% duty cycle). In parallel, the assembling of the SRF linac which will be installed at the downstream of the RFQ linac is underway. The CW beam dump was already installed. The activities for CW operation will be started in 2020.
