IFMIF, the International Fusion Materials Irradiation Facility, is an accelerator-based neutron source that will use Li(d,xn) reactions to generate a flux of neutrons with a broad peak at 14 MeV equivalent to the conditions of the Deuterium-Tritium reactions in a fusion power plant. IFMIF is conceived for fusion materials testing. [Further reading]. IFMIF/EVEDA project is jointly developed by Europe and Japan. Check here the list of contributing institutes and universities.
LIPAc, the Linear IFMIF Prototype Accelerator, is currently ongoing installation and commissioning in Rokkasho, Japan. Check here the latest status of the commissioning and installation activities.
First injection of RF power into the RFQ
On July 14 it was injected the first power into RFQ. This initial injection was at very low power as the team was extremely cautious in this first crucial moment.
A maximum of 3.5 kW in pulsed mode were injected, obtaining about 70% of reflected power at the input chain and 10% of power in cavity. The other 20% was reflected on the other chains. Results are in perfect agreement with previous simulations from INFN.
In attachment the picture of the scope: yellow signal is the forward power of chain 1 read on RFQ reflectometer, blue signal is the reflected power of the chain 1 read on RFQ reflectometer, violet signal is the power remaining in the RFQ, green signal is the reflected power read on another chain.
It is a first step but results are very important and promising for the coming RFQ conditioning stage.
F4E Director meets with Japanese partners
(Rokkasho, 14 October 2016). At Rokkasho Fusion Institute, in the very north of the Honshū island, Johannes Schwemmer discussed the Broader Approach collaboration and progress with Kenkichi Ushigusa (Director General), Yoshitaka Ikeda and Shigeru O’hira (Vice-Directors). A visit to the laboratory allowed him to see not only the DEMO research activities, but also the supercomputer HELIOS (one of the IFERC projects) and the impressive progress of installation of the Linear IFMIF Prototype Accelerator (LIPAc). Last but not least, this was an opportunity to understand, over a cup of coffee, how F4E employees and other European researchers live and work in Rokkasho.

100mA beam extracted after long maintenance shutdown
After a shutdown period of more than five months long, along which a thorough maintenance campaign on the injector took place, 90keV proton beam, with more than 100mA current, was extracted again this week, in preparation for the last injector commissioning campaign that will span over 5 weeks until November 4th.
Further details, together with details on the progress of installation activities, can be found in the corresponding newsline.
Ceremony held in Rokkasho on 21st April 2016
A ceremony for the celebration of the success of the Injector commissioning and the start of the installation of the RFQ, RF Power generator, MEBT and Diagnostics was held at Rokkasho site with the presence of Japanese and European authorities. (newsline)
Progress in the installation of the RFQ and RF Power of LIPAc
During the last days the activity has been intense. The installation of the RFQ has progressed and it is almost ready for the Bead Pull measurements scheduled next month. Also the third module of the RF power is almost installed. In parallel, D-Plate and MEBT were unpacked and pre-positioned in the vault.
The IFMIF/EVEDA Project Committee #17 in Rokkasho.
Last 13 and 14 March the IFMIF/EVEDA Project Committee took place in Rokkasho. The Committee members could also witness the recent progress of the installation of the RF modules of LIPAc, as well as the latest deliveries from Europe (RFQ supermodules, cooling skids, RF power modules).
The RFQ arrived in Rokkasho.
