Status of Linacs with High-frequency Quadrupole Focusing LU-30 and LU-30M in IHEP

IHEP, Moscow Region, Russia

There are two RFQ DT proton linacs, named the LU-30 and LU-30M, in the SRC IHEP of NRC "Kurchatov Institute" that are presently in operation. Both are the unique machines employing radio-frequency quadrupole focusing up to 30 MeV at exit. The LU-30 machine now runs as a proton injector to the booster RC PS U-1.5 that feeds the main PS U-70 ultimately. The LU-30M is now run in a stand-alone test operation mode. Such a parallel functioning of these two accelerators allows to use the LU-30M as an experimental facility enabling R&D on new technical decisions and upgrades for the ageing LU-30. On the other hand, the routine operation of the workhorse LU-30 allows for testing of the technical decisions proposed under a heavy non-stop operation during the U-70 runs for fixed-target physics.

Alternative nuclear energetic's technologies as fast reactors and accelerating driven systems (ADS) are necessary to solve a number of problems as U-238 or thorium fuel reactor and nuclear wastes transmutation. ADS subcritical system should consist of megawatt-power proton accelerator, neutron producing target and breeder. A number of ADS projects are under development in EU, Japan, USA, China, S.Korea at present. Superconducting linacs or their complexes with high energy storage synchrotron are under design in main projects as a megawatt power proton beam driver. In Russian Federation the complex design for accelerator-driver was carried down more than ten years ago. The new approach to the ADS complex is now under development in framework of the project carried out by collaboration between Russian scientific centers MEPhI, ITEP, Kurchatov Institute. This project was supported in 2013 by the Ministry of Science and Education of Russia. A brief results observation for accelerator part of the project is presented in report. It includes accelerator-driver general layout, beam dynamics simulation, electrodynamics simulations of accelerating cavities and analysis of technological background in Russia.

To date, Warsaw U200P cyclotron exploited a mirror inflector to feed heavy ions extracted from ECR ion source (10 GHz, 11 kV) to the central region of the cyclotron. However, in such configuration very low transmission was reachable after many optimizations. Additionally, the new ECR ion source (14,5 GHz, 14-24 kV) was installed, which offers energies far exceeding capabilities of the currently operated inflector and central region. To avoid these obstacles, we have developed a spiral inflector and redesigned central region of the cyclotron. It was a very challenging task, bearing in mind limited volume of central region in our compact machine, to carve these elements suitably for decent versatility of ion beams offered by Warsaw cyclotron. This project was executed in the collaboration with FLNR in Dubna, Russia. The cyclotron equipped with the new central region works in the "constant orbit" regime. Here we present the results of both computational simulations and measurements of the beam transmission in upgraded central region.
