Project summaryThe SPL (Superconducting Proton Linac) project is being proposed at CERN (European Organization for Nuclear Research) as a source of high power proton beam (average beam power 4 MW, energy 2.2 GeV). SPL is developed as a proton driver for a neutrino factory and for a second-generation radioactive beam facility. Realization of the SPL project would make it possible to carry out unique experiments on neutrino physics and nuclear physics.
The SPL project calls for accelerating structures of different types, depending on the energy of particles being accelerated. In the high energy part of the SPL CERN standard superconducting cavities are utilized. But these cavities can not be used for acceleration of low b particles. This is why the front end of the SPL is normal conducting. The SPL front end consists of accelerating structures of different types as well. At the energy > 40 MeV CCDTL (Coupled Cavity Drift Tube Linac) structures are used. These structures are effective up to the energy of 100-120 МэВ. Total length of the CCDTL part is 45 m. This calls for the development of a technology for serial production of the CCDTL structures. Besides, a normal conducting option is still worth investigating in the energy range from 100-120 to 150-180 MeV because at the energy below 150-180 MeV expensive non-standard superconducting cavities would be required.
In terms of this ISTC project we plan to develop the technological basis for serial production of the CCDTL structures in Russia, adapting the CCDTL design to Russian technologies, to produce and test a CCDTL prototype at the design field gradient. Minimization of the serial production cost is an essential consideration for the technology development.
We also plan to study the possibility of application of normal conducting accelerating structures in the energy range up to 150-180 MeV. We plan to make a comparative analysis of electrodynamic characteristics, production complexity and cost of different types of structures; based on this analysis a structure for the SPL will be selected; it will be optimized and a general design will be worked out; models of the structure will be produced and experimentally investigated.
The competence of the participants of this project is based on extensive experience in the activities on similar subjects.
BINP SB RAS is one of the recognized world centers on high energy physics research. The Institute gained an extensive experience in the development, design, production and operation of charged particles accelerators of different types. This ensures that the goals of the project will be succeed by the Institute in collaboration with RFNC-VNIITF.BINP SB RAS has a positive experience of working with ISTC.
RFNC-VNIITF has a long-term experience in the development of unique equipment, simulation of various thermal and electromagnetic field problems. RFNC-VNIITF has advanced production facilities. RFNC-VNIITF has a positive experience of working with ISTC.
CERN is the largest European organization on nuclear physics research. In terms of this project CERN will make an expertise of the results obtained. We plan to hold meetings with Russian scientists and representatives of CERN in order to discuss the work progress and the results obtained. Tests of the CCDTL prototype will be carried out on the CERN test equipment with participation of Russian scientists. Technical documentation will be prepared according to the CERN requirements and standards.
Participation in this project will give scientists from BINP SB RAS and RFNC-VNIITF an opportunity to contribute to the solution of international scientific and technical problems, to exchange information with European colleagues. Weapon scientists and engineers of RFNC-VNIITF will get opportunities to redirect their talents to peaceful activities.
