Superconducting Linacs Development for Current and Future Russian Accelerator Projects: Progress and Problems | |
|
||
|
Superconducting linac is nowadays a standard technology to generate high-energy proton and ion beams especially for CW operation mode. Starting from SNS at ORNL * superconducting radio frequency (SRF) technology and superconducting (SC) linacs are changed from the exotic to classical technology of today. Many ion accelerator complexes developed in USA, EU, Japan, China, Korea and other countries for spallation neutron sources, production of radioactive ion beams and ADS (Accelerator Driven System) drivers use SC cavities. Currently, the mega-science accelerator project NICA ** (Nuclotron-based Ion Collider fAcility, JINr) as well as new proposed projects DERICA *** (Dubna Electron-Radioactive Ion Collider fAcility), NEPTUN, BELA ****(Based on ECR and Linear Accelerator multidisciplinary facility), etc. cannot be constructed without SRF technologies development in Russia. New ambitious program of SRF technology has been started few years ago by JINR in collaboration with MEPhI, NRC KI ITEP, BSU, PTI NANB, TRIUMF and GSI. Current progress in general conceptual design of new SC linacs, beam dynamics simulation of SC cavities and related issues will be discussed in this presentation.

Beam Dynamics Simulation for LINAC-100 - Heavy Ion "Driver" for DERICA Project | |
|
||
| R&D on new Dubna Electron Radioactive Ion Collider fAcility (DERICA) implies the development of two heavy ion linear accelerators LINAC-100 and LINAC-30 each capable of accelerating ions within the wide range of mass/charge ratios A/Z. LINAC-100 will accelerate intensive CW primary stable isotope beams (from B11 to U238 with A/Z ~6) with beam currents up to 10 puA for radioactive isotope production using fragmentation method. As a concept for LINAC-100 modular system of independently phased SC cavities with NC CW RFQ section in injector part is proposed. In order to obtain maximum range of secondary ions acceleration up to 50 AMeV for U238 and 100 AMeV for "light" ions should be provided. Moreover, to enlarge flexibility in radioactive ion production conditions and expand using of LINAC-100 on applied physics purposes it is desirable to have three modes of accelerator operation: with maximum light ion energies of 50, 75 and 100 AMeV. In this paper the results of A/Z ~6 beam dynamics studies for modular part of LINAC-100 for CW operation mode will be presented. | ||
