Design and Development of 3.2m Radio Frequency Quadruple LINAC

The high energy Radioactive Ion Beam (RIB) play an important role in R&D in the field of Nuclear Physics, Nuclear Astrophysics, Material Science, Biology and Medical Science. The technology needed for developing RIB facility is extremely complex and it requires extensive R&D in the field of particle accelerators, ion sources, instrumentation and manufacturing technology. To carry out this challenging task Variable Energy Cyclotron Center (VECC, Department of Atomic Energy) has signed an MOU with Central Mechanical Engineering Research Institute (CSIR-CMERI), Durgapur, for collaborative work in system design and development  of Radioactive Ion Beam (RIB)  facility at VECC Kolkata.

The conceptual and system design from accelerator physics and beam dynamics principles has been done by Variable Energy Cyclotron Center(VECC). CSIR - CMERI Durgapur and VECC Kolkata have worked collaboratively for Engineering design, System Analysis for the development of Radio Frequency Quadrupole (RFQ) Linac along with Electron Cyclotron Resonator (ECR) as its ion source and Beam Rebuncher ( Linac-RB)   for rebunching its medium energy output ion beam.

Project Type:
Project Date:

The first half scale 2kW prototype with vane length 1.7m (input energy 1.68Kev/u and output energy 29.5 Kev/u) was designed, developed and tested in Sept 2005 for optimizing the design parameters. After studying its performance the final 40kW RFQ Linac with 3.2m vane length (input energy 1.68Kev/u and output energy 97.5 Kev/u)  was designed, developed and tested in 2008 with design modifications. It is  2nd in Asia after Japan. Very few countries in the world have this capability. After achieving this feat India joined the club  of  USA, Canada, France, Germany, Israel, Japan and Russia for indigenous  development of  this  highly guarded technology, as an output of collaborative research between VECC(DAE) and CSIR-CMERI.
