A superconducting reentrant cavity for low beta, high intensity beam has been designed using SUPERFISH and MAFIA. The study has been done for cavity shape optimization considering the minimization of surface fields. Further its structural design has been done and feasibility study of different manufacturing aspects has also been done. A full-scale mild steel model with copper coating has been fabricated. A twin arm mechanical tuner has been designed for slow tuning by elastic deformation. This was tested with low power RF to validate the design parameters and to check the tuning sensitivity. In this paper the design and development activity of the reentrant superconducting will be discussed

Raja Ramanna Centre for Advanced Technology has successfully completed the supply of nearly 2000 nos. Superconducting Corrector (SC) Magnets for the LHC project at CERN. Initial prototypes were developed at RRCAT in collaboration with CERN and large scale production was done in industry. These corrector magnets require precision components, accurate assembly procedure, elaborate testing and stringent quality control required for repeatable performance. A number of sub technologies were developed for these magnets at RRCAT and successfully transferred to Industry. These include precision coil winding, joining SC wire to get low contact resistance, measuring it at 4.2 K. Ultrasonic welding machine and automatic coil winding machines were developed. Cryogenic testing procedures and test facility were established at RRCAT. SC switches and current leads were designed and fabricated. Cryogenic testing at 4.2 K and magnetic measurement at 300 K for all the 2000 magnets were done at RRCAT. Special tooling and inspection gauges for in process inspection were made. In this paper we describe the experience gained during technology development, prototyping and technology transfer to industry.

After signing a Protocol on 29 March 1996 to the 1991 cooperation agreement with CERN, Switzerland, India is participating in the construction of CERN’s most challenging and ambitious particle accelerator the “Large Hadron Collider” (LHC). The contributions span from hardware, software, and skilled manpower support for evaluation of some of the LHC sub-systems and presently to the support in commissioning of various subsystems of LHC. With major achievements on Indian part during the course of time CERN has now invited India to jointly participate further to build CERN’s Advanced Accelerator Projects like Super conducting Proton LINAC, SPL and Compact Linear Collider Test Facility, CTF-3. The present paper describes the achievements to date and high lights the ongoing and future collaboration activities.
