MOP021 | Towards the Development of Rare Isotope Beam Facility at VECC Kolkata | 106 |
|
||
An ISOL type Rare Isotope Beam (RIB) Facility is being developed at VECC, Kolkata around the existing K=130 room temperature cyclotron. The possibility of using the photo-fission production route using a 50 MeV electron linac is also being explored. The production target and a 6.4 GHz ECR based charge-breeder system will lead to two beam lines. The first one, a low energy beam transport (LEBT) line consisting of a 1.7 m long, 33.7 MHz RFQ, will be dedicated to material science & other ion-beam based experiments. The second, post-acceleration beam line will accelerate the beams to 1.3 MeV/u using a longer, 3.4 m RFQ and a series of IH linear accelerators. In the first stage, the beam energy will be about 400 keV/u using three modules of linacs. Subsequently the energy will be boosted to about 1.3 MeV/u. Some of the systems have already been installed and made operational. The LEBT line has been tested and stable ion beams accelerated to 29 keV/u with high efficiency in the 1.7 m RFQ. The 3.4 m RFQ and the first IH Linac tank are under installation in the post-acceleration beam line. In this contribution an overview of the present status of the facility will be presented. |

Radio Frequency Quadrupole (RFQ) would be the first post accelerator for the upcoming Rare Isotope Beam (RIB) facility at Variable Energy Cyclotron Centre (VECC), India. A 33.7 Mhz RFQ capable of accelerating stable as well as RI beams of q/A > 1/16 to about 30 keV/u has already been constructed and operational since September 2005 . This has been installed in a dedicated beam line for doing material science experiments. Another 3.4 m long RFQ resonating at 37.6 Mhz and capable of accelerating heavy ion beams up to 98 keV/u have been fabricated which is to be installed in the beam line for the VEC-RIB facility. The physical parameters,rf test along with the measurements of accelerated beams from RFQ would be presented. |
