BEAM EXTRACTION SYSTEM AND EXTERNAL BEAM LINE OF KOLKATA SUPERCONDUCTING CYCLOTRON

All the major components of the extraction system of the Kolkata superconducting cyclotron are installed and functional. It includes the Electrostatic deflectors, magnetic channels, M9 slit etc. Internal beam acceleration has already been done successfully and now we are on the verge of extracting and transporting the beam to the cave. The external beam transport system has been designed comprising of quadrupole magnets, steering magnets, switching magnets, beam diagnostics etc. One of the four beam lines has been installed, which extends 20 meters up to the experimental cave-1. Control and monitoring system for all these components have been developed and tested. All the beam dynamical and technical aspects of the beam extraction and beam transportation have been discussed.
