Summary: | The first High Temperature Superconducting Electron Cyclotron Resonance Ion Source (HTS-ECRIS) called PKDELIS has been developed as a collaborative project. The source has been designed for suitable use on a high voltage platform with minimum requirements of electrical power and water cooling. The design is based on the required A/q of ~ 7 for the High Current Injector (HCI) of the Superconducting Linear Accelerator (SC-LINAC) at Nuclear Science Centre and to provide relatively higher beam currents of multiply charged ions. High Temperature Superconducting coils (Bi-2223) have been chosen to reduce the power and cooling requirements for obtaining large axial magnetic fields corresponding to a frequency of 18 GHz. The HTS coils are operated in a superconducting mode in a temperature range of about 20 to 22 K using Gifford-McMahon type cryo-refrigerators. A 36 element hexapole was designed using NdFeB to obtain higher fields at the chamber wall. The source is tested thoroughly by producing beams of carbon, oxygen, neon, argon, xenon, tantalum and lead at various charge states having analysed current up to 2 mA. The detailed design aspects and test results are presented. |
