The high temperature superconducting electron cyclotron resonance ion source (HTS-ECRIS), PKDELIS is in operation since June, 2004. The cryo-coolers have completed about 25000 hours of operation. There were some initial problems with one of the two cryo-coolers for the axial HTS coils, beam extraction and transmission systems at the intermediate location for test run. These were rectified subsequently. Proper X-ray shielding for safe operation were incorporated. X-ray Bremstrahlung measurements on the injection and extraction as a function of negative DC bias voltage are carried out systematically to develop deeper understanding of the ECR plasma production processes. A soft-landing system is developed for studies in charge exchange collisions and potential sputtering. The source and low energy beam transport (LEBT) system is planned to be re-installed on a high voltage platform in the new beam hall III to prepare for injection into high current injector of the superconducting linear accelerator. Recent results of the PKDELIS, operational experience and details of LEBT will be reported.
