A high performance electron cyclotron resonance ion source (ECRIS) called PKDELIS capable of operation at 14.5 and 18 GHz and which uses High Temperature Superconducting (HTS) coils designed jointly by IUAC, Delhi (earlier called NSC), Pantechnik, Caen and ISN, Grenoble is presently in operation. The source is very suitable for operation on a 400 kV high voltage platform for injecting beams from the High Current Injector (HCI) into the Superconducting Linear Accelerator Booster. In the low energy beam transport (LEBT) system of the HCI, the beam extraction and transport becomes more and more challenging. In order to avoid the losses of the beam, the complete transport system is being made as short as possible. In addition, due to the high currents (~10 mA) extracted, the extraction system needs proper cooling requirements and possibility of movement of the electrodes for tuning various A/q beams. Typical axial and radial bremstraahlung spectra have been measured from the ECR plasma. Details will be discussed and further measurements are being explored to obtain a better understanding.
