High Current Injector (HCI) is an upcoming accelerator facility at Inter-University Accelerator Centre, New Delhi, India. This comprises of high temperature superconducting Electron Cyclotron Resonance (HTS-ECR) ion source, normal temperature Radio Frequency Quadrupole (RFQ), IH-type Drift Tube Linear (DTL) resonators and low beta superconducting Quarter Wave Resonator (QWR) cavities to accelerate heavy ions having A/q ≤ 6. The compact diagnostic system consists of Faraday cup, slit scanner and capacitive pick up to measure the current, profile, position and bunch length of incident ion beam respectively. It is especially designed and fabricated to measure the beam parameters at the entrance of each of six IH-DTL resonators. The compactness is preferred to minimize the transverse and longitudinal emittance growth at the entrance of DTL resonators. The beam current and profile measurements of various heavy ion beams at different energy have been carried out to validate the design and fabrication of the diagnostic system. Here we are presenting the detailed information about its design, fabrication and various test results.
