The High Current Injector (HCI) was designed and built as a dedicated single turn injector for the Test Storage Ring in Heidelberg to deliver mainly very high intensities of singly charged Li- and Be-ions for laser cooling experiments. After start of routine operation in 1999 the HCI delivered high quality beams for about 25% of the experiments with very high reliability. Due to the experimental requirements the HCI mutated from a specialized injector to a versatile multipurpose instrument, able to deliver a large variety of atomic and molecular light ions with either positive or negative charge. In addition provisions are far advanced to implement a custom built 18 GHz high power ECR-source for the injection of highly charged heavy ions suitable for further acceleration. This paper gives an overview of the experience gained so far and presents the status of the upgrade of the HCI.
