	The CAPRICE ECRIS installed at the High Charge Injector (HLI) of GSI produces highly charged ion beams from gaseous and metallic elements. A high demand of metal ions comes from the nuclear physics, material re-search, and Super Heavy Element group (SHE), and the most requested element, besides 50Ti, is 48Ca. When this chemical reactive material is deposited inside the plasma chamber at internal components the stability can be com-promised. Furthermore, it is difficult to find a working point to guarantee a long-term stability as the oven re-sponse time and the reaction of the ECRIS are relatively slow. The monitoring by using an Optical Emission Spectrometer (OES) facilitates immediate reactions when-ever plasma instabilities occur. For this reason, a real-time diagnostic system based on an OES has been in-stalled at the ECRIS at HLI for routine operation during the beam-time 2020. The measured spectra revealed a parasitic oven heating by coupled microwaves often com-promising the ion source performance. Therefore, a tung-sten grid has been installed to shield the oven orifice from the coupled microwaves. The results in terms of 48Ca beam intensity and stability are reported here.

The CAPRICE ECRIS installed at the High Charge Injector (HLI) of GSI produces highly charged ion beams from gaseous and metallic elements. A high demand of metal ions comes from the nuclear physics, material re-search, and Super Heavy Element group (SHE), and the most requested element, besides 50Ti, is 48Ca. When this chemical reactive material is deposited inside the plasma chamber at internal components the stability can be com-promised. Furthermore, it is difficult to find a working point to guarantee a long-term stability as the oven re-sponse time and the reaction of the ECRIS are relatively slow. The monitoring by using an Optical Emission Spectrometer (OES) facilitates immediate reactions when-ever plasma instabilities occur. For this reason, a real-time diagnostic system based on an OES has been in-stalled at the ECRIS at HLI for routine operation during the beam-time 2020. The measured spectra revealed a parasitic oven heating by coupled microwaves often com-promising the ion source performance. Therefore, a tung-sten grid has been installed to shield the oven orifice from the coupled microwaves. The results in terms of 48Ca beam intensity and stability are reported here.
