The HITRAP facility is designed to decelerate and cool a bunch of about 10
We present the current status of the HITRAP cooling trap and the next steps of commissioning this setup with offline ions. Recently, a new electrode layout has been installed to improve reliability of the trap operation. Our tests show that the new seven-electrode design is more stable and less error prone than the old 21 electrode design.
We were able to investigate the storage of argon ions in various charge states, delivered by a small EBIT with an energy of 4
The next steps will be the improvement of the trap settings for the simultaneous storage of electrons and ions and the proof of electron cooling of argon ions from the local ion source. Additionally, methods for non-destructive detection of trapped particles will be applied to the setup.
This work is supported by BMBF under contract number 05P21RDFA1.
