Exciting News!

We're thrilled to announce that our latest preprint is now available on arXiv!

📄 Title: 3D-printed components for electron-ion trapping: Tests of functionality and ultra-high vacuum compatibility

🔗 Read the full abstract here: https://arxiv.org/abs/2509.06537

In this work, we demonstrate the ultra-high vacuum (UHV) compatibility of a microwave-driven electron trap and an atomic oven fabricated through 3D printing via Laser Powder Bed Fusion (L-PBF). Our findings show that these components can support stable, narrow-band, high-amplitude oscillations of the electric field at the electrodes, making them suitable for simultaneous trapping of ions.

Key highlights include:
- Successful integration of the trap into a coaxial microwave cavity
- Effective performance of the atomic oven in UHV environments with minimal outgassing
- Investigation of long-term pressure variations and their potential impact on electron-ion trapping experiments

These results pave the way for future experiments in microwave detection and the study of low-energy ion-electron interactions at room temperature.

A big thank you to our collaborators and the entire team:
Vineet Kumar, Niklas V. Lausti, Jiří Hajnyš, Ivan Hudák and David Motyčka, Adam Jelínek

We're excited about the potential of this research and look forward to your feedback!
