Description
A compact 1.3 GHz linear particle accelerator (linac) is currently under development to extend the range of applications of the pulsed low-energy positron system (PLEPS) located at the Forschungs-Neutronenquelle Heinz Maier-Leibnitz (FRM II). The linac is based on a side-coupled radio-frequency (RF) cavity (SCC) geometry to reduce footprint and power consumption. However, conventional fabrication of SCCs faces significant thermal and mechanical limitations which influence the linac's performance. Laser Powder Bed Fusion (L-PBF) has already demonstrated the ability to produce monolithic pure copper cavities, enabling a complex integrated cooling system and reducing manufacturing time and costs. We aim to transfer this potential to the required 1.3 GHz SCC, making this the first fully additively manufactured SCC developed for a real experimental application. This work presents the first fundamental design of the required SCC geometry. The electromagnetic field distribution was optimized using simulation tools such as CST Studio. Beam dynamics studies conducted using TraceWin code demonstrate capabilities of the proposed linac concept.
