New Publication from the MADECOLD Consortium! Researchers at the University of Stuttgart have published an important new study in Applied Sciences titled “A Small Linear Accelerator for Charged Microparticles.” The work presents a newly developed 6‑stage, 120 kV electrostatic linear accelerator designed to accelerate micron‑sized particles to precisely controlled speeds.
The research presents the design and development of a six-stage, 120kV Linear Accelerator (LINAC) capable of accelerating micro-sized charged particles to speed of up to 1300 m/s. The system can deliver acceleration ratios up to ×3 and can operate at rates of up to 33 particles per second. The LINAC autonomously selects the required number of acceleration stages to reach a target speed range, providing high flexibility for laboratory experiments.
This compact and efficient accelerator supports applications such as dust‑sensor calibration, impact physics and particle‑based surface processing and contributes directly to MADECOLD Project’s mission of advancing electrically driven particle acceleration technologies as a cutting-edge solid-state additive manufacturing (AM) technique.
Through this approach, MADECOLD is paving the way for the construction of multi-material structures with exceptional precision, build rate, and the ability to control individual particles for surface processing at unprecedented scales.
Congratulations to the University of Stuttgart MADECOLD team for this outstanding contribution to the project’s mission and to the wider research community!
