Upgrades of a Small Electrostatic Dust Accelerator at the University of Stuttgart

In this paper, we describe the upgrade of a small electrostatic dust accelerator located at University Stuttgart. The newly developed source, focusing lens, differential detector and linac stage were successfully installed tested in beam line. input voltage range source was extended from 0–20 kV to 0–30 kV. A with two charge sensitive amplifiers is employed monitor particles speeds several m/s km/s surface charges above 0.028 fC. post-stage provides an additional acceleration ability total up 120 entire system works without protection gas complex high terminal. volumes be pumped down are can quickly evacuated. new used accelerate micron- submicron-sized metal or coated mineral materials. Improvements allow for wider variety materials applications.
