Beam power scale-up in MEMS based multi-beam ion accelerators
Q. Ji, K. K. Afridi, T. Bauer +9
We report on the development of multi-beam RF linear ion accelerators that are formed from stacks of low cost wafers and describe the status of beam power scale-up using an array o…
Compact, directional neutron detectors capable of high-resolution nuclear recoil imaging
I. Jaegle, P. M. Lewis, M. Garcia-Sciveres +10
We report on the design, production, and performance of compact 40-cm Time Projection Chambers (TPCs) that detect fast neutrons by measuring the three-dimensional (3D) ionizati…
Multi-beam RF accelerators for ion implantation
Peter A. Seidl, Arun Persaud, Diego Di Domenico +10
We report on the development of a radio frequency (RF) linear accelerator (linac) for multiple-ion beams that is made from stacks of low cost wafers. The accelerator lattice is com…
Design and Implementation of a Thomson Parabola for Fluence Dependent Energy-Loss Measurements at the Neutralized Drift Compression eXperiment
F. Treffert, Q. Ji, P. A. Seidl +10
The interaction of ion beams with matter includes the investigation of the basic principles of ion stopping in heated materials. An unsolved question is the effect of different, es…
Waferscale Electrostatic Quadrupole Array for Multiple Ion Beam Manipulation
K. B. Vinayakumar, A. Persaud, P. A. Seidl +5
We report on the first through-wafer silicon-based Electrostatic Quadrupole Array (ESQA) to focus high energy ion beams. This device is a key enabler for a wafer based accelerator…
Demonstration of a compact linear accelerator
