Ablation Removal of Transport-Blocking Defects in Surface-Electrode Ion Traps
Toby Maddock, Parsa Rahimi, Matthew Aylett +3
We demonstrate in situ removal of a transport-blocking defect on a surface-electrode ion trap device using a Q-switched Nd:YAG 532 nm pulsed ablation laser. This approach eliminate…

In-vacuum surface flashover of SiN, AlN, and etched SiO2 thin films at micrometre scales
Vijay Kumar, Martin Siegele-Brown, Matthew Aylett +2
We investigate the surface flashover voltage threshold for SiO, SiN, and AlN thin films over micrometre scale lengths. Furthermore, we test the effects of different etching che…
