Ion trap with gold-plated alumina: substrate and surface characterization

Myunghun Kim, Keumhyun Kim, Jungsoo Hong +7

We describe a complete development process of a segmented-blade linear ion trap. Alumina substrate is characterized with an X-ray diffraction and loss-tangent measurement. The blad…
