At the German National Institute, the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, a miniature trap was designed to store Yb with a ring of 1.3 mm diameter. The oven and the filament act as compensation electrodes to control ion micro-motion in three dimensions [35]. 

Micro Ag-ring electrodes Recently, Uchida et al. proposed micro Ag-ring electrodes whose diameter is similar to that of a carbon-ring... 

Typical cyclic voltammograms of micro Ag-ring electrode of 1.2 m dip diameter, obtained in a deoxygenated 0.1 M KNO3 solution and in a 2 mM hydroxyethyl viologen solution containing 0.1 MKNO3 are shown in Fig. 3.
