DLA structures are five to six orders of magnitude smaller than conventional radio frequency accelerating structures. Precision of the microfabrication process will be crucial for the construction of a practical DLA device. In this study, finite-element method models are constructed for selected DLA structures to show what level of precision, in terms of a fraction of the driving wavelength, is required. Some speculation on the possible tuning of imperfect structures will also be presented.
