Segmentation of ion traps is a promising route to allow the major results in trapped-ion quantum computing to be extended beyond individual traps to many-ion-trap systems. Additionally, the ability afforded by segmented traps to tailor the confining potential allows qualitatively new problems to be addressed, such as applications to quantum simulations. The use of tailored trap potentials for simulations of solid-state systems are discussed, and experimental progress to this end is outlined. We also report on the characterisation of a laser-machined, gold-on-alumina segmented trap which has been made according to a standardised ``pan-European microtrap design". Operation of this trap is compared to others used by different institutions in Europe.
