Abstract:
1. An assembly comprising a multi-component electrode and a peripherally engaging electrode carrier, wherein: the peripherally engaging electrode carrier comprises a carrier frame and a plurality of reciprocating electrode supports; the carrier frame comprises an electrode accommodating aperture; the multi-component electrode is positioned in the electrode accommodating aperture and comprises a silicon front face bonded to a non-silicon, electrically conductive backing plate; the backing plate comprises a plurality of mounting recesses formed about its periphery; the reciprocating electrode supports are configured to reciprocate between an inner electrode-engaging periphery and an outer retracted periphery; the inner electrode-engaging periphery is smaller than the electrode accommodating aperture; the outer retracted periphery is larger than the inner electrode-engaging periphery; and the mounting recesses of the backing plate and the reciprocating electrode supports of the electrode carrier are positioned such that the reciprocating electrode supports can be reciprocated into and out of the mounting recesses by moving the reciprocating electrode supports between the inner electrode-engaging periphery and the outer retracted periphery.
