Abstract
An apparatus that comprises material which have different thermal expansion coefficients, combined in such a way that the length of the drift region is variant, and self adjusting with temperature. The adjustment is such as to compensate for the length changes resulting from thermal expansion or contraction in other ion optical elements, such that ions of substantially equivalent mass to charge ratios maintain a constant flight time though the system. This allows for use of standard construction methods for the ion optical elements.
