Time of flight tubes and methods of using them

摘要

Certain embodiments described herein are directed to time of flight tubes comprising a cylindrical tube comprising an inner surface and an outer surface, the cylindrical tube comprising an effective thickness and sized and arranged to couple to and support a reflectron assembly inside the cylindrical tube. In some configurations, the cylindrical tube further comprises a conductive material disposed on the inner surface of the cylindrical tube, the conductive material present in an effective amount to provide a field free region for ions when the conductive material is charged.

1. A time of flight tube comprising:
an inner tube comprising an effective thickness and sized and arranged to couple to and support a reflectron assembly inside the inner tube, the inner tube comprising a conductive metal material disposed on an inner surface of the inner tube, the conductive metal material present in an effective amount to provide a field free region for ions when the conductive material is charged from a current applied to the conductive metal material; an outer tube surrounding the inner tube, the outer tube effective to insulate the inner tube and electrically isolate the inner tube such that the current applied to the conductive metal material of the inner tube is not provided to the outer tube; and an air gap between the inner tube and the outer tube.
