1. An ion mobility detector system, comprising:
an ion mobility detector hardware subsystem comprising a drift tube, a drift tube grid, and an ion gate grid; and
a drift tube voltage driving subsystem comprising:
a high voltage (HV) base module having a first power supply configured to generate a first high-voltage output and a second power supply configured to generate second high-voltage output;
an interconnect module configured to electrically and physically couple the HV base module to a HV deck module, the interconnect module comprising a first switch assembly to selectively couple the first high-voltage output to a node to produce a node voltage, and a second switch assembly to selectively couple the second high-voltage output to the node; and
the HV deck module configured (i) to receive the node voltage, (ii) to generate a grid voltage that floats on the node voltage, and (iii) to convey the node voltage to the drift tube grid and the grid voltage to the ion gate grid of the ion mobility detector hardware subsystem.
