Abstract
A well-logging apparatus may include a charged particle source, a target electrode, and an accelerator column. The accelerator column may include a housing extending between the charged particle source and the target electrode, a series of spaced apart accelerator electrodes carried by the housing, a series of ring-shaped resistors surrounding the housing, and a respective connector coupling adjacent ones of the series of ring-shaped resistors together and to a corresponding one of the series of spaced apart accelerator electrodes.

A well-logging apparatus comprising:
- a charged particle source;
- a target electrode;
- and
- an accelerator column comprising
- a housing extending between said charged particle source and said target electrode,
- a series of spaced apart accelerator electrodes carried by said housing,
- a series of ring-shaped resistors surrounding said housing, and
- a respective connector coupling adjacent ones of said series of ring-shaped resistors together and to a corresponding one of said series of spaced apart accelerator electrodes;
- wherein each connector comprises:
- an electrically conductive ring coupling the adjacent ones of said series of ring-shaped resistors and defining a resistor tap point;
- and
- at least one electrically conductive link coupling the corresponding one of said accelerator electrodes to a corresponding tap point;
- and
- wherein the adjacent ones of said series of ring-shaped resistors have recessed edges defining a channel to receive a corresponding one of said electrically conductive rings.
A method for making an accelerator column for charged particles comprising:
- coupling a series of spaced apart accelerator electrodes along a housing;
- coupling a series of ring-shaped resistors to surround the housing, wherein each respective ring-shaped resistor is radially contiguous around an axial position along the accelerator column;
- and
- coupling a respective connector between adjacent ones of the series of ring-shaped resistors and to a corresponding one of the series of spaced apart accelerator electrodes,
- wherein coupling the respective connector comprises:
- positioning an electrically conductive ring to couple the adjacent ones of the series of ring-shaped resistors and defining a resistor tap point;
- and
- using at least one electrically conductive link to couple the one of the accelerator electrodes to a corresponding tap point, and
- wherein adjacent ones of the series of ring-shaped resistors have recessed edges defining a channel to receive a corresponding one of the electrically conductive rings.
