Well-logging apparatus with ring-shaped resistors and related methods

摘要

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.

1. 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; andat 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.
