        parts: an inner shield that minimizes the low
        terminal-to-guard capacitance, and an
        outer shield (the case) that minimizes the
        detector input capacitance and noise.                        INNER SHIELD                                      CHL

        3-terminal capacitance substituter with low
        zero capacitance.
