  An HPGe detector equipped with a transistor reset preamplifier and readout
with a CAEN DT5781 fast pulse digitizer was employed in the measurement of
X-rays from kaonic lead at the DA$\Phi$NE $e^+e^-$ collider at the Laboratori
Nazionali di Frascati of INFN. A thin scintillator in front of a lead target
was used to select kaons impinging on it and to form the trigger for the HPGe
detector. We present the results of the kaonic lead feasibility measurement,
where we show that the resolution of the HPGe detector in regular beam
conditions remains the same as that without the beam and that a satisfactory
background reduction can be achieved. This measurement serves as a test bed for
future dedicated kaonic X-rays measurements for the more precise determination
of the charged kaon mass.
