FIG. 1.

This image shows a composite bolometer with a Ge active layer (detector A). The NTD thermistor gold wires are not connected to the readout pads.

FIG. 2.

(a) Scatter plot showing the relationship between the amplitudes of the pulses acquired in coincidence from the main absorber (-axis) and from the active layer (-axis) for detector A; (b) the same plot after imposing coincidences with pulses from detector C. Not only the surface events have been cut, but also “mixed” events due to cosmic muons releasing their energy both in the main absorber and in the active layer.

FIG. 3.

Scatter plot showing the relationship between the amplitudes of the pulses acquired in coincidence from the main absorber (-axis) and from the active layer (-axis) for detector B. In the inset, the energy spectrum obtained by selecting surface events is shown. The expected structure of the source spectrum emerges clearly, proving that the selection of the surface events is effective.

Image of FIG. 4.
FIG. 4.

(Color) (a) Rise time distribution for the pulses developed across the active layer thermistor in detector B. (b) A detail of the scatter plot reported in Fig. 3 where fast active-layer pulses [left Gaussian in (a)] are reported in blue, while slow active-layer pulses [right Gaussian in (a)] in green.
