N2 - The limiting characteristics of intermediate mass bolometers cooled to low temperature for the detection of single events are analyzed over a large energy range with the contributions of inherent noise at low energy, of statistical effects at intermediate energy, and of nonlinear effects at high energy. The optimal design of a fast (time constant τ < 1 ms) intermediate mass bolometer (10 mg < m < 1 g) with high resolution (ΔEFWHM < 500 eV) and large dynamic range (E(max) 5 MeV) is described from functional block diagram to the calculation of parameters for each element. This has been applied to the construction and successful tests of a 100 mg silicon bolometer. We obtained resolutions better than 1 keV on γ-rays from 13 to 130 keV with a base line resolution of 300 eV and a measured time constant of less than 400 μs. The same bolometer was also used for α particle spectrometry in the 5 to 8 MeV range with a resolving power greater than 200. From measurements of the short lived 214Po atoms recoiled into the bolometer we deduced a half-life of 160 ± 12 μs, which extends the excellent time resolution possible with such bolometers.
