Abstract:
Presented are specific moments from the design process of a
detector hybrid for space research mass-spectrometric applications. The
hybrid consists of a silicon multipixel solid-state detector and the
adjacent readout electronics. This is a special development for the
purposes of the suprathermal time-of-flight sensor STOF of the CELIAS
spectrometric system on the ESA/NASA scientific satellite SOHO, launched
in December 1995. The detector hybrid concept was used after
SOHO/CELIAS/STOF in the energy-and-charge analyzer SEPICA (Solar
Energetic Particle Ionic Charge Analyzer) on ACE (Advanced Composition
Explorer), in orbit since 1997. The idea of creation of detector hybrid
is not a new one. It emerged in conformity to the development of the
nuclear high energy experiments in direction to the increase of the
information volume from one side, and from the other side in improvement
towards a more precise particle registration. The main problems of the
conventional organization of signal processing in concern to the
low-noise transmission of analog signals are to a great extent solved
with the development of a single chip multichannel amplifier readout
electronics connected to the solid-state detector diodes in one
assembly.
