Abstract

In the years 1980s and 1990s, a very fast and important progress on position and energy loss measurements of elementary particles was obtained by the use of Si strip detector in high energy (HE) experiments. The number of strips has been increasing at any improvement of the tracker device. The high number of strip density also pushed the power reduction of the readout electronic amplifiers. The Si tracker became at certain moment a challenging substitute of the classical spark chambers (Fichtel et al. NASA-TM-X-70761, 1995; Thompson arXiv:e:0811.0738, 2008), in use for tracking particles in space experiments. In particular in HE \(\gamma \)-strophysics, the photon direction was derived by measuring that of the positron electron pair produced in high Z material interlaid in the planes of the spark chamber. See for instance the EGRET figure in the text. AGILE and GLAST (renamed Fermi after launch) are the most successful examples of the Si revolution.

Notes

Acknowledgements

I am happy to thank the small group of researchers from INFN Trieste responsible for the AGILE Si tracker construction and their leader Dr. Michela Prest. The contribution of the industries coordinated by the Carlo Gavazzi Space: Orlikon Contraves Telespazio, Alcatel Alenia Space Mipot has been exceptional, showing a passion for the project very similar to that of the proponents of the mission. Let me mention the enthusiasm and the far looking attitude of PI Marco Tavani, including his effort to get all the local (Indian) dignitaries in our favor at the launch moment. I am sorry, if very probably, I have missed some people that was and is essential for the fantastic achievements of the AGILE Mission. I would like also to thank again Michela Prest, Marco Feroci, Claudio Labanti and Andrea Argan for helping me with their advices in the review of the paper and Michele Palatiello for taking care of the LaTeX  paper layout.
