Book Description
The measured response characteristics of lithium drifted silicon radiation detectors at 295 deg. K and 79 deg. K are presented for protons with energies from 31.5 to 350 MeV; for positive pions with energies from 50.2 to 206 MeV; and for electrons with energies from 265 keV to 767.2MeV. Analysis of the energy loss spectra confirms that the energy is being deposited by the protons and pions in the silicon purely through collision losses, whereas it appears that the silicon absorbs additional energy lost by the high energy electrons through interaction of the bremsstrahlung radiation in the depletion region. The charge collection efficiency determined by gamma rays is shown to agree with the charge collection efficiency determined by minimum ionizing particles. Nonlinear effects caused by unequal electron and hole trapping lengths and surface effects lead to reduced charge collection efficiencies for low energy electrons which do not completely penetrate the detector depletion region, in agreement with theory and with observations in the x-ray region. Apparent recombination effects also lead to reduced charge collection efficiencies at low field or for protons with energies below about 100 MeV under constant bias conditions. The present data support the conclusion that the charge conversion factor at any one temperature is constant to with 1% for electrons, pions and protons over the entire energy span measured.

Book Description
This second open access volume of the handbook series deals with detectors, large experimental facilities and data handling, both for accelerator and non-accelerator based experiments. It also covers applications in medicine and life sciences. A joint CERN-Springer initiative, the "Particle Physics Reference Library" provides revised and updated contributions based on previously published material in the well-known Landolt-Boernstein series on particle physics, accelerators and detectors (volumes 21A, B1,B2,C), which took stock of the field approximately one decade ago. Central to this new initiative is publication under full open access
