Book excerpt: Techniques are described in detail that have been developed for the manufacture of encapsulated surface-barrier particle detectors. The devices manufactured to date have found use as counters and spectrometers for fission fragments, alpha particles, and low-energy electrons from radioactive nuclei. Devices, 50 mm sq. in area, have a resolution for 6.1-Mev alpha particles of 26 kev at room temperature and 18 kev at 78 deg K. Resolution for 1.1-Mev electrons has been measured as 7.5 kev at 78 deg K for devices 25 mm sq. in area. The silicon used has been n-type, grown with a 111 orientation, and purchased in the form of ingots about 2 cm in diameter; the resistivity has ranged from 100 to 3000 ohm-cm.
