IDEA #6EPYBI Semiconductor Detectors For Nuclear Radiation Spectrometry

NUCLEAR(cid:3)ENERGY(cid:3)AND(cid:3)SAFETY SEMICONDUCTOR DETECTORS FOR NUCLEAR RADIATION SPECTROMETRY Description Semiconductor detectors are among the most important devices employed for the spectral analysis of nuclear radia$ tion, although the type of semiconductor detector to be used depends on the specific problem to be resolved. The Depar$ tment of Radiation Physics at the Kyiv Institute for Nuclear Research has devel$oped the following types of detectors: Surface$barrier detectors of total absorption (Е$de$ 1. tectors) based on high$ohmic silicon n$ and p$ type semiconductors for nuclear radiation spectrometry. 2. Charged$particle energy$loss (dE/dx) detectors used in telescopes for the determination charged particles masses in composite nuclear reactions. 3. Drift silicon$lithium detectors (Si (Li)$detectors) based on silicon compensated to lithium used for the spectral analysis of charged particles. Innovative Aspect and Main Advantages The developed semiconductor detectors will be for nuclear measurements in charged particle accelerators. These de$ tectors are characterized by a high energy resolution and high sensitivity over a wide range of energies. Areas of Application The detectors will be utilized for the spectrometry of nuclear radiation. Stage of Development The detectors are developed are produced based on antici$ pated performance parameters different nuclear problems. Fig. 1.
