Channel Analyzer

Multi-channel Analyzer (MCA) is one of very essential equipment in nuclear physics and nuclear engineering for the measurement of ionization radiation. Generally, an MCA system consists of radiation detector, amplifier system, ADC circuit, and MCD connected with computer for data processing. Among them, ADC is a functional electronic block, which plays an important role for converting analog to digital signals. Corresponding to the domestic needs in development of nuclear instruments, this work presents a design and construction of an ADC8K module with successive approximation method. Some experimental results are as follows: Differential non-linearity (DNL%) = 1.42, Integral non-linearity (INL% = 0.58), and χ2 = 8.109 proved that mentioned system can be used with considerable reliability in practical nuclear engineering.

Nuclear Engineering and Technology for the 21st Century - Monograph Series Jovica Riznic, Series Editor With more than 75 years of combined working experience in the area of reactor physics and safety, the intention of the authors of this monograph is to provide a practical book on reactor physics, particularly for the safe operation of aged CANDU reactors, with minimal mathematics or equations. The book gives a glimpse of first principles and their engineering application in reactor physics, for those who are interested in or are working in the Canadian nuclear industry. The book is also ideal as a reference for physicists, operators, regulatory staff, and for those who need to interact with reactor physicists at CANDU sites, nuclear laboratories, institutes, universities, or engineering companies. This book assumes prior knowledge of nuclear physics offered at the secondary level. As very few equations appear in the monograph, it is not considered suitable for specialists whose focus is only on calculations or on the development of software on reactor physics. Such readers should refer to the books listed in the bibliography at the end of the monograph.

Capture Cross Sections

Neutron-induced cross section is one of the key quantities in nuclear physics and nuclear engineering. The integral experiment can give good feedback to the cross sections with low uncertainties. Using the optical model and statistical model, the neutron-induced total and capture cross sections of153Eu are revaluated according to the experimental microscopic total cross sections and the PROFIL-2 integral experiment. The corresponding uncertainties and covariances are determined with the data assimilation method implemented in CONRAD code. On the other hand, the previous interpretation of the PROFIL-2 experiment showed that JEFF-3.1 overestimates the neutron-induced capture cross section of 151 Eu by a factor of 2. Further analysis performed in the present work points out that the large difference between calculation and experimental data is mainly due to the lack of152m1 Eu in ERANOS code, which was used to interpret the PROFIL-2 experiment. The correction of 152m1Eu on the interpretation largely reduces the difference between JEFF-3.1 and PROFIL-2 and shows the agreement between the PROFIL-2 integral experiment and other microscopic measurements. The revaluated neutron-induced total and capture cross sections of 151 Eu and 153Eu correspond well with both the microscopic experimental measurements and the PROFIL-2 integral experiment.

Nuclear Processes

SummaryIsotopic shifts in the lines of the heavy elements in Ap stars, and the characteristic abundance pattern of these elements point to the fact that we are observing mainly the products of rapid neutron capture. The peculiar A stars may be treated as the show windows for the products of a recent r-process in their neighbourhood. This process can be located either in Supernovae exploding in a binary system in which the present Ap stars were secondaries, or in Supernovae exploding in young clusters. Secondary processes, e.g. spontaneous fission or nuclear reactions with highly abundant fission products, may occur further with the r-processed material in the surface of the Ap stars. The role of these stars to the theory of nucleosynthesis and to nuclear physics is emphasized.
