Available in PDF, EPUB and Kindle. Book excerpt: Motivated by planned double beta decay experiments in 76Ge I describe a computational model for the electric fields of solid state diode detectors and the subsequent charge transport. Aspects of detector performance determined by the impurity charge concentration are explored in a series of measurements of comparable point contact" p-type germanium detectors and compared to our computational model. In particular, we measure the capacitance of the germanium detector as a function of the bias voltage to determine the free parameters in a three parameter model of the impurity charge density, selectively mapping out the density at all points within the detector volume. We then use our impurity charge density map to determine the sensitivity of pulse shape analysis applied to various classes of physics events detected in the crystal. When possible, the impact of our refinements on a figure-of-merit for double-beta decay experiments is described.

This book was released on 2016 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrode segmentation is a necessity to achieve position sensitivity in semicon- ductor radiation detectors. Traditional segmentation requires decreasing electrode sizes while increasing channel numbers to achieve very fine position resolution. These electrodes can be complicated to fabricate, and many electrodes with individual electronic channels are required to instrument large detector areas. To simplify the fabrication process, we have moved the readout electrodes onto a printed cir- cuit board that is positioned above the ionization type detection material. In this scheme, charge from radiation interactions will be shared amongst several electrodes, allowing for position interpolation. Because events can be reconstructed in between electrodes, fewer electrodes are needed to instrument large detector areas. The prox- imity charge sensing method of readout promises to simplify detector fabrication while maintaining the position resolution that is required by fields such as home- land security, astrophysics, environmental remediation, nuclear physics, and medical imaging. We performed scanning measurements on a proof of principle detector that we fabricated at Lawrence Berkeley National Laboratory (LBNL). These measurements showed that position resolution much finer than the strip pitch was achievable using the proximity charge readout method. We performed analytic calculations and Monte Carlo modeling to optimize the readout electrode geometry for a larger detector to test the limits of this technology. We achieved an average position resolution of 288 [mu]m with eight proximity electrodes at a 5 mm pitch and 1 mm strip width, set 100 [mu]m away from the detector surface by a Kapton spacer. To achieve this resolution using standard technologies, 300 [mu]m pitch strips are necessary, and would require 100 channels to instrument the same area. Through our optimization calculations, we found that there is a trade-off between position resolution and energy resolution,2 and this system provided comparatively poor energy resolution by HPGe standards, with 4.7 keV FWHM at 59.5 keV. With another electrode geometry, we were able to achieve 2.9 keV FWHM at 59.5 keV. This dissertation describes the work we completed to achieve these results.

Available in PDF, EPUB and Kindle. Book excerpt: Semiconductor sensors patterned at the micron scale combined with custom-designed integrated circuits have revolutionized semiconductor radiation detector systems. Designs covering many square meters with millions of signal channels are now commonplace in high-energy physics and the technology is finding its way into many other fields, ranging from astrophysics to experiments at synchrotron light sources and medical imaging. This book is the first to present a comprehensive discussion of the many facets of highly integrated semiconductor detector systems, covering sensors, signal processing, transistors and circuits, low-noise electronics, and radiation effects. The diversity of design approaches is illustrated in a chapter describing systems in high-energy physics, astronomy, and astrophysics. Finally a chapter "Why things don't work" discusses common pitfalls. Profusely illustrated, this book provides a unique reference in a key area of modern science.
