Fixed tilt solar collector employing reversible vee-trough reflectors and vacuum tube receivers for solar heating and cooling systems. Final report. JPL Publication 77-78

Description: The objective of the Vee-Trough/Vacuum Tube Collector (VTVTC) Project was to prove the usefulness of vee-trough concentrators in improving the efficiency and reducing the cost of collectors assembled from evacuated tube receivers. The VTVTC was analyzed rigorously and various mathematical models were developed to calculate the optical performance of the vee-trough concentrator and the thermal performance of the evacuated tube receiver. A test bed was constructed to verify the mathematical analy… more

Paleozoic-Mesozoic Boundary in the Berry Creek Quadrangle, Northwestern Sierra Nevada, California

Description: Abstract: Structural and petrologic studies in the Berry Creek quadrangle at the north end of the western metamorphic belt of the Sierra Nevada have yielded new information that helps in distinguishing between the chemically similar Paleozoic and Mesozoic rocks. The distinguishing features are structural and textural and result from different degrees of deformation. Most Paleozoic rocks are strongly deformed and thoroughly recrystallized. Phenocrysts in metavolcanic rocks are granulated and dra… more

Magnitude and Frequency of Floods in California

Description: From purpose and scope: This report describes methods for evaluating the magnitude and frequency of floods at gaged and (or) ungaged sites in California. The purpose is to provide a base for the study of floods and the review and extension of flood magnitude-frequency relations by agencies and individuals who are concerned with the management and control of floods, highway construction, and other related work.

Lawrence Berkeley Laboratory Accelerator Division Annual Report: 1975

Description: The Bevatron/Bevalac is operated, maintained, and continually improved as a national research facility for studies in nuclear science and in biology and medicine. Recent modifications have brought the 21-year-old synchrotron to the threshold of tremendously exciting new studies as the world's most powerful heavy-ion accelerator. In its Bevalac configuration, the machine capitalizes on the coupling of the SuperHILAC to the Bevatron via a 175-meter beam line. The SuperHILAC acts as an injector to… more
