Quadrula mortoni, Specimen #962

Description: One preserved mussel specimen including both the left and right valves. The specimen exhibits a round shape; moderately thick shell; white internal coloring; dark brown external coloring; external sculpturing in the form of pustules. Collected in the San Jacinto basin. The specimen measures between 0 - 60 mm in length and was assessed to be relatively-recently dead when collected.

Active readout KAP x-ray spectrometer. [Laser-produced plasma diagnostics]

Description: It was found that a new type of solid-state detector known as the self-scanning photodiode array can be used to obtain the active readout of data in wavelength-dispersive x-ray spectrometers. The use of this device to recover x-ray spectral data for glass microspheres heated by Lawrence Livermore Laboratory's CYCLOPS laser is reported. The self-scanning photodiode array is a product of the MOS electronics fabrication technology. It consists of an array of semi-discrete diffused junction photodi… more

Spectral measurements of x-rays and electrons emitted from 1. 06. mu. m laser produced plasmas

Description: Absolute spectral measurements were made of electrons escaping from plasmas produced by focusing 5-10 J, 50-100 picosecond, 1.06 ..mu..m laser pulses on 10 ..mu..m thick Parylene disk targets. Nine spectral bands with 3 to 7.5 keV resolution were obtained from 30 to 190 keV using a 90/sup 0/ focusing permanent magnet spectrometer and appropriately positioned silicon electron detectors.

X-ray line spectra from DT filled SiO/sub 2/ microshells

Description: This paper is a discussion of curved crystal x-ray spectrometry of laser induced plasmas for h..nu.. < 4 keV. The plasmas were produced by a short pulse (<200 ps) of 1.06 ..mu.. (neodymium glass) radiation on glass shells on the order of a hundred ..mu..m in diameter and a micron thick. Total absorbed laser energy is of the order of 10 joules and x-radiation .01-.1 joule/sr. The shells were filled with DT gas under compression.

Lawrence Berkeley Laboratory Accelerator Division Annual Report: 1972-1974

Description: The Accelerator Division was formed as a separate division of the Lawrence Berkeley Laboratory in 1973. Originally called Physics II Division, it acquired its present title when Andrew M. Sessler was designated Director of the Laboratory in November 1973. Under the leadership of Associate Director Edward J. Lofgren the major activities of the Division comprise operation of the Bevalac, for high-energy and heavy-ion physics, and Advanced Accelerator Research and Development. In addition, there i… more
