It is argued that the future for the engineer in the solar technologies is bright as the US Energy Research and Development Administration (ERDA) is coming to grips with the challenges offered to assure the US' energy supplies and about the role of the engineering profession in accomplishing that task. ERDA's role of "option generator" is described. In

ERDA of solar selective absorbers
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1996Abstract ERDA (elastic recoil detection analysis) with 200 MeV I beams was used during the development of new solar selective absorber materials (TiN x O y and AlCu x Fe y ). Depth profiles of the light and heavy components were measured simultaneously using a detector system with particle identification.

Abstract Heavy ion ERDA (HIERDA) has so far been implemented mainly at accelerator facilities with beam energies between 10 and 100 MeV. This is an energy region where gas ionization chambers allow for good resolution and particle identification. Using an ionization chamber with a very thin patterned SiN entrance window heavy ions with an energy of a

ERDAS ist ein integriertes, rasterbasiertes Bildverarbeitungsund geographisches Informationssystem. Bei der Entwicklung wurde besonderen Wert auf die Implementierung und Berucksichtigung bestehender, bzw. sich kunftig abzeichnender Standards und auf eine moglichst weitgehende Unabhangigkeit von Spezialhardware gelegt.

Determining mass separation between scattered and recoiled particles by measuring the TOF parameter of neutral or ionic species was first used at low energies; for example at the end of the seventies, Chen and coworkers studied gold targets using 8-keV Ar+.(1) The MeV ERDA techniques were used for many years, but these were principally applied in ...

Simulation of surface roughness effects in ERDA
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1998The program SURF has been developed to simulate surface roughness effects in elastic recoil detection analysis (ERDA). The Program calculates the recoil energy spectrum from a sample with a rough surface from a superposition of spectra, each corresponding to a subdivision of the beam spot.

ERDA with very heavy ion beams
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1996Abstract The use of very heavy ion beams such as 127I or 197Au with 1–2 MeV/u makes ERDA (elastic recoil detection analysis) a quite universal technique for thin film analysis capable of analyzing simultaneously light and heavy elements including H with almost constant sensitivity.

ERDA Research in Fracturing Technology
Proceedings of SPE Eastern Regional Meeting, 1976Abstract Research in fracturing technology for the ERDA organization is structured on (1) the development of new concepts for increasing the deliverability of natural gas from resources that are classified as marginal by present day practices and (2) the testing and transfer of practices and (2) the testing and ...
