Abstract
A time-sharing computer was used in conjunction with a semi- conductor detector and radioisotopic sources to evaluate energy dispersion x-ray analysis for the rapid analysis of copper-base alloys. The time-sharing computer served two purposes: to aid in the development of the analytical method and to simulate the action of a dedicated computer that would eventually be used as part of an on-line analytical device. Some of the general capabilities of time- sharing computers are discussed in this paper with some emphasis on the differences between the computer requirements of energy dispersive x-ray methods and conventional x-ray spectrography. An annular source of americium 241 was used with a secondary fluorescer to excite 23 brass and bronze alloys. The 400-channel spectrum from a multichannel analyzer was recorded on paper tape. A telephone coupled teletype was used to transmit the x-ray spectrum to the central processing facility. Curve fitting and statistical analysis programs similar to those available from most commercial time- sharing computer operations were utilized as well as other programs written at the College Park Metallurgy Research Laboratory for processing digitized spectra.
