- Acoustic Leak Detection for District Heating Systems
- An acoustic leak detection facility was completed and used to evaluate the capability of piezoelectric sensors, accelerometers, and capacitance microphones to detect and locate gas and water leaks in underground district heating and cooling (DHC) piping. Leak detection sensitivity and location capabilities for DHC systems were estimated from laboratory data and from data obtained from the underground DH system in Scranton, Pennsylvania, where acoustic background noise levels and acoustic signals from field-induced steam leaks were acquired. Acoustic detection of leaks with flow rates of less than 10 gpm is possible at a distance of several hundred meters, with a location accuracy of a few meters. Although steam leaks of comparable mass loss can be detected over a similar range with transducers mounted on the pipe outer wall, location accuracy of a few meters over this range may only be possible with transducers in direct contract with the steam. Intrusive sensors may also be necessary to detect and locate leaks in plastic pipe.

- Annex to 7-GeV Advanced Photon Source : Conceptual Design Report
- The Annex to the 7-GeV Advanced Photon Source Conceptual Design Report updates the Conceptual Design Report of 1987 (CDR-87) to include the results of further optimization and changes of the design during the past year. The design changes can be summarized as affecting three areas: the accelerator system, conventional facilities, and experimental systems. Most of the changes in the accelerator system result from inclusion of a positron accumulator ring (PAR), which was added at the suggestion of the 1987 DOE Review Committee, to speed up the filling rate of the storage ring. The addition of the PAR necessitates many minor changes in the linac system, the injector synchrotron, and the low-energy beam transport lines. 63 figs., 18 tabs.

- In this document we present the characteristics of the electromagnetic radiation from various types of sources on the 7-GeV Advanced Photon Source (APS) storage ring. The sources include bending magnets, undulators, and wigglers. The characteristics are compared with those of other synchrotron sources when operated at their design specifications. The influence of positron beam size on the on-axis brilliance is discussed, along with the power distribution from these sources. The goal of this document is to provide users with enough information on the characteristics of radiation from the APS storage ring so that experiments can be efficiently planned.

- Formation of Lubricating Films at Elevated Temperatures from the Gas Phase
- Abstract: Conventional liquid lubricants, when subjected to temperatures of 250*C and above for extended time in an air atmosphere, degrade rapidly to make large amounts of solid sludge and deposits. Based on boundary lubrication of bearings, these same lubricants, when subjected to 250*C to the melting point of the bearing metal, produce in the micro- to milli-second residence time in the bearing contact enough "friction polymer" to result in good lubrication. This report describes the use of these conventional liquid lubricants delivered in a homogeneous vapor phase where the carrier gas is nitrogen, air or mixtures of these two gases. The lubricants studied include alkyl and aryl phosphate esters, organic acid esters, polyphenyl ethers, and mineral oil.
