Transverse wake effects in an optical waveguide IFEL accelerator

Description: A recent proposal describes a project to build a short demonstration stage IFEL accelerator using as input beam the output of the Accelerator Test Facility high brightness linac (ATF) currently under construction at BNL. A second stage of the proposal involves the design and construction of a GeV IFEL accelerator. Both IFEL accelerators could be built using standard focussing as discussed in the proposal. While this is fairly natural in the short (60cm) demonstration accelerator, it requires mu… more

High Pressure Source/Cryostat Relief Solutions

Description: This report addresses solutions to the potential problem of cryostat over pressurization by the nominal 65 psi MWAP LAr source dewar. Uncontrolled (by reason of failure) filling of a 15 psi MW AP cryostat by the LAr fill line could cause over pressurization by overwhelming the provided cryostat relief system. Three levels of protection against over pressurization by the source dewar are mentioned in this report; the reduced (operational) relief pressure, the source pressure regulator, and the L… more

Ion dip spectroscopy of cold molecules and ions. Progress report and renewal proposal

Description: A research program is underway with the objective of developing techniques of high resolution multiphoton spectroscopy for selective, ultrasensitive molecular detection. Methods under study include various forms of ion dip spectroscopy and new methods of ion fragmentation spectroscopy. The studies are providing a new understanding of the fundamental spectroscopy and photophysics of large molecular ions. Dimer and cluster ions of polynuclear aromatics and related species are also being investiga… more

Aviation Safety: FAA Near Midair Collision Reports

Description: This report discusses the minimum separation distance in a near midair collision report which the event must meet in order to be classified a "near miss." If a pilot of flight crew member subjectively believes that the near miss occurred, the report of that event is accepted by the Federal Aviation Administration (FAA) and counts as a near miss in the FAA data base regardless of the actual separation distance. While no proximity limits are placed on near midair collision reports, the agency doe… more
