13. Ramping Up the SNS Beam Power with the LBNL Baseline H- Source.

Abstract

LBNL designed and built the Frontend for the Spallation Neutron Source, including its H- source and Low-Energy Beam Transport (LEBT). This paper discusses the performance of the H- source and LEBT during the commissioning of the accelerator, as well as their performance while ramping up the SNS beam power to 540 kW. Detailed discussions of major shortcomings and their mitigations are presented to illustrate the effort needed to take even a well-designed R&D ion source into operation. With these modifications, at 4% duty factor the LBNL H- source meets the essential requirements that were set at the beginning of the project. [ABSTRACT FROM AUTHOR]

16. Pedestrian excitation of bridges.

Abstract

This paper reviews the evidence on dynamic bridge loading caused by moving pedestrians. The phenomenon of 'synchronization' by which people respond naturally to an oscillating bridge when this has a frequency close to their natural walking or running frequency is a feature of this phenomenon. By increasing modal damping, synchronization can be prevented, but how much damping is needed in any particular situation? If some simplifying assumptions about how people walk are made, it is possible to predict analytically the minimum damping required to ensure that synchronization does not lead to high vibration levels. The main assumption is that the movement of a pedestrian's centre of mass has two components. One is its natural movement when the person is walking on a stationary pavement. The other is caused by movement of the pavement (or bridge) and is in proportion to pavement amplitude but with a time delay that is arbitrary. When the time delay is a 'worst case', pedestrians act as a source of negative damping. This theory supports the adoption of a non-dimensional number which measures the susceptibility of a bridge to pedestrian excitation. Although currently there are not many good bridge response data, predictions using this non-dimensional number are compared with the data that are available and found to be in satisfactory agreement. Both lateral and vertical vibrations are considered. [ABSTRACT FROM AUTHOR]

22. Power Flow between a Class of Coupled Oscillators.

Author

Newland, D. E.

Abstract

The equation of mean power flow between two groups of randomly excited oscillators is derived from first principles. Subject to the coupling satisfying certain requirements, it is shown that a new parameter-the average natural frequency shift of the oscillators owing to the coupling-determines the power flow between the two groups. Power flow is directly proportional to the natural frequency shifts and to the oscillator densities (modal densities) in each group. It is suggested that this formulation has advantages over the conventional 'coupling-loss-factor' equation of the statistical energy approach to noise-transmission problems. [ABSTRACT FROM AUTHOR]
