Description

Successful operation of the APS facility requires a very stable particle beam. Vibration coupled through mechanical systems, such as magnet supports, beam tube supports, and other paths can cause deterioration of the particle beam. There are two sources of vibration: external, or far field, which is generated external to the APS site and internal, or near field, which is generated on site and associated with operation of the facility. Internal vibration sources can be controlled or minimized using good design practices to eliminate or reduce vibration amplitudes of machinery and equipment. Depending on their origin, external vibration sources may or ... continued below

Description

Successful operation of the APS facility requires a very stable particle beam. Vibration coupled through mechanical systems, such as magnet supports, beam tube supports, and other paths can cause deterioration of the particle beam. There are two sources of vibration: external, or far field, which is generated external to the APS site and internal, or near field, which is generated on site and associated with operation of the facility. Internal vibration sources can be controlled or minimized using good design practices to eliminate or reduce vibration amplitudes of machinery and equipment. Depending on their origin, external vibration sources may or may not be controllable, therefore it is necessary to have sufficient knowledge of their amplitude level and frequency content to predict any adverse effects on the operation of the APS facility. The primary objective of this study was to measure the far field ground vibration at the 7 GeV site over long time periods to get an accurate representation of its frequency and amplitude characteristics.
