EPI Crossbeam Foot

Document #:

LIGO-D020195-x0

Document type:

D - Drawings

Abstract:

The output block for the HEPI system. 2x HEPI Actuators push on this block: one vertical and one horizontal. One end of a Crossbeam (HAM or BSC) is mounted rigidly to the Foot (the Crossbeam's other end is mounted to the Foot of the opposing HEPI). 2x HEPI Offload Springs mount to the back of the Foot, to support a share of the weight of the Support Structure + ISI + payload.

This part is also known as the "HEPI Boot".
