Compression Pack Inspection

Document #:

LIGO-S1800574-v4

Document type:

S - Serial numbers

Abstract:

The cleaning and particle observation of Compression Packs. This will be cleaned at Caltech.
The bottom half of the compression pack is labeled sample 1.
The top half is labeled sample 2.

An AmScope microscope was used to take images of the particles. A calibration microscope slide is used for an accurate average count (1 Div = 0.01 mm)

The container was cleaned using a siled edge wipe soked in 1% liquinox solution, rinsed with DI water and dryed with a top-gun. pictures before and after are attached
