Subject: Comment sem4160 SNF 2012-12-12 11:34:05: optimized the column and aperture alignments
From: jwc@snf.stanford.edu

at 5 KV I went through each section on the column.
Column is now well aligned and offers exceptional resolution and performance for an
anolog tool.
5kV 5 mm WD aperature strip No 4 ( smallest movable aperture) resolution is 3 to 4 nm
on silicon AFM tapping mode cantilever.
USERS ARE REMINDED TO PLEASE NOT TRANSLATE THE MOVABLE APERTURE STIP VERY FAR FROM ITS
SET POSITIONS. IF YOU ARE HAVING TROUBLES PLEASE CONSULT WITH ANY EXPERIENCED OPERATOR,
OR YOUR FAVORITE BEAM TOOLS STAFF MEMBER
