CES setup monitoring

Version: 1.5 2003-04-19 ThD

CES setups

This page keeps track of the encoder values, and micrometer values of the latest setup at a given wavelenght. In general the reproducability is good on short time scales, and even between light path changes. The long term stability is not so good however, hence this monitoring effort.

So every time you make a change, please make an entry in the following tables using the script update_setup to enter the values along with any relevant comments. See the paragraphs below the tables for more instructions.

Setups in order of decreasing wavelength. Old setups included following the most recent one. Most recent setup for a given wavelength on a colored background, old setups on white background
