The

**stability**of the interferometer has been measured in a vacuum chamber bykeeping the temperature fluctuation around lOmk. A single mirror was used to

avoid unwanted displacement of mirror N relative to mirror M. Long term

Let us consider the

distance, Af/f/ r ; t Is the lasting of the measurement; we take Af/f as an estimation

of sf/f: sf/f = Af/f. From data sheet of the EDM Hewlett Packard 3850A (Smith, 1980
