We propose to use a torsion pendulum to measure the force between macroscopic (of the order of few centimetres) flat metallic plates at distance of the order of 10 microns. We present the experimental setup and discuss how to cope with crucial aspects like absolute distance mea- surement and plates parallelism. We also discuss how the modulation at a proper frequency and amplitude of plates distance can help in disentangling the different forces contribution acting at such short distances.

Abstract
We propose to use a torsion pendulum to measure the force between macroscopic (of the order of few centimetres) flat metallic plates at distance of the order of 10 microns. We present the experimental setup and discuss how to cope with crucial aspects like absolute distance mea- surement and plates parallelism. We also discuss how the modulation at a proper frequency and amplitude of plates distance can help in disentangling the different forces contribution acting at such short distances.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
