Abstract | This paper presents a development of a seismic sensor for the future Compact Linear Collider (CLIC). Sensor in which three different types of sub-nanometre displacement transducers have been integrated: a Fabry-Pérot interferometer, an optical encoder and a capacitive transducer. This sensor allows us to compare the resolution of all the transducers under the same conditions, thus enabling us to verify the most suitable transducer for a seismic sensor. The best resolution of 28.8 pm was achieved with the optical encoder. This in combination with ease of installation makes it an ideal candidate for a seismic senor for CLIC. |
