Model SP-500
This unique instrument has been developed for the US Department of Energy for use as a wide passband highly sensitive vibration sensor in the beam focusing system of linear super-colliders (very high energy particle accelerators). As such this sensor is radiation hardened and functions normally in extremely strong magnetic fields – up to 6 Tesla.
PMD/eentec electrochemical seismic sensors are the only ones among all known sensors that can adequately perform in such environments. The sensors were successfully tested in magnetic fields up to 1T at the Stanford Linear Accelerator Center (SLAC) and demonstrated complete immunity to the field.
Each seismometer has a single component sensor that can work as either horizontal or vertical with the sensitivity axis in the direction indicated by the arrow. The sensor is essentially isotropic – i.e. it will perform equally well in any random orientation. Its extremely small dimensions fully answer severe space limitations imposed by the linear colliders focusing systems.
The sensors are planned for use on the International Linear Collider (ILC).
PMD/eentec is working on further improvements of the SP-500 characteristics, in particular, increasing its sensitivity and extending frequency response toward very long periods.
