RasClic: A Long Base, Low Frequency, High Precision Seismograph
'Afstudeer-Colloquium' Mark Beker (TU-Delft)
Monday, November 3, 15:30 hr, room H220
RasClic, a three point, long base alignment system has proven it can meet the stringent alignment tolerances of the proposed next generation accelerator, CLIC. It consists of a light source, a diffraction plate and an image sensor. By monitoring the position of the a diffraction pattern on the image sensor a measure for the relative positions of the three components is obtained.
Development beyond these alignment tolerances could lead to applications in other fields of science. By following the movement of the Earth's crust on a nanometer scale, RasClic can be used as a low frequency, high precision seismograph. The development of the system and review of it's potential as a seismograph are the main objectives of this research.
