The International Symposium on the Development of Detectors for Particle, Astro-Particle and Synchrotron Radiation Experiments was hosted by the Stanford Linear Accelerator Center, April 3-6, 2006. This is the 9th conference in a series that was started in 1977 jointly by SLAC and the Budker Institute for Nuclear Physics at Novosibirsk.

In recognition of the fact that the research program at many High Energy Physics Laboratories is going to change dramatically in the years to come the program for this year's Symposium covered detector development for experiments in three different areas of research:  Particle Physics, Astro-Particle Physics, as well as experiments at Synchrotron Radiation Facilities. The emphasis was on detectors and sensors that are based on fundamentally similar concepts and properties of matter. The goal of this Symposium was to bring together experts from these different communities to exchange information and stimulate interdisciplinary developments.

The Symposium was sponsored by the U.S. Department of Energy, the Stanford Linear Accelerator Center and Stanford University.
