Keynote talk
With the Gas Pixel Detector (GPD), the class of micro-pattern gas detectors has reached a complete integration between the gas amplification structure and the read-out electronics. To obtain this goal, three generations of application-specific integrated circuit of increased complexity and improved functionality has been designed and fabricated in deep sub-micron CMOS technology. This...

Gas Pixel Detectors
Oral Contribution
A low background Micromegas detector was operating at the sunrise side of the CAST (CERN Axion Solar Telescope) experiment during the first phase of the experiment (2002-2004). This detector, constructed of low radioactivity materials, operated efficiently and achieved a low background level of around 5x10-5 counts/keV/cm2/s in the 2-4 keV region. This performance was accomplished by...

Gas Pixel Detectors
Oral Contribution
For its physics program with a high-intensity hadron beam of 2 x 10^7 particles per second, the COMPASS experiment at CERN requires tracking of charged particles scattered by very small angles with respect to the incident beam direction. While good resolution in time and space is mandatory, the challenge is imposed by the high beam intensity, requiring radiation-hard detectors which add very...

Gas Pixel Detectors
Oral Contribution
A new type of radiation detector based in the spherical geometry is presented. The detector consists of large spherical gas volume with central electrode and radial electric field. Charges deposited in the drift volume are drifting to the central sensor where are amplified and collected. We introduce a new spherical proportional sensor located at the center of curvature acting as a...
