Grid connected wind energy conversion systems (WECS) present interesting control demands, due to the intrinsic nonlinear characteristics of windmills and electric generators. In this paper a direct adaptive control strategy for WECS control is proposed. It is based on the combination of two control actions: a radial basis zfunction network-based adaptive(More)
The current paper describes the design of Fiber Optics Links for BTeV’s Pixel Detector readout. BTeV pixel detectors chips will be located as close as 6mm from the accelerator’s beam into the vacuum pipe. The readout electronics will be located at about 6cm from the beam, imposing strong constrains regarding radiation, mass, power dissipation, and size. The(More)
The readout noise for Charge-Coupled Devices (CCDs) has been the main limitation when using these detectors for measuring small amplitude signals. A readout system for a very low noise scientific CCD is presented in this paper. The Skipper CCD architecture, and its advantages for low noise applications are discussed. A technique for obtaining sub-electron(More)
Fully depleted thick CCDs have been designed for infrared astronomy, but their low read-out noise of the order of &#x2248;2e<sup>-</sup> and their considerable mass of &#x2248;5.2 gr, allows novel uses for them in low energy threshold particle detection applications, such as the CONNIE and DAMIC experiments. For both experiments, a reduction of the CCD(More)
In this article a stochastic model for point events expected in the output image of scientific CCDs is derived. This kind of events are typical in CCD systems dedicated to particle detection, such as DAMIC and CONNIE. The model includes the randomness of the charge movement in the silicon and the noise at the readout stage providing the base for an optimal(More)
One of the keystones of the canceled BTeV experiment (proposed at Fermilab’s Tevatron) was its sophisticated threelevel trigger. The trigger was designed to reject 99.9% of lightquark background events and retain a large number of B decays. The BTeV Pixel Detector provided a 3-dimensional, high resolution tracking system to detect B signatures. The Level 1(More)
