Experimental results about tests on a commercial power bricks under radiations is presented. The experimental obtained results are very interesting in order to evaluate the possibility to use particular electronic device, which can be used in harsh environment. The power bricks tested in this paper highlights interesting technical specification.
Radiation detectors built in high-voltage and high-resistivity CMOS technology are an interesting option for the large area pixel trackers sought for the upgrade of the Large Hadron Collider experiments. A possible architecture is a hybrid design, where CMOS sensors are readout by front-end electronics coupled through a thin dielectric layer. A critical requirement is the radiation hardness of both...
We present the first results of a tracking system prototype using the artificial retina algorithm for fast track finding. The system is based on extensive parallelization and interconnectivity, and allows real-time tracking with offline-like quality with a latency < 1 μs. The artificial retina algorithm has been implemented on a novel custom data acquisition board, based on commercial FPGAs, that...
The performance in magnetic field (B-field) of a DC-DC converter ad hoc designed for LHC operation has been evaluated. The tests have been carried out at the Laboratorio Acceleratori e Superconduttività Applicata (LASA), in Milan (Italy), in the first months of 2014 and the experimental results are here presented and discussed. The ability to operate in hostile environment of the tested DC-DC converter...
We present the design for the first prototype of a tracking system with “artificial retina” for fast track finding. The “artificial retina” is a tracking algorithm inspired by neurobiology and based on extensive parallelization of data distribution and pattern recognition. It allows track finding with a latency < 1 µs and with track parameter resolutions that are comparable with offline reconstruction...
As the LHC luminosity is ramped up to 3 and beyond, the high rates, multiplicities, and energies of particles seen by the detectors will pose a unique challenge. Only a tiny fraction of the produced collisions can be stored offline and immense real-time data reduction is needed. An effective trigger system must maintain high trigger efficiencies for the physics...
We studied the feasibility of monolithic silicon-germanium front-ends for cryogenic semiconductor detectors. In this framework we designed and simulated a low-noise Charge Sensitive Preamplifier for High Purity Germanium detectors using the Austria Micro System S35 silicon-germanium technology. The preamplifier uses two silicon-germanium Hetero-junction Bipolar Transistors, a few silicon Metal-Oxide-Silicon...
The SuperB asymmetric e+ e- collider has been designed to deliver a luminosity greater than 1036 cm-2 s-1 maintaining moderate beam currents. Comparing to current B-Factories, the reduced center-of-mass boost of the SuperB machine requires an improved vertex resolution to allow precision measurements sensitive to New Physics. Therefore the SuperB Silicon Vertex Tracker will be equipped with an innermost...
As the LHC luminosity is ramped up to 3×1034 cm-2 s-1 and beyond, the high rates, multiplicities, and energies of particles seen by the detectors will pose a unique challenge. Only a tiny fraction of the produced collisions can be stored on tape and immense real-time data reduction is needed. An effective trigger system must maintain high trigger efficiencies for the physics we are most interested...
