Development of a Scintillating Fibre Detector for HERA-B
A fibre detector with multianode PM readout for high rate applications was developed for the HERA-B spectometer to cover the area near the beampipe. Such a detector has to operate at particle rates up to 2 ⋆ 10 mms and has to tolerate a radiation dosis up to 1 Mrad/y. The light output of test detectors with different scintillating fibres was measured as well as the light transport through clear...
متن کاملTime Resolution and Linearity Measurements for a Scintillating Fiber Detector Instrumented with VLPC’s
The time resolution for charged particle detection is reported for a typical scintillating fiber detector instrumented with Rockwell HISTE-IV Visible Light Photon Counters. The resolution measurements are shown to agree with a simple Monte Carlo model, and the model is used to make recommendations for improved performance. In addition, the gain linearity of a sample of VLPC devices was measured...
متن کاملCMOS X-rays detector array based on scintillating light guides
This paper describes a pixel imaging array consisting in 400 m × 400 m photodiodes fabricated in CMOS technology. An array of scintillating CsI:Tl crystals is placed above the photodiodes. These crystals are encapsulated in aluminum walls, forming a light path that guides the visible light produced by the scintillating crystal into the photodiodes. In this way, the X-ray energy is first convert...
متن کاملThe Front-End electronics for the LHCb scintillating fibres detector
The LHCb detector will be upgraded during the next LHC shutdown in 2018/19 [1]. The tracker system will have a major overhaul. Its components will be replaced with new technologies in order to cope with the increased hit occupancy and radiation environment. A detector made of scintillating fibres read out by silicon photomultipliers (SiPM) is studied for this upgrade. Even if this technology ha...
متن کاملFinite detector based projection model for high spatial resolution.
For finite detector and focal spot sizes, here we propose a projection model for high spatial resolution. First, for a given x-ray source point, a projection datum is modeled as an area integral over a narrow fan-beam connecting the detector elemental borders and the x-ray source point. Then, the final projection value is expressed as the integral obtained in the first step over the whole focal...
