Monoenergetic pulsed proton beams at energies of 1 and 3 MeV per proton have been employed to characterize a segmented double-sided silicon strip detector. The detector is manufactured from a neutron transmutation doped silicon wafer and features a bulk resistivity of $2300~\Omega \cdot \text {cm}$ . Signals from both P-side and N-side strips have been digitized at 14 b, 100 MS/s. The beam was focused...
In this work we compare different calibration sources and focus on their combination to optimize the calibration of large-format X-ray imagers over a wide range. This activity is carried out in the framework of the DSSC project and the primary aim is the calibration of the DSSC camera. We considered pulsed IR laser, radioactive sources, X-ray tube, electrical injection devices, X-ray synchrotron beam,...
FARCOS (Femtoscope ARray for Correlation and Spectroscopy) frontend has to feature a dynamic range up to half GeV with 4 different selectable gain values and an energy resolution of the order of 10 keV FWHM. 16-channel charge preamplifiers are integrated in a single chip in AMS 0.35μm C35B4C3 technology. In order to experimentally probe the achievable dynamic range, we exploited the pulsed monoenergetic...
In the framework of the construction of a novel Femtoscope Array for Correlation and Spectroscopy, named FARCOS, aiming at the identification in charge and mass even of particles stopping in the first detection layer, we are performing a thorough characterization of the silicon detector layers in terms of the collection properties as a function of the point of incidence. We have experimental evidence...
We successfully evaluated the possibility of using a pulsed monoenergetic proton beam as a diagnostic tool for semiconductor detectors' response mapping at high charge densities. In order to ease the setup of the detector under test we explored the opportunity of performing tests with protons in air. We qualified a polyimide film window (Upilex-S, 7.5 μm nominal thickness) as proton extraction window...
A highly segmented Double-Sided Silicon Strip Detector has been characterized using mono-energetic pulsed beams of protons (1 and 3 MeV) and carbon (13 MeV). The detector was manufactured from a Neutron Transmutation Doped (NTD) silicon wafer yielding a bulk resistivity of 2.3 kOhm cm. In this work we show the interstrip effects caused by the beam striking only one strip and the beam on both the strip...
We exploited the possibility of using a pulsed mono-energetic proton beam (DEFEL beam-line @ LABEC, Italy) able to provide bunches of protons with tunable energies for detector qualification, diagnostics and calibration. This allows qualification of the response of the detector-front end system over a wide range of calibrated charge levels, with high precision in space and time, reaching the highest...
Owing to the fully 3D topology of Multi-Linear Silicon Drift Detectors (MLSDD) and since the longitudinal coordinate is measured from the electron drift time, an accurate calibration of the relationship drift time vs. drift coordinate is needed and the dependence of the time-resolution and longitudinal position-resolution on the ionization profile has to be evaluated. In this work we performed a detailed...
We are currently developing a novel detection system, named FARCOS (Femtoscope Array for Correlation and Spectroscopy) and featuring high angular and energy resolution and able to reconstruct particle's momentum at high precision for different physical cases in multi-fragmentation nuclear physics experiments. Performing a Pulse Shape Analysis on signals coming from the ΔE stages -Double Sided Silicon...
In this work we present the experimental qualification of the longitudinal profile of the charge cloud in Multi-Linear Silicon Drift Detectors at high charge levels. This is accomplished by means of a custom-developed deconvolution algorithm, based on the conjugate gradient method that extracts the actual shape of the anode current by deconvolution of the output waveforms of the frontend preamplifier...
We exploited the possibility of using a pulsed mono-energetic proton beam - coming from the DEFEL beam-line of the Tandetron accelerator at LaBEC (Laboratorio di Tecniche Nucleari per i Beni Culturali) in Sesto Fiorentino, Italy - as a diagnostic tool for the characterization of the response of semiconductor detectors at high charge densities. In fact accelerated protons owing to their limited range...
