The X-ray Response of Silicon Drift Detectors
A new discrete analytic calculation of the spectral response of silicon drift detectors for X-rays is developed and compared with measurements using monochromatic synchrotron radiation in the 0.2 to 1.9 keV energy range in order to explain the observed background. The calculations are in good agreement with the measurements for secondary electron charge cloud widths σsec of (85±7) nm below and ...
متن کاملSilicon Drift Detectors for High Resolution, High Count Rate X-ray Spectroscopy at Room Temperature
Silicon Drift Detectors (SDDs) consist of a fully depleted volume in which an electric field drives signal charges to a small sized anode. Due to their topology SDDs combine a large sensitive area with a small output capacitance. In an advanced SDD version for X-ray spectroscopy designed and fabricated at the MPI semiconductor laboratory the input transistor of the amplifying electronics has be...
متن کاملAvalanche Amplification in Silicon Drift Detectors
A novel device which combines advantages of Silicon Drift Detector and Silicon Avalanche Diode on the same silicon wafer is proposed. Avalanche ampliication is applied to cloud of drifting electrons in order to improve detection of radiation with low energy deposition coeecient. Principle and optimal conditions for the operation of this new detector based on Avalanche Ampliier are discussed.
متن کاملMonte-carlo Modeling of Silicon X-ray Detectors
A new 3-D Monte-Carlo code, X-Tracker, was developed to model internal events that occur as X-ray photons are absorbed within Si(Li) detectors. The goal was to model the performance of state-of-the-art detectors, including peak shapes, background and artifact peaks found in clean spectra from collimated radioactive and other X-ray sources. The model includes the influence of collimation, fr...
متن کاملState-of-the-art Silicon Detectors for X-ray Spectroscopy
The semiconductor laboratory of the Max-Planck-Institutes for physics and for extraterrestrial physics develops and fabricates silicon sensors for scientific experiments in astronomy and highenergy physics, as well as for industrial applications. Among them are state-of-the-art detectors for X-ray imaging and spectroscopy. Their common features are the integration of the readout electronics on ...
