The first three-dimensional simulation study of thin multi-line readout cables using finite element simulation tool RAPHAEL is being reported.
The compactness of the γ-camera head, thin detectors matrix, electronic readout and collimator, facilitates the detection of close γ sources with the advantage of a high spatial resolution.
X-rays are converted to light in a layer of thallium-doped CsI, then the light is converted to electrical signals by a-Si photodiodes and the signal is multiplexed to the readout electronics by thin-film transistors (TFT) consisting of a-Si deposited on a glass substrate.
These include thinner detector chips and faster readout rates, which will greatly enhance the signal-to-noise ratio at high resolution, improvements in specimen preparation, the use of supports that are less prone to move under electron bombardment, and new image recording procedures that reduce beam-induced movement.
The biasing resistors are made of p-doped polysilicons and the coupling capacitors are built by separating implanted strips and readout strips by a thin oxide layer.

The ongoing program to develop a custom hybrid pixel detector for the innermost layers of the tracking system of the PANDA experiment foresees thinned epitaxial silicon sensors and pixel readout electronics based on 130 nm CMOS technology.
MATERIALS AND METHODS: The digital radiography system is based on a large-area flat-panel x-ray detector with a structured cesium iodide scintillator layer and an amorphous silicon thin-film transistor array for image readout.
The detector concept is based on thin layers of silicon sensors with fast readout.
