X-ray Imaging with ePix100a, a High-Speed, High-Resolution, Low-Noise Camera
Blaj, Gabriel.
The ePix100A camera is a 0.5 megapixel (704 768 pixels) camera for low noise x-ray detection applications requiring high spatial and spectral resolution. The camera is built around a hybrid pixel detector consisting of 4 ePix100a ASICs flip-chip bonded to one sensor. The pixels are 50 um 50 um (active sensor size ~ 35.4 mm 38.6 mm), with a noise of ~ 180 eV rms, a range of 100 8 keV photons, and a current frame rate of 240 Hz (with an upgrade path towards ~ 10 kHz). This performance leads to ... Show Full Abstract
The ePix100A camera is a 0.5 megapixel (704 768 pixels) camera for low noise x-ray detection applications requiring high spatial and spectral resolution. The camera is built around a hybrid pixel detector consisting of 4 ePix100a ASICs flip-chip bonded to one sensor. The pixels are 50 um 50 um (active sensor size ~ 35.4 mm 38.6 mm), with a noise of ~ 180 eV rms, a range of 100 8 keV photons, and a current frame rate of 240 Hz (with an upgrade path towards ~ 10 kHz). This performance leads to a camera combining a high dynamic range, high signal to noise ratio, high speed and excellent linearity and spectroscopic performance. While the ePix100A ASIC has been developed for pulsed source applications (e.g., free-electron lasers), it performs well with more common sources (e.g., x-ray tubes, synchrotron radiation). Several cameras have been produced and characterized and the results are reported here, along with x-ray imaging applications demonstrating the camera performance. Show Partial Abstract
