Ray-tracing image simulations of transparent objects with complex shape and inhomogeneous refractive index
Armin Kalita, Bryan Oller, Thomas Paula +18
Optical images of transparent three-dimensional objects can be different from a replica of the object's cross section in the image plane due to refraction at the surface or in the…
Radiation Hardness Study of the ePix100 Sensor and ASIC under Direct Illumination at the European XFEL
I. Klačková, K. Ahmed, G. Blaj +10
The ePix detector family provides multiple variants of hybrid pixel detectors to support a wide range of applications at free electron laser facilities. We present the results of a…
Robust Pixel Gain Calibration with Limited Statistics
G. Blaj, G. Haller, C. J. Kenney
Pixel detectors typically display pixel-to-pixel gain variation of a few percent which result in reduced spectroscopic performance. We have developed a calibration method which rel…
Hammerhead, an ultrahigh resolution ePix camera for wavelength-dispersive spectrometers
G. Blaj, D. Bhogadi, C. -E. Chang +7
Wavelength-dispersive spectrometers (WDS) are often used in synchrotron and FEL applications where high energy resolution (in the order of eV) is important. Increasing WDS energy r…
Ultrafast processing of pixel detector data with machine learning frameworks
Gabriel Blaj, Chu-En Chang, Christopher J. Kenney
Modern photon science performed at high repetition rate free-electron laser (FEL) facilities and beyond relies on 2D pixel detectors operating at increasing frequencies (towards 10…
Performance of ePix10K, a high dynamic range, gain auto-ranging pixel detector for FELs
G. Blaj, A. Dragone, C. J. Kenney +17
ePix10K is a hybrid pixel detector developed at SLAC for demanding free-electron laser (FEL) applications, providing an ultrahigh dynamic range (245 eV to 88 MeV) through gain auto…
Dead-time correction for spectroscopic photon counting pixel detectors
Gabriel Blaj
Modern photon counting pixel detectors enabled a revolution in applications at synchrotron light sources and beyond in the last decade. One of the limitations of current detectors…
Characterization of the ePix100a and the FastCCD Semiconductor Detectors for the European XFEL
I. Klačková, G. Blaj, P. Denes +6
The European X-ray Free Electron Laser (EuXFEL) is a research facility providing spatially coherent X-ray flashes in the energy range from 0.25keV to 25keV of unprecedented brillia…
Detector Damage at X-Ray Free-Electron Laser Sources
G. Blaj, G. Carini, S. Carron +8
Free-electron lasers (FELs) opened a new window on imaging the motion of atoms and molecules. At SLAC, FEL experiments are performed at LCLS using 120 Hz pulses with 10^12 to 10^13…
Analytical Solutions of Transient Drift-Diffusion in P-N Junction Pixel Sensors
G. Blaj, C. J. Kenney, J. Segal +1
Radiation detection in applications ranging from high energy physics to medical imaging rely on solid state detectors, often hybrid pixel detectors with (1) reverse biased p-n junc…
