Detector R&D

To complement the Detector Pool, the group pursues R&D activities aimed at enabling unique detector capabilities not commercially available. We have chosen to focus our efforts on two areas for detector R&D: superconducting energy-dispersive detectors and semiconducting pixelated detectors. Each development is linked to scientific strategic goals of the APS, as well as leveraging local detector initiatives (i.e., superconducting cosmology detectors at ANL/HEP/UChicago and ASIC development at Fermilab). This serves to provide a well-balanced R&D portfolio for the group.

Hybrid Pixel Detectors

FASPAX schematicWe are developing hybrid pixel array detectors. We have two initiatives. FASPAX (Fermi-Argonne Semiconductor Pixel Array X-ray detector) is an integrating detector with wide dynamic range and high burst frame rate for dynamic studies. VIPIC (Vertically Integrated Photon Imaging Chip) is an effort to develop a detector specifically optimized for ultra-fast x-ray photon correlation spectroscopy (XPCS) in collaboration with BNL and FNAL.

Superconducting Detectors

Thermal kinetic inductance detectorWe are developing energy-dispersive x-ray detectors using superconducting circuits. Specifically, we are working on microwave kinetic inductance detectors and transition edge sensor microcalorimeters.

Fast CCD

FCCD2A collaboration between APS and LBNL to develop the FastCCD series of highly parallel readout direct-detection CCD cameras. The Fast CCD2 operates in a frame store mode with a 1Mpixel imaging area (30 micron pixels) currently running at 100 fps (sustained rates), but will eventually run at 200 fps in 1 MPixel mode. Faster rates are aavailable over smaller ROI (e.g., 960 x 92 pixels @ 1000 fps and plans for 5000 fps for 960 x 12 pixels.

Germanium Strip Detector

Ge sensor wire bonded to BNL's HERMES ASICIn collaboration with Brookhaven National Laboratory, we are developing Germanium strip detectors for energy-dispersed and powder diffraction.

Beamline Electronics

APS timing diagramWe have developed flexible analog and digital electronics hardware to meet the needs of the APS beamlines. Typically, the digital electronics are used for timing and synchronization at the beamlines. The architecture consists of an FPGA, microcontroller and IO components. We also have expertise in analog electronics (e.g., low-noise electrometers, V2F converters, and CCD readouts).


We have developed detector-specific software (e.g., DetectorMPI for real-time detector processing) which maybe of interest to others.
