As described in the journal Review of Scientific Instruments, which is produced by the AIP Publishing, a team of researchers within the LAPPD collaboration developed an advanced facility for testing large area photodetectors -- with a level of spatial precision measured in micrometers and time resolutions at or below a picosecond.
"Innovation in science often comes from advances in instrumentation," said Matthew Wetstein, a Grainger Fellow at the University of Chicago's Enrico Fermi Institute who was a co-author on the study. "It can come in the form of a completely new capability or be as simple as making existing instrumentation affordable and accessible for many different types of experiments.
In many areas of particle physics, detectors have seen steady improvements in resolution, but timing is an envelope that deserved a push, he added.
"We’re designing detectors that are the fastest ever built for their spatial granularity, size, and cost," Wetstein said. "Our goal is to put a very powerful tool into the hands of the scientific community."
A central aspect of the project is a technique known as Atomic Layer Deposition (ALD), the authors reported in their paper. Beyond the realm of high-energy physics, potential applications for the photodetector range from basic X-ray physics to medical imaging to large-area X-ray detection for homeland security.
The article, "A Test Facility for Large-Area Microchannel Plate Detector Assemblies Using a Pulsed Sub-picosecond Laser" by Bernhard Adams, Matthieu Chollet, Andrey Elagin, Eric Oberla, Alexander Vostrikov, Matthew Wetstein, Razib Obaid, and Preston Webster is published in the journal Review of Scientific Instruments.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
