Summary:
The Large Area Picosecond Photodetector (LAPPD) collaboration has developed big detectors that push the timing envelope, measuring the speed of particles with a precision down to trillionths of a second.

The Large Area Picosecond Photodetector (LAPPD) collaboration has developed big detectors that push the timing envelope, measuring the speed of particles with a precision down to trillionths of a second.

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 authors of this study are affiliated with Argonne National Laboratory, SLAC, the University of Chicago, the Illinois Institute of Technology and Arizona State University.
