The DPF Instrumentation Award and DPF Instrumentation Early Career Award are bestowed annually to honor exceptional contributions to instrumentation advancing the field of particle physics through the invention, refinement, or application of instrumentation and detectors. The awards recognize accomplishments in one or more of the following areas:
The DPF Instrumentation Award recognizes outstanding achievements in particle physics instrumentation that have had a major impact on the field through the awardee’s dedication over a substantial portion of an entire career, while the DPF Instrumentation Early Career Award recognizes achievements having a significant impact at an early career stage. For the purpose of this award, the early career stage is taken to be approximately 15 years from a Ph.D. or other terminal degree, with due account for interruptions and other factors in nominees’ careers.
Award recipients will present award lectures at the 2019 CPAD December meeting.
Nominations need the following components:
Nominations will be active for three years.
The DPF Instrumentation Award 2019 is presented by the APS Division of Particles and Fields (DPF) to:
For his seminal contributions to and sustained development of the use of liquid xenon and argon detectors for direct detection searches for dark matter, including the two-phase technique.Today, liquid xenon (LXe) and liquid argon (LAr) 2-phase time-projection chambers (TPCs) are the leading technologies for direct detection searches for weakly interacting dark matter above 10 GeV, with liquid argon having competitive reach below 10 GeV.This state of affairs is in great part due to early and continued work by Wang. Wang began work on the development of LAr TPCs in the late 1980s with ICARUS at CERN, a direct precursor to the DUNE experiment.For his dissertation in the 1990s, he shifted to the study of LXe for dark matter detection, during which he made critical contributions with collaborators: observing the measurement of ionization with proportional scintillation in single-phase and proportional electroluminescence in dual-phase LXe, the latter of which critically set the basis for discrimination of electron recoils from nuclear recoils; and demonstrating the liquid purification needed to achieve the ionization drift lengths required for large detectors.A 2-kg chamber he developed for his dissertation laid the foundation for work by the ZEPLIN and XENON10 collaborations, which demonstrated leading limits on dark matter with 2-phase LXe for the first time in 2007 and 2008.Over the past 20 years, Wang has continued to be one of the technical wizards behind the fast progress in LXe and LAr detectors, developing designs for very high voltage feedthroughs, power fail-safe cryogenic systems, and low-radioactivity TPCs for the XENON100 and XENON-1T LXe and DarkSide-50 LAr detectors, which have all produced world-leading limits on dark matter. He currently is leading the cryogenics and TPC systems for the DarkSide-20k detector under construction.
The DPF Early Career Instrumentation Award 2019 is presented by the APS Division of Particles and Fields (DPF) to:
Ana Amelia Machado and Ettore Segreto
For the invention and development of the ARAPUCA photon detector, a novel and effective tool for measuring scintillation light in liquid argon detectors.The greatest challenge for the detection of the VUV (127 nm) scintillation photons in a large liquid-argon volume is attenuation.An ARAPUCA consists of a small volume with highly reflective internal surfaces and acceptance windows made from short-pass dichroic filters coated with two different wavelength shifters, one on each side. The external shifter converts the 127 nm photons into photons with a wavelength below the filter’s cutoff, where it is transparent. The inner wavelength shifter shifts the light to a wavelength above the cutoff where the filter is reflective. The net result of this process is that the photon is trapped inside the highly reflective box where it is detected by the photo-sensors (SiPMs) on the internal surface. The ARAPUCA named for a Brazilian bird trap, thus traps the photons and results in much more effective light collection capability than previous devices.
Nominators should submit all of the material listed above, except the supporting letters. The names and email addresses of the supporting letter-writers should also be included in the nomination packet. If you encounter difficulty with the site, contact Bob Bernstein (firstname.lastname@example.org).
It is important to remember the membership of APS is diverse and global, so the Prize and Award winners as well as Fellows of the APS should reflect that diversity. Nominations of women, members of underrepresented minority groups, and scientists from outside the United States are especially encouraged. Nominations of qualified junior scientists are especially welcome this year and in subsequent odd-numbered years.

The DPF Instrumentation Award 2018 is awarded to Professor Rinaldo Santonico from the University of Rome, Tor Vergata, for the development of large gap Resistive Plate Chambers (RPCs) and their successful application in a wide variety of experiments.
Since the initial proposal in 1981, Professor Santonico and his group have continually evolved this technology over a period of more than 30 years. The good time and spatial resolution of RPCs and their relatively low cost per unit area make RPCs the technology of choice for modern collider and astro-particle detectors that need to cover large areas for charged particle tracking in low-occupancy environments. Through the definition of detailed construction procedures for mass production of large quantities of RPCs and the transferral of this technology to industry, Professor Santonico has enabled many other groups and applications around the world, within and outside of HEP.
The DPF Instrumentation Early Career Award 2018 is awarded to Dr. Javier Tiffenberg from Fermilab and the University of Chicago for the development of the Skipper CCD and its application in light dark matter and coherent neutrino-nucleus interaction searches.
Skipper CCDs have first been reported in 1990, but Dr. Tiffenberg has realized the potential of this technology for the detection of low-energy signals. Profiting from two decades of development in CCD technology, Dr. Tiffenberg’s group was able to modify the readout stage of the CCD such that it can readout the exact number of electron-hole pairs in a single pixel and do so over a very large dynamic range, thus gaining sensitivity to single photons hitting the detector.
