Enhancing the sensitivity of the LUX-ZEPLIN (LZ) dark matter experiment to low energy signals
D. S. Akerib, A. K. Al Musalhi, S. K. Alsum +184
Two-phase xenon detectors, such as that at the core of the forthcoming LZ dark matter experiment, use photomultiplier tubes to sense the primary (S1) and secondary (S2) scintillati…
Projected WIMP sensitivity of the LUX-ZEPLIN (LZ) dark matter experiment
D. S. Akerib, C. W. Akerlof, S. K. Alsum +175
LUX-ZEPLIN (LZ) is a next generation dark matter direct detection experiment that will operate 4850 feet underground at the Sanford Underground Research Facility (SURF) in Lead, So…
FlashCam: a fully-digital camera for the medium-sized telescopes of the Cherenkov Telescope Array
G. Pühlhofer, C. Bauer, S. Bernhard +31
The FlashCam group is currently preparing photomultiplier-tube based cameras proposed for the medium-sized telescopes (MST) of the Cherenkov Telescope Array (CTA). The cameras are…
A Global Analysis of Light and Charge Yields in Liquid Xenon
Brian Lenardo, Kareem Kazkaz, Aaron Manalaysay +2
We present an updated model of light and charge yields from nuclear recoils in liquid xenon with a simultaneously constrained parameter set. A global analysis is performed using me…
The Cherenkov Telescope Array Large Size Telescope
G. Ambrosi, Y. Awane, H. Baba +129
The two arrays of the Very High Energy gamma-ray observatory Cherenkov Telescope Array (CTA) will include four Large Size Telescopes (LSTs) each with a 23 m diameter dish and 28 m…
FlashCam: A fully digital camera for the Cherenkov Telescope Array
G. Pühlhofer, C. Bauer, F. Eisenkolb +21
FlashCam is a Cherenkov camera development project centered around a fully digital trigger and readout scheme with smart, digital signal processing, and a "horizontal" architecture…
Response of liquid xenon to Compton electrons down to 1.5 keV
Laura Baudis, Hrvoje Dujmovic, Christopher Geis +5
The response of liquid xenon to low-energy electronic recoils is relevant in the search for dark-matter candidates which interact predominantly with atomic electrons in the medium,…
FlashCam: A fully digital camera for CTA telescopes
G. Pühlhofer, C. Bauer, A. Biland +20
The future Cherenkov Telescope Array (CTA) will consist of several tens of telescopes of different mirror sizes. CTA will provide next generation sensitivity to very high energy ph…
A stacking method to study the gamma-ray emission of source samples based on the co-adding of Fermi LAT count maps
B. Huber, C. Farnier, A. Manalaysay +2
We present a stacking method that makes use of co-added maps of gamma-ray counts produced from data taken with the Fermi Large Area Telescope. Sources with low integrated gamma-ray…
Gator: a low-background counting facility at the Gran Sasso Underground Laboratory
L. Baudis, A. D. Ferella, A. Askin +8
A low-background germanium spectrometer has been installed and is being operated in an ultra-low background shield (the Gator facility) at the Gran Sasso underground laboratory in…
Lowering the low-energy threshold of xenon detectors
P. Sorensen, J. Angle, E. Aprile +34
We show that the energy threshold for nuclear recoils in the XENON10 dark matter search data can be lowered to ~1 keV, by using only the ionization signal. In other words, we make…
Design Concepts for the Cherenkov Telescope Array
The CTA Consortium
Ground-based gamma-ray astronomy has had a major breakthrough with the impressive results obtained using systems of imaging atmospheric Cherenkov telescopes. Ground-based gamma-ray…
Towards an improved understanding of the relative scintillation efficiency of nuclear recoils in liquid xenon
A. Manalaysay
Liquid xenon (LXe) particle detectors are a powerful technology in the field of dark matter direct detection, having shown impressive results in recent years and holding strong pos…
Design and Performance of the XENON10 Dark Matter Experiment
E. Aprile, J. Angle, F. Arneodo +36
XENON10 is the first two-phase xenon time projection chamber (TPC) developed within the XENON dark matter search program. The TPC, with an active liquid xenon (LXe) mass of about 1…
Spatially uniform calibration of a liquid xenon detector at low energies using 83m-Kr
A. Manalaysay, T. Marrodan Undagoitia, A. Askin +8
A difficult task with many particle detectors focusing on interactions below ~100 keV is to perform a calibration in the appropriate energy range that adequately probes all regions…
