Patras 2022 - 44 - Le Hoang Nguyen - Radiometric broadband searches for light darkmatter (BRASS-p)

Le Hoang Nguyen from the University of Hamburg, Germany, talks about "Radiometric broadband searches for light dark matter with BRASS-p" at the 17th Patras Workshop on Axions, WIMPs and WISPs.
The Patras Workshop took place at the Johannes Gutenberg University of Mainz as the second week of events within the Wavy Dark Matter Summer event series in August 2022. www.wavydarkmatter.org
Abstract:
Broadband Radiometric Axion SearcheS (BRASS) is the haloscope
experimental framework that can be employed to search for the
axion/ALPs and hidden photons by employing novel experimental
approaches and synergies with state-of-the-art broadband techniques
developed in radio astronomy. The prototype, BRASS-p - developed
at the University of Hamburg, is a broadband detector that
searches for light dark matter signal in the frequency range of 12-18
GHz. This talk will discuss the setup and calibration of BRASS-p,
which comprises the conversion panel, parabolic mirror, cryogenic
broadband receiver, and digital backend system. We present our signal
scan routine of the first science run targeting the hidden photon
dark matter within 12-18 GHz, and discuss the preliminary result
from the first science run.
