Calibration electronics for the 30 and 40 GHz instrument (TFGI) of the QUIJOTE experiment
Jorge Luis Díaz-Acosta, Roger John Hoyland, Francisco Javier Casas +1
The 30 and 40 GHz instruments of the QUIJOTE radio astronomy experiment use very sensitive receivers which need to be characterized both to ensure their proper functioning and for…
The DALI Haloscope: A Magnetized Phased Array Coupled to a Semi-Open Fabry--Pérot Resonator
Javier De Miguel, Antonios Gardikiotis, Eduardo David González-Carretero +10
DALI is an axion haloscope consisting of a magnetized phased array backed by a conducting mirror and coupled in the near field to a semi-open Fabry--Pérot resonator. The applied st…
Constraints on Galactic Dark Photons from a DALI Prototype
Javier De Miguel, Antonios Gardikiotis, Elvio Hernández-Suárez +10
An analysis of 36 hours of data from a DALI haloscope reveals no statistically significant excess attributable to dark-photon dark matter. We therefore set new constraints in the 6…
A high-isolation wideband channelizer for MKID readouts: a custom HLS implementation on RFSoC
Alberto Hernandez Fernandez, David Diaz Martin, Jose Javier Diaz Garcia +4
We present a high-performance channelizer for Microwave Kinetic Inductance Detectors (MKIDs), designed to mitigate spectral leakage and scalloping loss through a 50% overlapping po…
First limits on axion dark matter from a DALI prototype
Javier De Miguel, Enrique Joven, Elvio Hernández-Suárez +13
We report a pilot dark matter search with a cryogenic, magnetized, scaled-down DALI prototype. An analysis of 36 hours of data reveals no statistically significant excess attributa…
Systematic errors in spectral measurements with the Tenerife Microwave Spectrometer
A. M. Arriero-Lopez, J. A. Rubiño-Martín, F. Cuttaia +2
We present an analytical instrument model of the TMS radiometer, a pseudo-correlation system designed for absolute sky-temperature measurements through a continuous comparison betw…
