Improvement and assessment of the radiopurity of Micromegas readout planes

Juan Castel, Susana Cebrian, Theopisti Dafni +17

Micromesh Gas Structures (Micromegas) as readout of gaseous Time Projection Chambers (TPCs) are being considered in experiments investigating rare phenomena, like the nuclear doubl…

Low-energy threshold demonstration for dark matter searches in TREX-DM with an Ar source produced at CNA HiSPANoS

J. Castel, S. Cebrián, T. Dafni +16

We report on the successful implementation of an Ar calibration source in the TREX-DM detector, a high-pressure time projection chamber designed for low-mass dark matter sea…

Efficient cosmic ray generator for particle detector simulations

David Díez Ibáñez, Luis Obis Aparicio

Traditional cosmic ray simulations make use of the Montecarlo method in a very naive way to randomise energy and direction for each simulated particle. The flux of cosmic rays is m…

Spatial resolution studies with the BabyIAXO Micromegas prototype

A. Quintana, J. Castel, S. Cebrián +20

The spatial resolution of the Micromegas prototype developed for the BabyIAXO experiment was evaluated using a low-energy X-ray beam at the SOLEIL synchrotron facility. BabyIAXO, c…

Search for solar axions produced through the axion-electron coupling using a new GridPix detector at CAST

K. Altenmüller, V. Anastassopoulos, S. Arguedas-Cuendis +61

We present a search for solar axions produced through the axion-electron coupling using data from a novel 7-GridPix detector installed at the CERN Axion Solar Telescope…

Daily modulations and broadband strategy in axion searches. An application with CAST-CAPP detector

F. Caspers, C. M. Adair, K. Altenmüller +60

It has been previously advocated that the presence of the daily and annual modulations of the axion flux on the Earth's surface may dramatically change the strategy of the axion se…
