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…

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…
