SRF materials such as niobium have been extremely useful for accelerator technology but require low temperatures operation < 9 K. The development of high temperature superconductors (HTS) is promising due to their to their high critical temperature 89.5 K. [...]

Daily modulations and broadband strategy in axion searches: An application with the CAST-CAPP detector
/ Caspers, F. (ESI, Archamps ; CERN) ; Adair, C.M. (British Columbia U.) ; Altenmüller, K. (Zaragoza U.) ; Anastassopoulos, V. (Patras U.) ; Cuendis, S. Arguedas (CERN) ; Baier, J. (Freiburg U.) ; Barth, K. (CERN) ; Belov, A. (Unlisted) ; Bozicevic, D. (Rijeka U.) ; Bräuninger, H. (Garching, Max Planck Inst., MPE) et al.
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 searches. The arguments were based on the so-called Axion Quark Nugget (AQN) dark matter model which was originally put forward to explain the similarity of the dark and visible cosmological matter densities $\Omega_{\rm dark}\sim \Omega_{\rm visible}$. [...]

We describe the results of a haloscope axion search performed with an 11.7 T dipole magnet at CERN. The search used a custom-made radio-frequency cavity coated with high-temperature superconducting tape. [...]

A Proposal for a Low-Frequency Axion Search in the 1–2 μ$\umu$ eV Range and Below with the BabyIAXO Magnet
/ Ahyoune, Saiyd (ICC, Barcelona U.) ; Melcón, Alejandro Álvarez (Cartagena Politecnica U.) ; Cuendis, Sergio Arguedas (ICC, Barcelona U.) ; Calatroni, Sergio (CERN) ; Cogollos, Cristian (Munich, Max Planck Inst.) ; Devlin, Jack (Imperial Coll., London) ; Díaz-Morcillo, Alejandro (Cartagena Politecnica U.) ; Díez-Ibáñez, David (U. Zaragoza (main)) ; Döbrich, Babette (Munich, Max Planck Inst.) ; Galindo, Javier (U. Zaragoza (main)) et al.
In the near future BabyIAXO will be the most powerful axion helioscope, relying on a custom-made magnet of two bores of 70 cm diameter and 10 m long, with a total available magnetic volume of more than 7 m$^3$. In this document, we propose and describe the implementation of low-frequency axion haloscope setups suitable for operation inside the BabyIAXO magnet. [...]

Search for dark matter axions with CAST-CAPP
/ Adair, C.M. (British Columbia U.) ; Altenmüller, K. (Zaragoza U.) ; Anastassopoulos, V. (Patras U.) ; Cuendis, S. Arguedas (CERN) ; Baier, J. (Freiburg U.) ; Barth, K. (CERN) ; Belov, A. (Moscow, INR) ; Bozicevic, D. (Rijeka U.) ; Bräuninger, H. (Garching, Max Planck Inst., MPE) ; Cantatore, G. (INFN, Trieste ; Trieste U.) et al.
The CAST-CAPP axion haloscope, operating at CERN inside the CAST dipole magnet, has searched for axions in the 19.74 $\mu$eV to 22.47 $\mu$eV mass range. The detection concept follows the Sikivie haloscope principle, where Dark Matter axions convert into photons within a resonator immersed in a magnetic field. [...]

Study on transient heat transfer at metal to dielectric interfaces in the temperature range between 3.5 K and 30 K
/ Koettig, T (CERN) ; Golm, J (CERN) ; Liberadzka, J (CERN) ; Borges de Sousa, P (CERN) ; Bremer, J (CERN)
The thermal conductivity and diffusivity across a combination of metallic and
insulating layers are important thermodynamic input parameters for cooling studies of composite
materials or assemblies built out of layers of different electrical and thermal conductivity. The
dynamic response of such thermal contacts across electrically insulating layers can be expressed
in terms of a diffusivity-like value, which is giving insight on the interface thermal resistance. [...]

Heat transfer at dielectric - metallic interfaces in the ultra-low temperature range
/ Liberadzka, J (CERN ; Twente U., Enschede) ; Golm, J (CERN) ; Koettig, T (CERN) ; Bremer, J (CERN) ; ter Brake, H J M (Twente U., Enschede)
In the framework of the AEgIS project a series of steady state and dynamic
heat transfer measurements at ultra-low temperatures was conducted in the Central Cryogenic
Laboratory at CERN. Two sandwich setups, simulating the behaviour of ultra-cold AEgIS
electrodes, were investigated and compared, namely: a sapphire − indium − copper and a
sapphire − titanium − gold − indium − copper sandwich. [...]
