The next generation of bolometric experiments searching for rave events, in particular the neutrino-less double beta decay, needs fast, high-sensitivity and easy-to-scale cryogenic light detectors. CALDER project (2014-2020) developed a new technology detection at temperature. In this paper we describe achievements final prototype project, consisting $5\times5$ cm$^2$, 650 $\mu$m thick silicon ...

Abstract The combination of a high speed two-dimensional neutron detector and an intensive pulsed source provides not only transmission imaging but also information on crystal structures, orientations constituent elements by analyzing spectra. delay-line current-biased kinetic-inductance (CB-KID) is superconducting with spatial temporal resolutions, multi-hit tolerance. We demonstrated that the...

We present a design for superconducting nanowire binary shift register, which stores digital states in the form of circulating supercurrents high-kinetic-inductance loops. Adjacent loops are connected with nanocryotrons, three terminal electrothermal switches, and fed an alternating two-phase clock to synchronously transfer state between A two-loop serial-input register was fabricated thin-film...

We propose a design theory of the miniaturized high temperature superconducting (HTS) coplanar waveguide (CPW) bandpass filter (BPF), which is composed of meanderline quarter-wavelength resonator, Jand K-inverters. The Jand K-inverters are realized by using interdigital gap and meander-shape inductor. To evaluate the kinetic inductance of the K-inverter, we fabricate the YBCO resonator connecte...

The nonlinear response associated with the current dependence of superconducting kinetic inductance was studied in capacitively shunted NbTiN microstrip transmission lines. It found that per unit length one line could be changed by up to 20% applying a DC current, corresponding single pass time delay 0.7 ns. To investigate dissipation, Bragg reflectors were placed on either end section this typ...

A coplanar waveguide resonator (CPR) is presented for kinetic inductance (Lk) and penetration depth (λL) measurements of superconducting boron doped nanocrystalline diamond (B-NCD) at microwave frequencies 0.4 to 1.2 GHz temperatures below 3 K. Using finite element modelling experimental measurements, this work demonstrates that thin granular B-NCD films (thickness d≈ 500 nm) on Si have a large...

SuperSpec is a novel on-chip spectrometer we are developing for multi-object, moderate resolution (R = 100− 500), large bandwidth (∼1.65:1) submillimeter and millimeter survey spectroscopy of high-redshift galaxies. The spectrometer employs a filter bank architecture, and consists of a series of half-wave resonators formed by lithographically-patterned superconducting transmission lines. The si...
