We describe the design and properties of a multi-mode detector system for photon detection at mm wavelengths. We modeled its basic elements (absorber, integrating cavity, waveguide and horn antenna) through numerical simulations, and built a prototype single-pixel system for performance validation. Following a successful verification of the...

In this paper, we explore the possibility of using transition edge sensor (TES) detectors in multi-mode configuration in the focal plane of the Short Wavelength Instrument for the Polarization Explorer (SWIPE) of the balloon-borne polarimeter Large-Scale Polarization Explorer (LSPE) for the Cosmic Microwave Background (CMB) polarization. This...

Large area spiderweb bolometers of 8 mm diameter and a mesh size of 250 Î1/4m are fabricated in order to couple with approximately the first 20 modes of a multimode EM cavity at about 140 GHz. The sensor is a Ti/Au/Ti 3 layer TES with Tc tuned in the 330-380 mK and 2 mK transition width. We describe the detector design and the fabrication...

We present a concept for the payload SAGACE, the Spectroscopic Active Galaxies And Cluster Explorer, devoted to study the evolution of Universe structures using different observables, all of them in the rmn/submm wavelength. The SAGACE payload is made of a passively cooled 3m telescope, a cryogenic Fourier Transform Spectrometer (FTS) and...
