A cryogenic apparatus with a rotatable substrate for matrix isolation spectroscopy of BaF in neon crystals down to 3.2 K
Alessandro Lippi, Diego Bisero, Caterina Braggio +7
We present a new experimental apparatus for matrix isolation spectroscopy capable of growing cryogenic crystal matrices doped with barium monofluoride (BaF), a candidate for measur…
Neutral Barium in Solid Neon: Optical Spectroscopy and First Excited State Lifetime
Alessandro Lippi, Giovanni Carugno, Roberto Calabrese +5
Matrix isolation spectroscopy enables probing atomic properties in controlled cryogenic environments. We present a spectroscopic study on neutral barium atoms embedded in a neon cr…
Cascade Superfluorescence in Er:YLF
Federico Chiossi, Caterina Braggio, Alen Khanbekyan +7
We report the analysis of paired photon pulses arising from two cascading transitions in continuously pumped Erbium-doped YLiF 1% and 0.01% crystals at 1.6 K. The dependence of…
Spontaneous formation of a macroscopically extended coherent state
C. Braggio, F. Chiossi, G. Carugno +2
It is a straightforward result of electromagnetism that dipole oscillators radiate more strongly when they are synchronized, and that if there are dipoles, the overall emitted…
GaAs as a bright cryogenic scintillator for the direct dark matter detection
S. Vasiukov, F. Chiossi, C. Braggio +4
The optical and scintillation properties of undoped, Si-doped, and Si, B co-doped GaAs samples were studied. The light yield specification and X-ray luminescence of GaAs over a wid…
Infrared and visible scintillation of Ho-doped YAG and YLF crystals
F. Chiossi, A. F. Borghesani, G. Carugno
In our effort to develop a new kind of detector for low-energy, low-rate energy deposition events we have investigated the cathodo- and radioluminescence of Ho:YAG and Ho:YLF singl…
Laser induced fluorescence for axion dark matter detection: a feasibility study in YLiF:Er
C. Braggio, G. Carugno, F. Chiossi +8
We present a detection scheme to search for QCD axion dark matter, that is based on a direct interaction between axions and electrons explicitly predicted by DFSZ axion models. The…
Cathodo- and radioluminescence of Tm:YAG and Nd:YAG in an extended wavelength range
A. F. Borghesani, C. Braggio, G. Carugno +2
We have studied the cathodo- and radioluminescence of Nd:YAG and of Tm:YAG single crystals in an extended wavelength range up to m in view of developing a new kind of…
A new technique for infrared scintillation measurements
F. Chiossi, K. Brylew, A. F. Borghesani +4
We propose a new technique to measure the infrared scintillation light yield of rare earth (RE) doped crystals by comparing it to near UV-visible scintillation of a calibrated Pr:(…
Particle detection through the quantum counter concept in YAG:Er
A. F. Borghesani, C. Braggio, G. Carugno +5
We report about a novel scheme for particle detection based on the infrared quantum counter concept. Its operation consists of a two-step excitation process of a four level system,…
