We propose two types of neutron-$\gamma_1$-$\gamma_2$ triple coincidence detectors (not constructed) to chase gamma transitions produce p-nuclei following the neutron emission in $(\gamma, n)$ reaction. Neutrons are detected with 24 $^3$He counters embedded a polyethylene moderator Type I detector and 6 liquid scintillation II detector, respectively. $\gamma$ rays high-purity germanium four LaB...

Borexino is a massive calorimetric liquid scintillation detector whose installation has been completed in the underground Gran Sasso Laboratory. The focus of the experiment is on the direct and real time measurement of the flux of neutrinos produced in the 7 Be electron capture reaction in the Sun. Furthermore, recent studies about the reduction of the 11 C background through suitable rejection...

Over the last few decades many techniques have been developed for determination of Sr/Y in the environment. Čerenkov counting technique (developed in the 1960s) is widely used, but can be further developed by the application of emerging technologies. For example, it is believed that the application of the triple-to-double coincidence ratio (TDCR) liquid scintillation counting method can be used...

In this article, we review the possible candidates of dark matter and their proposed properties. We have focused on different methods used for detection such as, search WIMPs at accelerators, indirect direct WIMPs. highlighted detector technologies charge collection after ionization, bubble formation in superheated liquid by particle, scintillation produced due to incident radiation, cryogenic ...

We have developed a new technique that allows the trajectories of ionizing particles to be imaged with very high spatial and temporal resolution. This technique, developed for future experiments in high-energy physics, may also be applied in other fields. Central to the technique is a detector consisting of a bundle of thin, glass capillaries filled with a liquid scintillator of high refractive...

The bright scintillation of pure CsI operated at liquid-nitrogen temperature makes this material a promising dark matter and neutrino detector. We present the first measurement its quenching factor for nuclear recoils. Our findings indicate it is indistinguishable from that sodium-doped room temperature. Additional properties such as light yield, afterglow, decay electron recoils, energy propor...

Abstract Predicted as possible bound states of up, down and strange quarks, strangelets could be more energetically favourable stable than nuclear matter. In this paper we explore the possibility detecting such particles with future large liquid argon detectors developed for neutrino physics. Using signals from ionization scintillation, well measuring range, suggest that a calorimetric TPC dete...

The detection of low energy neutrinos in a large scintillation detector may provide further important information on astrophysical processes as supernova physics, solar physics and elementary particle physics as well as geophysics. In this contribution, a new project for Low Energy Neutrino Astronomy (LENA) consisting of a 50 kt scintillation detector is presented. ∗Corresponding authors. Fax: ...
