In this talk I will review different types of Active Target detectors and their application to various experimental situations. Although Active Target detectors have clear advantages from the points of view of luminosity and angular coverage, their optimization to particular experimental goals often require different configurations. Several of the parameters that can be considered will be covered ... More

Active targets are very versatile instruments. On some aspects, like the luminosity of a reaction measurement, they have a clear advantage over more traditional setups. In other areas, sometimes a compromise has to be chosen in order to obtain usable information on various parameters such as energy, channel and particle identification. The use of auxiliary detectors and techniques can help improv ... More

Classical novae and type I x-ray bursts are explosive events that occur in close binary systems where hydrogen-rich material is accreted on the surface of a compact object. This accreted material is heated and compressed until a thermonuclear runaway occurs. During this explosion heavier nuclei are produced via proton captures and beta decays. In many proton capture reactions, resonant cap ... More

The development of an Optical Time Projection Chamber (OTPC) at the University of Warsaw about a decade ago opened the possibility to investigate a broad range of rare decay modes with very high sensitivity.

The isotopes within the limiting lines of bound nuclei (or drip-lines) are goals of exploration for as many elements as possible. However the drip-line is not the end of the nuclear existence, and nuclei beyond the proton and neutron drip-lines may live much longer than the characteristic time of an orbital motion of nucleons in nuclei. These nuclei called resonances have lifetimes determined by t ... More

During the commissioning of the prototype AstroBox1 detector at TAMU [1], it was noticed that a gas detector with Micro Pattern Gas Amplifiers (MPGAD) [2] had two applications. First, such a detector was useful for detecting low-energy protons ( < 1 MeV) from beta-delayed proton decay because the energy deposit of the beta-particles in the gas was small and the signal from the proton energy loss i ...
