Background: The established GADGET detection system, designed for measuring weak, low-energy $\beta$-delayed proton decays, features a gaseous Proton Detector with MICROMEGAS readout for calorimetric particle detection, surrounded by a Segmented Germanium Array for high-resolution prompt $\gamma$-ray detection. Purpose: To upgrade GADGET's Proton Detector to operate as a compact Time Projection Chamber (TPC) for the detection, 3D imaging and identification of low-energy $\beta$-delayed single- and multi-particle emissions mainly of interest to astrophysical studies.

Evidence of a near-threshold resonance in $^{11}$B relevant to the $\beta$-delayed proton emission of $^{11}$Be
/ Ayyad, Y. (Santiago de Compostela U., IGFAE ; Michigan State U., East Lansing (main)) ; Mittig, W. (Michigan State U. ; Michigan State U., East Lansing (main)) ; Tang, T. (Michigan State U., East Lansing (main)) ; Olaizola, B. (CERN) ; Potel, G. (LLNL, Livermore) ; Rijal, N. (Michigan State U., East Lansing (main)) ; Watwood, N.

(Santiago de Compostela U., IGFAE) et al.
A narrow near-threshold proton-emitting resonance (Ex = 11.4 MeV, J$^{\pi}$ = 1/2$^{+}$ and $\Gamma_{p}$ = 4.4 keV) was directly observed in $^{11}$B via proton resonance scattering. This resonance was previously inferred in the $\beta$-delayed proton emission of the neutron halo nucleus $^{11}$Be. [...]

Two-proton decay of the unbound $ T_{z} =-2$ nucleus$^{16}$Ne , produced in one-neutron knockout from a 500 MeV/u$^{17}$Ne beam, has been studied at GSI. The ground state, at a resonance energy 1.388(15) MeV, ( $ \Gamma =0.082(15)$ MeV) above the$^{14}$O +p+p threshold, and two narrow resonances at $ E_{r} =3.220(46)$ MeV and 7.57(6) MeV have been investigated.

Nuclear astrophysics with radioactive ions at FAIR
/ Reifarth, R. ; Altstadt, S. ; Göbel, K. ; Heftrich, T. ; Heil, M. ; Koloczek, A. ; Langer, C. ; Plag, R. ; Pohl, M. ; Sonnabend, K. et al.
The nucleosynthesis of elements beyond iron is dominated by neutron captures in the s and r processes. However, 32 stable, proton-rich isotopes cannot be formed during those processes, because they are shielded from the s-process flow and r-process beta-decay chains. [...]
