Description
Determining the ratio of carbon-to-oxygen produced at the end of the helium burning in stars is a paramount importance problem for nuclear astrophysics. In recent years, the advent of high-intensity $\gamma$-ray beams opened a new opportunity to study the $^{12}$C($\alpha$,$\gamma$)$^{16}$O reaction regulating the ration by investigating the time-reversal photodisintegration reaction.
To take advantage of this approach an active-target Time Projection Chamber with electronic readout is being developed at the University of Warsaw, Poland. The $^{16}$O($\alpha$,$\gamma$)$^{12}$C reaction will be studied in an experiment with the gamma-ray beam provided by the High Intensity Gamma-Ray Source (HI$\gamma$S), USA, and in Day-1 experiments at the Extreme Light Infrastructure Nuclear Physics (ELI-NP), Romania.
During the presentation, I will discuss the challenges we have faced and the solutions we adopted for detector design. I will also outline the present problems and plans for future.
