   The characterization of a hybrid telescope detector for low energy alpha detection

   Rajkumar Santra🇮🇳 · Subinit Roy🇮🇳

   Characterization of a hybrid $telescope$ with gas transmission detector ($\Delta$E) and a solid-state stop detector (E) has been fabricated for detection of low energy $\alpha$ particles between 5 to 1 MeV. The detector is developed for utilization in the study of alpha excitation function in (p.$\alpha$) reaction. The gas ionization chamber, operated in axial field mode, measures the differential energy loss ($\Delta$E), while the residual energies are measured by silicon detector. Particle identification is realized by implementing the $\Delta$E-E technique. The optimum sensitivity of the detector as a telescope has been studied down to the lowest energy value of 0.89 MeV $\alpha$-particles with a suitable combination of electric field and pressure or E/p value in the ionization region.
