Abstract
The main goal of the balloon-borne "PULSAR" experiment is to observe ray photons of variable sources and pulsars in the energy range 0.1-5.0 MeV. The geometrical arrangement of the telescope has been designed according to detector sensitivity estimations for the pulsed radiation, which are carried out by empirical and analytical methods. From the obtained results we expect to achieve a detection sensitivity of 3.7 X 10^-7 photons 1 (0.1 - 0.5 MeV) and 4.5 X 10^-8 photons cm-2 s- 1 keV-1 (1.0 - 5.0 MeV), in 5 hours integration time at 5 g cm- atmospheric depth, with 3σ statistical significance. On-board electronics was developed compatible with the available telemetry capacity, able to process the data with a time resolution of ∼ 4 milliseconds.
