  • A scintillating fiber sampling calorimeter telescope (SSCT (SF)) is proposed which is to be operated on board a satellite for the observation of cosmic gamma rays ranging from 200 MeV to 200 GeV. The idea of SSCT (SF) is based on the experience in developing a Si(Li)/Pb sampling calorimeter telescope (SSCT (Si)); SSCT(SF) replaces the Si detectors in SSCT(Si) by scintillating fibers. Some key parameters of SSCT(Si) are: the active area is 2,500 cm{sup 2}, effective area 1,500 cm{sup 2}, the median angular reoslution 1.6{degree} at 1 GeV, 0.34{degree} at 10 GeV, 0.21{degree} at 30 GeV, and the r.m.s energymore » resolution is 20, 17 and 18% at 1, 10 and 100 GeV, respectively. If a thicker calorimeter is used, 17%/{radical}{ital E}(GeV) is possible. SSCT(SF) is now under development. From a preliminary test, we expect that the angular resolution of SSCT(SF) is, at worst, almost the same as SSCT(Si), and the energy resolution could be better than 30% at 1 GeV. Probably almost the same energy resolution is obtainable. An effective area of one order of magnitude larger than the EGRET can be attained with a low cost.« less
  • The GRANDE experiment is a ''next-generation'' detector capable of making significant contributions to the fields of neutrino and ..gamma..-ray astrophysics as well as performing important ''conventional'' high-energy physics investigations. The detector, which covers an area of 250 m /times/ 250 m, will have excellent coverage for potential sources of ..nu.. emission in the southern hemisphere and of VHE and UHE sources in the northern hemisphere. For VHE and UHE showers, the low threshold (10 TeV) and complete coverage for all three shower components (electromagnetic, muonic, and hadronic) are unique. Excellent angular resolution, less than or equal to1/degree/ for ..nu..'s andmore » less than or equal to.3/degree/ for ..gamma..-rays, large acceptance, good energy resolution, and wide energy sensitivity will permit detailed studies of the observed signals enabling a quantitative confrontation with theoretical predictions. The detector and its capabilities will be described. 5 refs., 3 figs., 2 tabs.« less
