A Study of Point Source and Acceleration Mechanism.

为了研究主要宇宙射线组成，点核交互的高能伽马射线和特征特征的来源，一个新的扩展式空气淋浴阵列在印度南部奥蒂的构造下，在2，200米以上的备选案文s·l.这个空气淋浴阵列包含约1，1000个塑料清洗机（1 m ^2每个区域）将覆盖300 m * 300 m在一个区域和4个单元的Muon探测器（each unit consists of 36 m ^2*4 in area） to be covered 564 m ^2 in area at the central region of above EAS array。这些单元检测器考虑了4层在正态条件下的比例计数器，并且单元的能量通过垂直传递-0.6 GeV.这个EAS阵列承诺我们能够建立一个具有-10^<16>eV的能量，并通过测量电子和单元之间的两个横向密度分布的能量来建立一个完整的主组成。在添加到这一点上，我们还可以衡量由各种能源组发起的展示者的多重分布。From the comparison of Monte Carlo simulations concerning the detection efficiencey and expected event rate classified by primary composition gives us very accurate information concerning the primary composition.Huge muon detector gives us very clear cut to identify between primary gamma-ray and nuclear compositions。在增加到进一步考虑EAS的发展时，我们可以选择伽马射线引物。从EAS和伽马射线的两个精确确定到达方向，如果伽马射线来源存在，我们可以识别它们。

To study primary cosmic ray composition, point source of high energy gamma-ray and characteristic feature of nuclear interactions, a new extesive air shower array is under construction at Ooty in southern India, at an altitude of 2,200m above s・l.This air shower array contains about 1,000 plastic scintillators (area 1m^2 each) to be covered 300m*300m in area and 4 units of muon detectors (each unit consists of 36m^2*4 in area) to be covered 564m^2 in area at the central region of above EAS array. These muon detector consist of 4 layrs of proportional counters in orthogonal conditions, and energy of muons to be passed through in verticalis-0.6GeV.This EAS array promise us to be able to establish primary composition upto energy of -10^<16> eV and give clear identification of parent particles by measuring both lateral density distribution of electons and muons. In addition to this, we can also measure the multiplicity distribution for showers initiated by primaries of various energy groups. From the comparison of Monte Carlo simulations concerning the detection efficiencey and expected event rate classified by primary composition gives us very accurate information concerning the primary composition.Huge muon detector gives us very clear cut to identify between primary gamma-ray and nuclear compositions. In addition to the above considering development of EAS,we can select gamma-ray primaries. From both accurate determination ofarrival direction of EAS and gamma-rays, if gamma-ray sources exist, we can be identified for them.
