发射空间实验PAMELA
Launch of the Space experiment PAMELA
摘要：
PAMELA是一个卫星携带的实验，旨在以很高的精度研究银河系、太阳系和被困自然界的宇宙射线，能量范围很广：质子：80 MeV-700 GeV，电子：50 MeV-400 GeV。主要目标是研究反物质的组成部分：反质子（80 MeV-190 GeV）、正电子（50 MeV-270 GeV），并以10^-8的精度寻找反物质。该实验安装在俄罗斯Resurs-DK 1卫星上，于2006年6月15日发射，轨道为350*600公里，倾角为70度。探测器由一系列闪烁体计数器组成，这些计数器布置在永磁体光谱仪的末端，以提供电荷、飞行时间和刚度信息。轻子/强子的识别是由一个硅钨量能器和一个中子探测器放置在设备的底部。反计数器系统离线使用，以拒绝来自卫星的错误触发。在自触发模式下，量热计、中子探测器和簇射尾部捕捉器能够独立测量高达2 TeV的轻子分量。在这项工作中，我们描述了实验，其科学目标和性能在发射后的头几个月。
英文摘要：
PAMELA is a satellite borne experiment designed to study with great accuracy cosmic rays of galactic, solar, and trapped nature in a wide energy range protons: 80 MeV-700 GeV, electrons 50 MeV-400 GeV). Main objective is the study of the antimatter component: antiprotons (80 MeV-190 GeV), positrons (50 MeV-270 GeV) and search for antimatter with a precision of the order of 10^-8). The experiment, housed on board the Russian Resurs-DK1 satellite, was launched on June, 15, 2006 in a 350*600 km orbit with an inclination of 70 degrees. The detector is composed of a series of scintillator counters arranged at the extremities of a permanent magnet spectrometer to provide charge, Time-of-Flight and rigidity information. Lepton/hadron identification is performed by a Silicon-Tungsten calorimeter and a Neutron detector placed at the bottom of the device. An Anticounter system is used offline to reject false triggers coming from the satellite. In self-trigger mode the Calorimeter, the neutron detector and a shower tail catcher are capable of an independent measure of the lepton component up to 2 TeV. In this work we describe the experiment, its scientific objectives and the performance in the first months after launch.
