AbstractProposal Number: ECS-0741616Proposal Title: SGER: A New Approach to Space Debris ElininationPI Name: Suckewer, SzymonPI Institution: Princeton University ObjectiveThe main objective of this project is to investigate, by computer simulations, the most efficient way to remove small debris and to prepare the basis for a large project on small debris removal in space. Intellectual MeritThe PI will combine computer algorithms currently available at Princeton in order to model the laser beam-debris interaction. The research will concentrate on computer calculations of generation thrust on debris in space by ultra-short and very high intensity laser pulses and long pulses of powerful fiber laser.Broader ImpactsIn 1997 the Project ORION was established by Air Force to assess the possibility of eliminating small size debris ( 10 cm) from space, by shooting a laser beam from the ground at individual debris. Such debris, being "invisible" for navigation devices, may be catastrophic for space vehicles during collision with them. The required laser beam energy was estimated to be in the range of 20 kJ per pulse with extremely low beam divergence (~ 1urad) in order for laser beam to provide adequate intensity on debris at distance ~ 1000 km from the Earth. This project will investigate the use of lasers orbiting in space to eliminate small debris by "kicking them off" of their orbits into lower orbits for the debris to burn up in the atmosphere. It will include research on comparing the efficiency of low energy ultrashort pulse laser and recently developed high power fiber laser for debris elimination. The PI will also investigate the advantages of using lasers located in space in comparison with ground base lasers.

Abstract Propoposal编号：ECS-0741616 PROPOPOSAS标题：SGER：一种新的空间碎片碎片elininationpi名称：Suckewer，Szymonpi Institution：Princeton University Absocevethe该项目的主要目标是通过计算机模拟，是删除小型碎屑和最有效的方法为大型项目的大型项目准备空间中的小型项目的基础。智力优点PI将结合普林斯顿目前可用的计算机算法，以建模激光束束相互作用。这项研究将集中于通过超短和非常高的强度激光脉冲和强大纤维激光的长脉冲在空间中碎屑的计算机计算。距离太空的尺寸碎片（10厘米），通过从单个碎片的地面拍摄激光束。这种碎片是导航设备“无形的”，在与它们发生碰撞时可能会灾难性的太空车辆灾难性。据估计，所需的激光束能在每脉冲的20 kJ范围内，横梁发散极低（〜1URAD），以便激光束在距地球约1000 km处的剩余碎屑提供足够的强度。该项目将调查在太空中轨道上使用激光来消除小碎片，以将它们的轨道“踢开”到低轨道中，以使碎屑在大气中燃烧。它将包括比较低能量超短脉冲激光器效率的研究，并最近开发了用于消除碎屑的高功率纤维激光器。 PI还将调查与地面基础激光器相比，使用位于太空中的激光器的优势。
