This proposal requests funds for instrumentation to be used for the development and construction of high speed, radiation resistant opto-electronics components for use in transmitting and receiving digital data. The equipment will be located at the Southern Methodist University (SMU) and at The Ohio State University (OSU) and will be used for the design and construction of readout electronics for the ATLAS experiment's liquid argon calorimeter and pixel detector. . ATLAS is one of two large-scale detectors being constructed for the Large Hadron Collider (LHC) at the CERN laboratory in Geneva, Switzerland. When the LHC turns on in 2007, it will be the premier particle physics facility in the world. The intellectual merit of this proposal is the advancement of our understanding of the laws of nature. The Higgs boson is the one essential ingredient in the standard model of particle physics that has yet to be discovered. The ATLAS experiment is designed both to discover the Higgs boson and to study its properties in detail. While these fast, radiation resistant digital data links are being developed for ATLAS, fast data transfer via optical fibers has many applications. In high-energy physics experiments, it substantially reduces the volume of cables thereby freeing up valuable space as well as removing electrical ground loops. The wide bandwidth of opto-electronics is well suited for multiplexing input channels and allows for the introduction of error checking and error recovery transmission protocols. These features are especially important in the presence of radiation. Over the past several years, both the SMU and OSU groups have developed expertise in the design and fabrication of opto-electronics components. The SMU group has designed and constructed fast optical data links for the liquid argon calorimeter. The OSU group is the lead institution in the design and testing of the optical electronics for the pixel detector optical link and has developed radiation hard versions of the Digital Opto-Receiver Integrated Circuit and the Vertical Cavity Surface Emitting Lasers driver circuit. The equipment requested will allow the groups to broaden their expertise in opto-electronics as well as to strengthen their present and future contributions to the ATLAS experiment. Among the broader impacts of this proposal are enhancing the infrastructure of the SMU and OSU groups; exciting and attracting a new generation of scientists; developing techniques and electronics that have applications beyond HEP; disseminating the information learned in this project to the scientific and business community, and providing an example to society of a collaborative effort that crosses geographic and cultural boundaries.

该提案要求为用于开发和建造用于发送和接收数字数据的高速、防辐射光电子元件的仪器设备提供资金。该设备将安装在南卫理公会大学(SMU)和俄亥俄州立大学(OSU)，并将用于设计和建造ATLAS实验的液体氩热量计和像素探测器的读出电子设备。。阿特拉斯是位于瑞士日内瓦的欧洲核子研究组织实验室正在为大型强子对撞机(LHC)建造的两个大型探测器之一。当大型强子对撞机在2007年启动时，它将成为世界上首屈一指的粒子物理设施。这一建议的学术价值在于促进了我们对自然规律的理解。希格斯玻色子是粒子物理标准模型中尚未被发现的一个重要组成部分。ATLAS实验既是为了发现希格斯玻色子，也是为了详细研究它的性质。虽然这些快速、抗辐射的数字数据链路是为ATLAS开发的，但通过光纤进行快速数据传输有许多应用。在高能物理实验中，它大大减少了电缆的体积，从而释放了宝贵的空间，并消除了电气接地回路。光电子学的宽带宽非常适合于多路复用输入通道，并允许引入差错检查和差错恢复传输协议。这些特征在辐射存在的情况下尤其重要。在过去的几年里，SMU和OSU小组都在光电子元件的设计和制造方面发展了专业知识。SMU小组已经为液体氩热量计设计和建造了快速光学数据链路。OSU集团在像素探测器光链路的光电子设计和测试方面是领先的机构，并开发了数字光接收器集成电路和垂直腔面发射激光器驱动电路的抗辐射版本。所要求的设备将使这些小组能够扩大他们在光电子学方面的专门知识，并加强他们目前和未来对ATLAS实验的贡献。这项提议的更广泛影响包括加强SMU和OSU小组的基础设施；激励和吸引新一代科学家；开发具有超越HEP的应用的技术和电子产品；向科学界和企业界传播从该项目中学到的信息，并向社会提供跨越地理和文化界限的合作努力的榜样。
