Acquisition of Instrumentation for Radiation Hard Optical Electronics Design and Testing

该提案要求为仪器仪表提供资金，用于开发和建造用于发送和接收数字数据的高速、抗辐射光电子元件。该设备将位于南卫理公会大学（SMU）和俄亥俄州立大学（OSU），并将用于设计和建造ATLAS实验的液氩量热计和像素探测器的读出电子设备。ATLAS是位于瑞士日内瓦的欧洲核子研究中心（CERN）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年投入使用时，它将成为世界上首屈一指的粒子物理设备。这一建议的智力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学标准模型中一个尚未被发现的重要成分。ATLAS实验旨在发现希格斯玻色子并详细研究其性质。虽然这些快速，抗辐射的数字数据链路正在为ATLAS开发，但通过光纤的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，并消除了电接地回路。光电子的宽带宽非常适合多路输入通道，并允许引入错误检查和错误恢复传输协议。这些特征在有辐射的情况下尤为重要。在过去的几年中，SMU和OSU的团队都在光电元件的设计和制造方面发展了专业知识。SMU小组设计并构建了用于液氩量热计的快速光学数据链路。OSU小组是设计和测试像素探测器光链路光学电子器件的领先机构，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辐射硬版本。所要求的设备将使这些小组能够扩大它们在光电子学方面的专门知识，并加强它们现在和将来对ATLAS实验的贡献。这项建议的广泛影响包括加强新大和俄勒冈州立大学的基础设施；振奋人心，吸引新一代科学家；开发HEP以外的应用技术和电子产品；向科学界和商界传播从本项目中学到的信息，并为社会提供一个跨越地理和文化界限的合作范例。

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.
