Title: FInal Technical Repot of the Project: Design and Implementation of Low-Power 10Gb/s/channel Laser/Silicon Photonics Modulator Drivers with SEU Tolerance for HL-LHC

Abstract

During the funding period of this award from May 1, 2014 through March 30, 2016, we have accomplished the design, implementation and measurement results of two laser driver chips: LpGBLD10+ which is a low-power single-channel 10Gb/s laser driver IC, and LDQ10P, which is a 4x10Gb/s driver array chip for High Energy Physics (HEP) applications. With new circuit techniques, the driver consumes a record-low power consumption, 31 mW @10Gb/s/channel and occupies a small area of 400 µm × 1750 µm for the single-channel driver IC and 1900umx1700um for the LDQ10P chip. These characteristics allow for both the LpGBLD10+ ICs and LDQ10P suitable candidate for the Versatile Link PLUS (VL+) project, offering flexibility in configuring multiple Transmitters and receivers.

  • A series of experiments was performed to test the dependence of superadient power generated by stimulated Raman backscattering (at 2 mm wavelength) upon ripple-field amplitude and length. Experiments were also performed to understand the possibility of using distributed feedback in a collective mode free electron laser. A theoretical study was completed to understand the growth of circular waveguide modes by parametric coupling to cold beam waves, with field gradients included. This is similar to free electron laser configurations to be studied in upcoming experiments.
  • A plan for engineering evaluation of steam vs. electric drivers is presented. The plan involves 3 levels of in-plant steam generation, the use of steam to drive the maximum possible number of pieces of major equipment, use of waste heat and, in some cases, coal-fired boilers and superheaters, to provide additional steam and electric power. At the lowest level of steam generation, imported electric power drives some major equipment and all minor equipment; at the intermediate level steam drives the maximum possible number of pieces of major equipment and electric power is imported for the minor equipment; at the highestmore » level of steam generation, no power is imported and electric power is generated for the minor equipment, lights, etc. (LTN)« less
  • A test facility has been constructed to test high power ignitrons using an electrolytic bank. The goal of this project, which was named Hercules (High Energy Research Concerning the Ultimate Lifetime of Experimental Switches), was to test the lifetime and switching characteristics of high power ignitrons for Lawrence Livermore`s laser upgrade program. The main tubes of interest that have been tested were the NL-9000A from Richardson Electronics, and the BK-1002 from English Electric Valve (EEV). Both tubes have stainless steel, cup style anodes. Both tubes were connected in series for the tests. Required test parameters were Ipeak = 300 kA,more » and Qtransfer = 200 C. During the tests, the BK-1002 tube failed due to ignitor shorting. The average forward voltage drop across the EEV tube was almost twice than the drop across the NL-9000A. After the tube failure, the BK-1002 was replaced by a NL-1057 to continue testing of the NL-9000A.« less
  • The Carolina Power and Light Company Rate Demonstration Project was conducted to observe the effects of time-of-use electricity rates on household electricity consumption. Under time-of-use (TOU) rates higher prices are charged for electricity used during those times when demand and system costs are higher; and lower prices, when demand and system costs are lower. In this project 514 residential customers were placed on a number of seasonal time-of-use electricity rates for periods of 14 to 18 months starting October 1977 and February 1978 and ending in May 1979.
  • Research on ways to organize a body of numerical procedures in such a way that they may be invoked automatically by processes which accept symbolic and algebraic specifications from a user, and produce combined symbolic, numeric and graphical output is described. Efforts are made to make these algebraic systems as flexible and useful as possible in this context, and to integrate them successfully into a man-machine design which provides operating system, language, and algorithm support. Various aspects of this research are reviewed including languages for symbolic algebra systems, programming environments, numerical software, numeric/symbolic programs, floating point hardware, elementary functions, Macsymamore » distribution, VAX/Macsyma/computer architecture, interactive systems, Lisp language, and advanced computer concepts (supercomputers). The computing environment for this research are UNIX-VAX-11/780, Vax 11/750, and Motorola 68000 systems. 32 refs. (DWL)« less
