  1. Instrumentation Division Seminar

    2:30 pm, Large Conference Room, Bldg. 535

    Moving towards continuous data readout and transmission in the future Phase-II upgrade of the LAr Calorimeter creates a few technical challenges for the front-end electronics design as well as the back-end signal-processing needs. Particularly, the elevated pileup corruption to the data samples at an unprecedented luminosity level dictates a revision of the linear optimal filtering (LOF) approach currently deployed in the ATLAS experiment. In addition, the analog front-end (AFE) architecture needs to be revisited for supporting an ultra-high dynamic range (16-18 bits), in anticipation of any potential future evolution to a highly integrated, low cost implementation platform or technology for further power and cost reductions. In this talk, a few topics along these lines will be addressed with some preliminary results showcased in an attempt to meeting these challenges, including an extended LOF algorithm for continuous sequence detection and an AFE behavioral modeling platform.

    Center for Functional Nanomaterials Seminar Cu-CHA in Emission Control Dr. Xiaofan Yang BASF Corporation Friday, July 10, 2015 11:00 a.m. Building, 735, Conference Room A Chabazite supported Cu is the most promising catalyst platform for implementing a NH3/urea-based Selective Catalytic Reduction (SCR) system to remove hazardous NOx gases from the lean-burn engine exhaust. Whereas in-depth spectroscopic and other studies have attempted to identify key features of the catalytic cycle previously, a deep understanding of the SCR mechanism amenable for a systematic improvement of the catalyst performance continues to be elusive. To establish a more rational approach to catalyst optimization and identify chemically sound design principles based on the thermodynamics and kinetics of the key steps of the underlying NOx-transformations we developed a quantum chemical model and benchmarked it to match vibrational data from Diffuse Reflectance Infrared Fourier Transform spectroscopy resulting in plausible assignments of each observable intermediate to specific oxidation states of Cu and NO-binding properties. This approach allows for making a much more precise assignment of the experimental vibrational data to key intermediates potentially involved in the catalytic cycle of the SCR reaction and provides a high-resolution model that can be examined to develop a micromechanistic proposal for the catalytic reaction cycle that is chemically meaningful and is logically consistent. In addition, the presentation also covers industrial application utilizing Cu-CHA in emission control. Host: Qin Wu

    Friday, July 10, 2015, 11:00 am

    "Longitudinal space charge (LSC) effects are generally considered as detrimental in free-electron lasers as they can seed unwanted energy modulations and emittance growth. There has however been an increasing interest in devising accelerator beam lines capable of sustaining this LSC instability as a mechanism to operate as a coherent light source. In such a cascaded longitudinal space charge amplifier (LSCA), initial noise present in the beam density is amplified via the interplay of longitudinal space charge forces and properly located dispersive sections. To date most of these studies have been carried out with a one-dimensional impedance model for the LSC. We use an available grid-less three-dimensional N-body ``Barnes-Hut'' algorithm to simulate the 3D space charge force in the beam combined with ELEGANT and explore the limitations of the 1D model often used. We investigate, via numerical simulations, the performances of a cascaded LSCA beam line at the Fermilab's Advanced Superconducting Test Accelerator (ASTA)."

    Hosted by: Laurence Littenberg

    Why are we made of matter, not antimatter? Where such asymmetry comes from remains one of the biggest mysteries in physics. In this talk, the speaker will take you through the process how physicists design a scientific experiment aiming to address this important question. We will examine the thinking behind, review the current progress, and discuss the challenges in the future.

    Joint Nuclear Physics and Particle Physics Seminar

    "Understanding the nature of neutrinos via neutrinoless double-beta decay"

    Presented by Wenqin Xu, Los Alamos National Laboratory

    11 am, Small Seminar Room, Bldg. 510

    Tuesday, September 8, 2015, 11:00 am

    Hosted by: Jin Huang

    Neutrinos provide a critical portal to physics beyond the Standard Model, yet the nature of neutrinos is largely unknown, including the neutrino mass hierarcy and if neutrinos are Majorana particles. Majorana particles are fermions that are their own antiparticles. Neutrinos being Majorana particles would explicitly violate lepton number conservation, and would pave the way to understand the matter-antimatter asymmetry in the universe. Neutrinoless double-beta (0 ) decay is a hypothesized process where two neutrons decay into two protons and two electrons simultaneously without emitting neutrinos. It is possible only if neutrinos are Majorana particles, and it is the only feasible way to experimentally establish the Majorana or Dirac nature of neutrinos. The observation of 0 decay would also provide complementary information related to neutrino masses. After decades of experimental e orts, the next generation 0 decay experiments will have a signi cant discovery potential to observe 0 decay, if neutrinos are indeed Majorana particles. In this talk, we will discuss the physics of neutrinoless double beta decay and review the experiments searching for it. We will focus on the Majorana Demonstrator, a 40-kg modular Germanium detector array, which searches for 0 decay in 76Ge and aims at demonstrating a path forward to next generation 0 decay experiments.

    The talk will discuss recent measurements in the top quark sector, the heaviest known elementary particle known so far, performed at the Fermilab Tevatron Collider and at the LHC. I will highlight Tevatron results that are competitive to those at the LHC, especially regarding the top quark mass and production asymmetry. The talk will also present CMS results on the top quark mass and Yukawa coupling. I will discuss the implications for the standard model electroweak sector regarding the vacuum stability. I will conclude with an outlook towards the high luminosity phase of the LHC and the CMS silicon detector upgrades required for the high luminosity phase.
