P2.00001: Search for Prompt Lepton-Jets with ATLAS Data Sarah Ferguson, Bernhard Meirose, Harisankar Namasivayam, Joseph Izen, Grygorii Sokhrannyi A search is presented for a new, dark sector gauge boson with a mass of about 1 GeV/c$^{2}$ and decaying to jets of collimated electrons and/or muons. The analysis is performed with data collected by the ATLAS detector at the Large Hadron Collider in proton–proton collisions. Results using run 1 data with center-of-mass energy of 8 TeV are presented along with prospects for run 2 data with center-of-mass energy of 13 TeV. [Preview Abstract] |

P2.00002: Design and Fabrication of the protoDUNE Dual Phase LArTPC Animesh Chatterjee The WA105 protoDUNE Dual Phase Liquid-argon Time Projection Chamber (LArTPC) is a large demonstrator based on the GLACIER design, with a 6x6x6 m3 (appr. 300t) active volume. Dual-phase LArTPCs are one of the far detector technology options foreseen for the Deep Underground Neutrino Experiment (DUNE) at Fermilab. Dual Phase (DP) refers to the extraction of ionization electrons at the interface between liquid and gaseous argon and their amplification and collection in the gas phase. ProtoDUNE will be operating at the CERN neutrino platform test beam facility. It not only serves as the engineering prototype of the FD, but will also demonstrate the concept of a very large dual-phase LAr TPC and calibrate it with charged particle test beam. We will briefly discuss the actual dimension of the design, fabrication, testing, installation and commissioning of the detector components at CERN. [Preview Abstract] |

P2.00003: Construction of the Field Cage for the DUNE Prototype Detector Shashank Kumbhare The Deep Underground Neutrino Experiment (DUNE) is an international project at Fermilab for precision neutrino property studies. The 40kt Liquid Argon (LAr) Time Project Chamber (TPC) technology used for the DUNE detector and high intensity proton beams will enable physicists to potentially transform our understanding of neutrinos. The TPC detectors of DUNE use field cage (FC) to generate a strong uniform electric field for the ionization electron drift to the anode. The FC for the protoDUNE detector, a large-scale prototype for DUNE, is a 6m x 6m x 6m active volume cubical structure. The walls of FC consist of extruded aluminum profiles held with fiber reinforced plastic (FRP) I-beams. The FC is divided into 8 modules with 2 modules on each side wall, and each module is further divided into 3 sub-modules making a total of 24 sub-modules. The assembly of a sub-module includes attaching 6-inch I-beams with 3-inch I-beams and mounting the Al-profiles and then connecting different submodules together to make a full sub-module. I will present the quality control procedure, preparation for FRP parts and the assembly procedure for these sub-modules, including some mechanical tests and possible improvements of the structure.

P2.00004: Contributions to the ProtoDUNE Field Cage construction process Daniel Koss In the building of the ProtoDUNE Field Cage, teamwork and ingenuity are required in all facets of the construction process. Everyone must do their best to bring both physical and mental contributions to the project, while operating in an efficient manner in both regards. As a team leader in the preparation and inspection of the Field Cage components, and the coordinator of the shipping of these parts, my job is to keep work flow moving towards a swift but complete goal. The ProtoDUNE Field Cage is a test of time and team management skills that will assist coordination of other projects in the future. [Preview Abstract] |

P2.00005: Quality Control of ProtoDUNE Field Cage Fabrication Bradley Hale The ProtoDUNE project at CERN has a dual-phase detector. Compared to a single-phase detector, the dual-phase is intended to increase the number of signals through a large electron multiplier. The first phase is liquid argon that contains a field cage maintaining an electric field to attract electrons to gaseous argon. The skeleton of the field cage consists of 3'' I-Beams and 3 different submodules that have unique 6'' I-Beams. Each I-Beam needed to pass a visual inspection, and have a tolerance less than or equal to 0.5 mm for each slot placement to be acceptable to use in the assembly of the field cage. Failures can contaminate the liquid argon, lower the effective volume of the field cage, or not be able to be connected to the field cage. This study analyzes the I-Beams and the findings were sent out to be simulated for their severity. [Preview Abstract] |
