  • Analysis and Instrumentation for a Xenon-Doped Liquid Argon System
    Analysis and instrumentation for a xenon-doped liquid argon system Ryan Gibbons Work completed under the advisement of Professor Michael Gold Department of Physics and Astronomy The University of New Mexico May 27, 2020 1 Abstract Liquid argon is a scintillator frequently used in neutrino and dark matter exper- iments. In particular, is the upcoming LEGEND experiment, a neutrinoless double beta decay search, which will utilize liquid argon as an active veto system. Neutri- noless double beta decay is a theorized lepton number violating process that is only possible if neutrinos are Majorana in nature. To achieve the LEGEND background goal, the liquid argon veto must be more efficient. Past studies have shown the ad- dition of xenon in quantities of parts-per-million in liquid argon improves the light yield, and therefore efficiency, of such a system. Further work, however, is needed to fully understand the effects of this xenon doping. I present a physical model for the light intensity of xenon-doped liquid argon. This model is fitted to data from various xenon concentrations from BACoN, a liquid argon test stand. Additionally, I present preliminary work on the instrumentation of silicon photomultipliers for BACoN. 2 Contents 1 Introduction 4 1.1 Neutrinos and double beta decay . 4 1.2 LEGEND and BACoN . 5 1.3 Liquid argon . 6 2 Physical modeling of xenon-doped liquid argon 8 2.1 Model . 8 2.2 Fits to BACoN Data . 9 2.3 Analysis of Rate Constant . 12 3 Instrumentation of SiPMs 12 4 Conclusions and Future Work 13 3 1 Introduction 1.1 Neutrinos and double beta decay Neutrinos are neutral leptons that come in three flavors: electron, muon, and tao.

More than just a name. Physicist. Genius. Science pop star. Philosopher and humanist. Thinker and guru. On a par with Copernicus, Galileo or Newton. And: Albert Einstein – from Ulm! The most famous scientist of our time was actually born on 14th March 1879 at Bahnhofstraße 20 in Ulm. Albert Einstein only lived in the city on the Danube for 15 months. His extended family – 18 of Einstein’s cousins lived in Ulm at one time or another – were a respected and deep-rooted part of the city’s society, however. This may explain Einstein’s enduring connection to the city of his birth, which he described as follows in a letter to the Ulmer Abend- post on 18th March 1929, shortly after his 50th birthday: “The birthplace is as much a unique part of your life as the ancestry of your biological mother. We owe part of our very being to our city of birth. So I look on Ulm with gratitude, as it combines noble artistic tradition with simple and healthy character.” 8 9 The “miracle year” 1905 – Einstein becomes the founder of the modern scientific world view Was Einstein a “physicist of the century”? There‘s no doubt of that. In his “miracle year” (annus mirabilis) of 1905 he pub- lished 4 groundbreaking works along- side his dissertation. Each of these was worthy of a Nobel Prize and turned him into a physicist of international standing: the theory of special relativity, the light quanta hypothesis (“photoelectric effect”), Thus, Albert Einstein became the found- for which he received the Nobel Prize in er of the modern scientific world view.

Key Decisions The ExCom voted to move $100k of operating funds to an endowment for a new award. The ExCom voted that a new name (not Otto Laporte) should be chosen for this award. In the coming year, the Award committee (currently the Fluid Dynamics Prize committee) should establish the award criteria, making sure to distinguish the criteria from those associated with the Batchelor prize. The committee should suggest appropriate wording for the award application and make a recommendation on the naming of the award. The ExCom voted to move Newsletter publication to the first weeks of June and December each year. The ExCom voted to continue the Ad Hoc Committee on Media and Public Relations for two more years (through 2010). The ExCom voted that $15,000 per year in 2009 and 2010 be allocated for Media and Public Relations activities.

  • Advisor Input Part 2
    Paul O’Connor Dear Ian and Marcel, Here is the input you requested on the Instrumentation Task Force topics. I have confined my comments to the instrumentation needs of High Energy Physics, although at a multipurpose lab like BNL we see quite significant overlap with other disciplines, particularly photon science and medical imaging. 1. National Instrumentation Board It's unclear what authority this body could have. Perhaps a better model would be an advisory panel to the DOE and NSF or a sub-panel of HEPAP. Coordination with NP and BES programs may be more effective. 2. Targeted Resources at National Labs I support the idea of dedicating a fraction of each labs' LDRD funding to leading-edge instrumentation development. In addition, Increased support for dedicated detector instrumentation groups at the labs is also needed. The more common model, engineering support organizations whose funding comes from charge-back to programs, makes it difficult to develop and sustain the talent and equipment resources needed to respond to next-generation instrumentation needs. 3. National Instrumentation fellowships Few university physics departments promote talented students to follow instrumentation-related courses of study. There are some instances in which a MS in Instrumentation is offered to grad students who fail Ph.D. qualifying exams. The sense that instrumentation is a path for less-qualified students certainly does not promote the development of the next generation of talented instrumentalists. A suitably prestigious fellowship program could help reverse this trend, in conjunction with the Instrumentation schools. 4. Instrumentation schools Of the topics listed for the task force this is one that I most strongly support.
