Low-Background Muon and Neutron Benchmarking for Applications in Ultra-Rare Event Searches John Greavu‚ Mentor: Professor Priscilla Cushman Purpose The primary purpose of this study is to measure‚ to a high precision‚ the muon and neutron backgrounds experienced at the Low Background Counting Facility (Fig. 1) in the Soudan Underground Laboratory. An active muon veto shield lining most of the interior‚ in addition to a neutron detector—the Neutron Multiplicity Meter—in the facility‚ allow for benchmark

conventional x-ray machine. When a charged particle accelerates it radiates photons or x-rays. For example‚ in a conventional x-ray tube the electron beam accelerates from a fila ment to an anode‚ where it decelerates rapidly at the anode and emits x-rays (shown schematically in Fig. 2). A different approach is to accelerate (or decelerate) the particle by passing it through a magnetic field. This is what really happens in an accelerator. When the particles curve in the magnetic field‚ x-rays are emitted

The Higgs boson or Higgs particle is a proposed elementary particle in the Standard Model of particle physics. The Higgs boson’s existence would have profound importance in particle physics because it would prove the existence of the hypothetical Higgs field—the simplest[4] of several proposed explanations for the origin of the symmetry-breaking mechanism by which elementary particles acquire mass.[Note 2] The leading explanation is that a field exists that has non-zero strength everywhere—even in

Particle interactions are the cause of everything we know to exist‚ such as the bright lights that illuminate the room you are in or the heat you feel when you stay in the sun for too long. To understand how these particle interactions occur we need to be able to

The actual definition is the emission of high energy particles or waves. This can mean many things‚ but the two most common are electromagnetic waves (photons)‚ or high energy particles released from decaying atoms. The one that I will be talking about is radioactive atoms (the green things that glow in the dark). This kind of radiation is called nuclear

What is the particle theory? The particle theory says that that matter consists of many small particles with spaces in between. The particles are constantly moving‚ the higher it’s temperature‚ the faster they move. All the particles are attracted to each other. The particles move faster and move further apart when heated‚ and the reverse when cooled. Each substance has unique particles that are different from the particles of other substances. Particle theory helps to explain the behaviour of
