Review Of Solid Polarized Targets, Leiqaa Kurbany May 2018

Review Of Solid Polarized Targets, Leiqaa Kurbany

Student Research Projects

In the following pages I review polarized solid-state target briefly. What I discovered through my reading and writing about this technology, that is amazing tool to study the nucleon structure. I started with what is polarized solid-state target, went through Dynamic Nuclear Polarization (DNP) to understanding how it works, then its setup, in what experiments they used polarized solid-state target and some results of these experiments and finally I wrote a brief definition to many of terms, they are important to know to understand what is polarized solid state target.


Exclusive Production Of Phi Vector Meson During Hera-Ii, Brent Lawson Jan 2018

Exclusive Production Of Phi Vector Meson During Hera-Ii, Brent Lawson

Honors Theses and Capstones

The Hadron Electron Ring Accelerator (HERA) in Germany, which ran from 1992 to 2007, is to date the only high energy electron and proton collider. The ZEUS detector at HERA measured the collisions of 27.5 GeV electrons with 920 GeV protons. Elastic vector meson production was measured during the first phase of HERA (HERA-I) from 1992 to 2000 before HERA was upgraded in 2003 (HERA-II) with increased luminosity. The goal of this project was to analyze data collected during the HERA-II run to identify and quantify the exclusive production of the  vector meson. Runs from the ZEUS experiment were …


Sensitivity Of Black Phosphorus To O2 And Atmosphere Measured By Macroscopic Four-Point Probe, Cameron Flynn Jan 2018

Sensitivity Of Black Phosphorus To O2 And Atmosphere Measured By Macroscopic Four-Point Probe, Cameron Flynn

Honors Theses and Capstones

Scientific interest in black phosphorus, a two-dimensional semiconducting allotrope of phosphorus, has increased in the last few years, since it was shown in 2014 to have very good properties for fieldeffect transistors. Unfortunately, practical use of the material is delayed because of its tendency to degrade into a phosphoric oxide when left in air. In this thesis I present the effects of atmospheric air and pure oxygen on the transport properties of bulk black phosphorus with and without light exposure. For continuous measurements carried out by millimeter-scale four-point probe, we see no change in the resistance of bulk samples exposed …
