The Environment Corps program at the University of Connecticut approaches community engagement by combining teaching, service learning, and extension work. This model of engagement harnesses the power of trained undergraduates in conducting meaningful and actionable projects for communities, building on the topical knowledge, outreach experience, and community contacts of seasoned extension professionals, and in turn expanding the reach of their programs. Over 175 projects have been completed in partnership with 96 municipalities, nonprofits, or other entities. The program has documented benefits to both students and partner communities. The program team is interested in assisting others to adapt the model. 

We present numerical simulations used to interpret laser-driven plasma experiments at the GSI Helmholtz Centre for Heavy Ion Research. The mechanisms by which non-thermal particles are accelerated in astrophysical environments, e.g., the solar wind, supernova remnants, and gamma ray bursts, is a topic of intense study. When shocks are present, the primary acceleration mechanism is believed to be first-order Fermi, which accelerates particles as they cross a shock. Second-order Fermi acceleration can also contribute, utilizing magnetic mirrors for particle energization. Despite this mechanism being less efficient, the ubiquity of magnetized turbulence in the universe necessitates its consideration. Another acceleration mechanism is the lower-hybrid drift instability, arising from gradients of both density and magnetic field, which produce lower-hybrid waves with an electric field that energizes particles as they cross these waves. With the combination of high-powered laser systems and particle accelerators, it is possible to study the mechanisms behind cosmic-ray acceleration in the laboratory. In this work, we combine experimental results and high-fidelity three-dimensional simulations to estimate the efficiency of ion acceleration in a weakly magnetized interaction region. We validate the FLASH magneto-hydrodynamic code with experimental results and use OSIRIS particle-in-cell code to verify the initial formation of the interaction region, showing good agreement between codes and experimental results. We find that the plasma conditions in the experiment are conducive to the lower-hybrid drift instability, yielding an increase in energy ΔE of ∼ 264 keV for 242 MeV calcium ions. 

An extensive faculty partnership at the University of Connecticut (UConn) that reaches across college and departmental lines is engaged in a project that seeks to enhance, expand, institutionalize, and study a new model for community engagement. The model, called the Environment Corps (E-Corps), combines the familiar elements of classroom instruction, service-learning, and extension outreach to create a method of engagement that aims to benefit students, faculty, surrounding communities, and the university community itself. This article describes the structure and history of E-Corps; details the institutional setting, faculty partnerships, and pedagogical strategies involved; and discusses early evidence of impacts and future prospects.
