Houghton University Digital Archives

The Houghton University Archives serves the students, faculty, staff, administration and alumni of Houghton University by collecting and maintaining a historical record of the University story. The Archives collects, organizes, preserves, and makes accessible materials critical to understanding the historic, present, and future mission of Houghton University and to nurturing identity, purpose, and unity in the University community. This DSpace site provides access to some of the Houghton University's digital collections.

    DESIGN AND CONSTRUCTION OF A SCANNING TUNNELING MICROSCOPE FOR THE STUDY OF THIN METAL FILMS
    (Houghton University, 2026-05-06) Tyler, Nathan
    Houghton University is building a Scanning Tunneling Microscope (STM) to analyze the surface of thin metal films in air at an atomic resolution. A dual-stage vibration isolation system is used to reduce noise. Stepper motors move the scanning head toward the sample surface, after which a piezo buzzer scans a tip across the surface while adjusting the height to maintain a constant current. The position of the tip is therefore an image of the surface. All the electronics are controlled by a Teensy 4.1 microcontroller. The hardware, electronics, and software have been successfully tested independently of one another, but not yet as a complete system.

    A NEW EVAPORATOR FOR THE LITHIUM DEPOSITION CHAMBER AT HOUGHTON UNIVERSITY
    (Houghton University, 2026-05-06) Knight, Asher
    Light ion nuclear reaction experiments using ultra-fast high-power lasers performed at the Lab for Laser Energetics (LLE) use thin lithium films to measure nuclear cross sections using Inertial Confinement Fusion (ICF) or Target Normal Sheath Acceleration (TNSA). To make these films, a new lithium evaporator system has been developed at Houghton University. The new evaporator is easier to install, separates the two evaporator boats in order to evaporate one material at time for multilayer targets, uses a linear feedthrough to position the substrates, and incorporates a deposition rate monitor to control the layer thickness. Because lithium reacts with air, the new design allows the creation of a protective layer to coat the lithium film, and the deposition chamber is inside of an argon glove box.

    DEUTERON AND TRITON INDUCED LIGHT ION REACTIONS PRODUCED VIA HIGH-POWER SHORT-PULSE LASERS
    (Houghton University, 2026-05-06) Bo, Andrew O.
    Light ion and neutron nuclear reactions can be induced via Inertial Confinement Fusion (ICF) and Target Normal Sheath Acceleration (TNSA) using high-power, short-pulse lasers like the OMEGA-60 and OMEGA-EP lasers at the Laboratory for Laser Energetics. In order to measure these reactions, the Short-Lived Isotope Counting System (SLICS) was developed. SLICS can be inserted into the OMEGA-60 and OMEGA-EP target chambers using a Ten Inch Manipulator (TIM). As an initial test of the SLICS detector, TNSA deuterons struck a natural lithium target to induce 7Li(d,p)8Li reactions. SLICS then counted the beta decays from the 8Li product nuclei to calculate the 8Li yield, to which predicted yields, calculated using previously measured 7Li(d,p)8Li cross-sections, were compared. The TIM based SLICS is now a standard diagnostic for experiments on OMEGA-60 and OMEGA-EP.
