High Speed Imaging and Data Acquisition Systems for Studies of Transient Plasma Dynamics
Abstract
The dynamics of transient plasma phenomena play a critical role in a number of areas of interest to the U.S. Department of Defense (DoD). These phenomena range in scale from breakdown associated with detonator wires to space weather events such as coronal mass ejections (CMEÕs) from the sun. We (Professors Gilmore and Lehr) and our colleagues at the University of New Mexico (UNM) currently have several DoD-funded projects related to laboratory studies of fast transient plasma phenomena, including a DoD HBCU/MI research grant to Prof. Gilmore awarded in August 2015 to study the detailed physics of CMEÕs interacting with the solar wind through scaled laboratory experiments and numerical modeling (ARO award number A16-0057-001). In this proposal, we are seeking funds to purchase high speed imaging (cameras) and data acquisition equipment that will greatly enhance our capabilities to study fast transient phenomena at UNM. Profs. Gilmore and Lehr both have significant prior experience using the proposed equipment on our current projects (where borrowed equipment has been used) and/or on prior projects outside of UNM. This equipment will directly benefit several current DoDsponsored projects of Profs. Gilmore and Lehr, as well as those of colleagues at UNM. Each of these projects has significant student involvement by both graduate and undergraduate students, and this would directly benefit UNM students. Additionally, we plan to utilize the equipment in specific undergraduate ÒLearn One Teach OneÓ learning experience in fast time measurements. Specifically, we propose to buy three high-end cameras that will provide three complementary types of high speed imaging: 1. A multi-frame intensified CCD (ICCD) camera capable of acquiring 12 images in = 5 ns, with = 5 ns between frames (Hadland Ultra 24). 2. A high dynamic range streak camera able to record images over times ranging from 500 ps to 1 ms, with 5 ps resolution (Hammamatsu C-7700 system). 3. A single frame ICCD camera able to capture high resolution single images as fast as 1 ns (Andor iStar 312). Additionally, we propose to purchase 4. A set of low f number (fast) standard lenses of various focal lengths for the two ICCD cameras. 5. A set of deep memory 60 Msample/sec digitizers to acquire data that will complement the visible camera images, such as measurements from magnetic probes (ADLink PXIe-9848).
