Analysis of Fault Events in MVDC Architecture
(IEEE, 2009-04)Effective interruption of load currents under both normal and fault conditions presents major challenges in medium-voltage DC distribution systems. In a highly-integrated DC power system, the preponderance of power converters ... -
Current status of the Hobby-Eberly Telescope wide field upgrade
(2012-07)The Hobby-Eberly Telescope (HET) is an innovative large telescope of 9.2 meter aperture, located in West Texas at the McDonald Observatory (MDO). The HET operates with a fixed segmented prima1y and has a tracker which moves ... -
Design and development of a high precision, high payload telescope dual drive system
(2010-07)A high precision, dual drive system has been designed and developed for the Wide Field Upgrade to the Hobby-Eberly Telescope* at McDonald Observatory in support of the Hobby-Eberly Telescope Dark Energy Experiment‡. ... -
Design and development of a long-travel positioning actuator and tandem constant force actuator safety system for the Hobby Eberly Telescope Wide Field Upgrade
(2010-07)The Wide Field Upgrade presents a five-fold increase in mass for the Hobby-Eberly Telescope's* tracker system. The design of the Hobby-Eberly Telescope places the Prime Focus Instrument Package (PFIP) at a thirty-five ... -
Design of the fiber optic support system and fiber bundle accelerated life test for VIRUS
(2010-07)The quantity and length of optical fibers required for the Hobby-Eberly Telescope* Dark Energy eXperiment (HETDEX) create unique fiber handling challenges. For HETDEX‡, at least 33,600 fibers will transmit light from the ... -
