REhnu dish-based CPV: Module performance and planned 100 kW plant

Autor: Stalcup, Thomas, Angel, Roger, Strittmatter, Peter, Whiteside, Andy, Geary, Andrew, Sodari, Frank, Rademacher, Matt, Didato, Nick, Ayala, Silvana

A REhnu CPV module uses a 2.6 m(2), back-silvered glass reflector to focus sunlight into a 150 mm diameter receiver housing 36 multijunction cells. Current modules use commercially available 8.8 mm cells operated at 950x concentration with a cell eff

On-grid performance of REhnu's 8-mirror CPV-T tracker

Autor: Stalcup, Thomas, Angel, Roger, Geary, Andrew, Sodari, Frank, Rademacher, Matt, Whiteside, Andy, Will, John, Didato, Nick, Strittmatter, Peter

REhnu has built and tested two 6 kW CPV-T trackers using dish-receiver architecture. In these trackers, only the light collection elements are large, namely mirrors on dual axis trackers. The inherently small parts, the multijunction cells, are packa

Dissertation/ Thesis

Design and Construction of a Multiple Beam Laser Projector and Dynamically Refocused Wavefront Sensor

Autor: Stalcup, Thomas Eugene

Adaptive optics using natural guide stars can produce images of amazing quality, but is limited to a small fraction of the sky due to the need for a relatively bright guidestar. Adaptive optics systems using a laser generated artifical reference can

On-sky wide field adaptive optics correction using multiple laser guide stars at the MMT

Autor: Baranec, Christoph, Hart, Michael, Milton, N. Mark, Stalcup, Thomas, Powell, Keith, Snyder, Miguel, Vaitheeswaran, Vidhya, McCarthy, Don, Kulesa, Craig

Publikováno v: Astrophys.J.693:1814-1820,2009

We describe results from the first astronomical adaptive optics system to use multiple laser guide stars, located at the 6.5-m MMT telescope in Arizona. Its initial operational mode, ground-layer adaptive optics (GLAO), provides uniform stellar wavef

Report

A Reflective Gaussian Coronagraph for ExAO: Laboratory Performance

Autor: Park, Ryeojin, Close, Laird M., Siegler, Nick, Nielsen, Eric L., Stalcup, Thomas

We report laboratory results of a coronagraphic test bench to assess the intensity reduction differences between a "Gaussian" tapered focal plane coronagraphic mask and a classical hard-edged "Top Hat" function mask at Extreme Adaptive Optics (ExAO)
