RESUMO
The GOLDHELOX Project is a student run project to construct a robotic solar telescope that will be used to take images of the sun in the soft X-ray region (171181Å) of the spectrum. The optical system uses a microchannel plate (MCP) detector. We tested the MCP to familiarize ourselves with and verify that MCP's can be used to image soft X-rays. Soft X-rays were created by a Manson source attached to a proportional counter to determine the amount of emitted X-rays detected by the MCP. The voltages on the MCP were varied to observe responses of varying voltage differences. Most of the observations were visible observations along with images made by a 35 mm camera with a telephoto lens. We found the 1000 V difference to produce the strongest and clearest images.
RESUMO
NASA G-133, also known as the "GoldHelox Project", is a fully autonomous, soft X-ray, solar telescope designed for use on board the space shuttle. Conceived, designed and built by students at Brigham Young University, it will image the sun with a spatial resolution of 2.5 arc-seconds with a temporal resolution of one second. The instrument will image X-rays with wavelengths between 171Å and 181Å coming from highly ionized Fe lines in the sun's corona. Data will consist of several hundred high resolution photographs that will help in understanding the initial phases of solar flares, and the relationship between solar flares and the physics of the coronal-chromospheric transition region. This paper briefly outlines the project's goals, gives a brief overview of the construction and operation of the instrument and addresses the unique aspects of running a predominantly undergraduate research project. It summarizes the lessons learned to date, and the current project status.
