Update on the Slit-Jaw Context Imaging System of the Marshall Grazing Incidence X-ray Spectrometer (MaGIXS)
Abstract
The Marshall Grazing Incidence X-ray Spectrometer (MaGIXS) is a sounding rocket payload that will provide unprecedented spatial and spectral resolution data of the sun in extreme UV wavelengths, yielding new data on high frequency coronal heating events and perhaps insights into the coronal heating problem. To fully utilize the capabilities of the spectrometer, the telescope needs to be precisely steered towards regions of interest and the data that is gathered needs to be aligned with existing observations from other instruments; a slit-jaw context imaging system is being developed to image the sun for these purposes. Consisting of a ruggedized camera and lens mounted off the optical axis of the telescope and imaging a lumogen-coated plate at the telescope's focal point, the design of the slit jaw system involves optimizing between several parameters to meet demanding resolution requirements at extremely low light levels. The flight camera, optic, and offset angle have been selected already; using a resolution target and OSD control system to experiment with camera settings, the optimized camera settings (integration time, gamma, gain) for flight have been determined. A dummy dataset with the system imaging a simulated sun will additionally be generated and will be supplied to the team developing the pointing software that steers the telescope based on the images.
