Abstract

The Affordable Multiple Aperture Spectroscopy Explorer (AMASE) is a planned high-resolution spatially-resolved spectroscopy survey of the interstellar medium in the Milky Way and nearby galaxies. The prototype telescope and instrument system, AMASE-P, is under development. We provide an update on the instrument design and report the status of this project. A major design change from the previous report is the use of fused silica etched grating in place of VPH grating. The new gratings would provide a significant improvement in the high-efficiency bandwidth of the spectrograph. For fiber positioning on the pseudo-slit, we adopted a new design for the fiber slit blocks to reduce the risk of damaging the fibers during the fiber insertion process and to strengthen the mechanical property of the blocks. We have also chosen octagonal fibers for more uniform near-field and far-field light outputs to yield more stable line spread function. We report the progress of the project and challenges we encountered.
