HiRES - A high-resolution stigmatic extreme ultraviolet spectroheliometer for studies of the fine-scale structure of the solar chromosphere, transition region, and corona

Timothy, J. G; Berger, T. E; Morgan, J. S; Walker, A. B. C; Jain, S. K; Saxena, A. K; Bhattacharyya, J. C; Huber, M. C. E; Tondello, G; Naletto, G (SPIE, 1991-08)

HiRES is a high-resolution stigmatic EUV spectroheliometer whose 45-cm Gregory telescope is coupled to a spectrometer employing a single toroidal diffraction grating and an imaging pulse-counting multianode microchannel ...
HiRES: High-resolution extreme-ultraviolet spectroheliometer toroidal diffraction grating performance evaluation

Berger, T. E; Bergamini, P; Walker II, A. B. C; Jain, S. K; Saxena, A. K; Bhattacharyya, J. C; Huber, M. H; Tondello, G; Naletto, G; Baker, P. C (SPIE-The International Society for Optical Engineering, 1993)

The HiRES sounding rocket payload has been described in detail in previous SPIE Proceedings. Here, optical design of the toroidal grating spectrograph is presented and discussed. Ray tracing results are presented which ...
