  • 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 
    Berger, T; Bergamini, P; Kirby, H; Timothy, J. G; Walker, A. B. C; Bhattacharyya, J. C; Jain, S. K; Saxena, A. K; Huber, M. C. E; Naletto, G; Tondello, G (Cambridge University Press, 1993)
    The HiRES sounding rocket payload is designed to obtain very high spatial, spectral, and temporal resolution images of the solar chromospheric and coronal plasmas in the extreme ultraviolet (EUV) wavelength range from 500 ...
  • 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 ...
  • A Single-Cell Photopolarimeter 
    Jain, S. K; Bhattacharyya, J. C (Indian Institute of Astrophysics, Bangalore, 1987-02)
    A simple, single-cell photopolarimeter has been developed for use at the cassegrain focus of the 102 cm Ritchey-Chretien reflector at Kavalur. The design and performance of the instrument are discussed
  • A Single-Channel Polarimeter 
    Jain, S. K; Bhattacharyya, J. C (International Astronomical Union, 1986)
    The authors have developed a single-channel photopolarimeter to measure polarization to ≡1%, with an accuracy of 0.1%. Laboratory tests show that the performance of the instrument matches the requirements.
