|Figure 1. The HISCALE experiment: complete instrument assembly.||Figure 2. Schematic outline of detector telescope configurations in the two separate mechanical mounts.|
|Figure 3. Instantaneous look direction of the four LEMS/LEFS telescopes on the 4p steradian sphere. One spacecraft rotation (~12 sec) takes each telescope through 360°, and thus the entire sphere is covered each rotation.||Figure 4. Block diagram of electronics system for the HISCALE experiment.|
|Figure 5. Calibration data. Energy-loss matrix for the composition aperture for various incident ions. The solid lines outline the discrete element groups detected (Table 3).||Figure 6. Spectrograms of the ion and electron intensities measured by the HISCALE instrument for days 80-90, 1991. This interval occurred at the end of March 1991 when a large solar particle event swept over Ulysses.|
|Figure 7. Spectrograms as in Fig. 6 for day 82 at the beginning of the solar event. The interplanetary shock at ~1540 can be clearly seen.||Figure 8. Spectrograms as in Fig. 6 for day 84 in the middle of the solar event.|
|Figure 9. Time-intensity counting rate plots of proton and iron group channels from the spectrum analyzer for days 80-90, 1991.||Figure 10. Ion flux composition matrix measured by the CA detector system during day 82, 1991, at the beginning of the solar event.|
|Figure 11. Ion flux composition matrix measured by the CA detector system during day 83, 1991.||Figure 12. Ion flux composition matrix measured by the CA detector system during day 84, 1991.|
