NRA award the heliospheric instrument for spectra and composition at low energies (hiscale) on the ulysses spacecraft and the electron proton alpha monitor (epam) on the advanced composition explorer (ACE) are nearly identical instruments as epam was the flight spare for hiscale. This allows similar tools to be developed for the two instruments to generate nearly identical data products. Over the past year, we have constructed a method for extracting daily and hourly-averaged, high-resolution energy spectra for various z>1 ions using the pulse height analyzer (PHA) system. We propose to modify this method for use with the hiscale instrument and produce a similar data product.

Over the past year, we have constructed a method for extracting daily and hourly-averaged, high-resolution energy spectra for various ions using the public height analyzer (PHA) system. We propose to modify this method for use with the hiscale instrument and product a similar data product. The ulysses spacecraft explored regions of the heliopolar orbit allowed observations at nearly all latitudes and from radial distances. The addition of these highly resolved spectra for the heavier ions will complement the cosmic RAY data from instruments on ulysses, and will allow direct comparison to in-ecliptic measurements taken by the ACE/epam instrument. By plotting the energy deposited in the c and d detectors of epam s CA-60 telescope, the different ION species will trace unique tracks allowing for positive identification and total energy measurement of the incident ions. The counts are sorted along these various tracks into twelve bins resulting in a very high-resolution energy spectrum over a couple of decades of energy. As one might expect, the flux is low for these heavy ions, but using the two-parameter PHA measurements, the background noise is minimal permitting integration of these counts over long time intervals.
