Abstract: The Cosmic Ray Energetics And Mass for the International Space Station (ISS-CREAM) payload was developed to measure the elemental spectra for a charge range of Z = 1 to 26, with an energy range from ∼10^12 to ∼10^15eV. Launched in August 2017, the ISS-CREAM payload successfully collected data for 539 days until February 2019. The ISS-CREAM instrument consists of several particle detectors: a Silicon Charge Detector (SCD) for charge measurements and a calorimeter (CAL) with carbon targets for energy measurements. It also includes a top counting detector (TCD), a bottom counting detector (BCD), and a boronated scintillator detector (BSD) to help separate electrons from protons. For this analysis, SCD and CAL were used for the charge and energy measurement, respectively, while TCD/BCD and CAL were used for the trigger. The ISS-CREAM proton spectrum has been reported in the energy range of 1.6 − 655 TeV. This proton spectrum deviates from a single power-law, softening at ∼ 9 TeV. This study presents the preliminary helium spectrum from the ISS-CREAM experiment in the energy range of 6 TeV to ∼ 1.1 PeV.
