Abstract. Variations of parameters of twice-ionized helium ions – He++ ions or α-particles – in the solar wind plasma during the interplanetary shock front passage are investigated. We used the data measured by the BMSW (Bright Monitor of Solar Wind) instrument installed on the SPEKTR-R satellite, which operated since August 2011 to 2019 and registered 57 interplanetary shocks. According to received data, the parameters of He++ ions were calculated: velocity Vα, temperature Tα, absolute density Nα and relative density (helium abundance) Nα/Np. The correlation of changes in helium abundance Nα/Np with the parameters βi, θBn and MMS were investigated.

Short summary
The collisionless shocks are very complicated and important field of nowadays researches. We used the data measured by the plasma spectrometer BMSW (Bright Monitor of Solar Wind) to investigate variations of parameters of twice-ionized helium ions He++ in the solar wind during the interplanetary shock passage. It was shown that the changes of He++ abundance are depended of interplanetary shock parameters.
