Abstract: The quasi-isentropic compressibility of a helium plasma has been measured using a spherical experimental chamber, as well as an X-ray diffraction complex consisting of three betatrons and a multichannel optoelectronic system for the detection of X-ray images. The density of the compressed helium plasma of about $8$ g/cm$^3$ has been obtained in the experiment at a pressure of $5000$ GPa. Analysis of the data indicates that helium at the measured parameters is in a single ionized state.
