ED - Kuzin, Maxim TI - Tests of the Gun Prototype for the Electron Cooling System of the NICA Collider J2 - Proc. of COOL2021, Novosibirsk, Russia, 01-05 November 2021 CY - Novosibirsk, Russia T2 - Workshop on Beam Cooling and Related Topics T3 - 13 LA - english AB - The efficiency of the electron cooling depends on the electron beam quality produced be the electron gun. The characteristics of the electron gun were tested on the test bench with the linear transport channel. For the beam diagnostics, we used beam position monitors alongside with the W-Re wire sensor for 1-D quantitative profile measurements. We also used a high-definition CCD camera with high sensitivity for qualitative 2-D measurements of the electron density distribution via the wire thermal radiation.
