	The unique feature of the VEPP-4M electron-positron collider is wide energy range (1 - 4.75 GeV) available for experiments in high-energy physics. Energy spread value of the beam is an important parameter in a choice of energy step during measurement of e⁺e⁻ -> hadrons cross sections as well as it has a strong influence on the statistic collection time required for the scanning of narrow resonances like planned for the nearest future scan of Upsilon(2s) meson. Thus, it is important to control energy spread of the beam and measure it operatively and reliably. The paper presents measurements of the beam energy spread at the VEPP-4M electron-positron collider in its complete energy range. Energy spread was calculated from bunch length measured by "PS-1/S1" streak camera with picosecond temporal resolution. In order to exclude the influence of collective effects on bunch length, we measured length of low-intensity bunch. Values of energy spread calculated from bunch length were checked by the measurements of energy spread based on registration of beam decoherence. The impact of the Touschek effect in the beam energy spread at low energy range (1.0 - 1.5 GeV) is discussed.

The unique feature of the VEPP-4M electron-positron collider is wide energy range (1 - 4.75 GeV) available for experiments in high-energy physics. Energy spread value of the beam is an important parameter in a choice of energy step during measurement of e⁺e⁻ -> hadrons cross sections as well as it has a strong influence on the statistic collection time required for the scanning of narrow resonances like planned for the nearest future scan of Upsilon(2s) meson. Thus, it is important to control energy spread of the beam and measure it operatively and reliably. The paper presents measurements of the beam energy spread at the VEPP-4M electron-positron collider in its complete energy range. Energy spread was calculated from bunch length measured by "PS-1/S1" streak camera with picosecond temporal resolution. In order to exclude the influence of collective effects on bunch length, we measured length of low-intensity bunch. Values of energy spread calculated from bunch length were checked by the measurements of energy spread based on registration of beam decoherence. The impact of the Touschek effect in the beam energy spread at low energy range (1.0 - 1.5 GeV) is discussed.
