研究了束流辐射在高能e（+）e（-）储存环对撞机（SRC）中的作用。由于单个高能束致辐射光子的发射而导致的粒子损失被证明对SRC亮度施加了基本限制，在能量为2 E（0）<$140 GeV的正面碰撞和2 E（0）<$40 GeV的蟹腰碰撞。考虑到束辐射，我们探讨了2 E（0）=240-500 GeV范围内SRC的可行性，这对Higgs玻色子的精确研究是有意义的。在2 E（0）=240 GeV时，SRC被发现与线性对撞机竞争;然而，在2 E（0）=400-500 GeV时，可达到的SRC亮度将比期望的小15-25倍。
The role of beamstrahlung in high-energy e(+)e(-) storage-ring colliders (SRCs) is examined. Particle loss due to the emission of single energetic beamstrahlung photons is shown to impose a fundamental limit on SRC luminosities at energies 2E(0)≳140 GeV for head-on collisions and 2E(0)≳40 GeV for crab-waist collisions. With beamstrahlung taken into account, we explore the viability of SRCs in the 2E(0)=240-500 GeV range, which is of interest in the precision study of the Higgs boson. At 2E(0)=240 GeV, SRCs are found to be competitive with linear colliders; however, at 2E(0)=400-500 GeV, the attainable SRC luminosity would be a factor 15-25 smaller than desired.
