	A. Paladino KEK, Tsukuba, Japan
	The SuperKEKB accelerator, the upgrade of the KEKB machine, will operate at an unprecedented instantaneous luminosity of 8x10³⁵/cm²/s¹, providing the Belle II experiment an expected integrated luminosity of about 50 inverse ab in ten years of operation. With the increased luminosity, the beam background is expected to grow significantly with respect to KEKB, leading, among other effects, to possible damage of detector components and suppression of signal events. We present studies done during the Phase 2 operation of SuperKEKB to evaluate the contribution of each background source, such as Touschek effect, beam-gas scattering, synchrotron radiation, and injection background. We also present studies performed on collimators and other solutions adopted to mitigate beam backgrounds in the interaction region.

The SuperKEKB accelerator, the upgrade of the KEKB machine, will operate at an unprecedented instantaneous luminosity of 8x10³⁵/cm²/s¹, providing the Belle II experiment an expected integrated luminosity of about 50 inverse ab in ten years of operation. With the increased luminosity, the beam background is expected to grow significantly with respect to KEKB, leading, among other effects, to possible damage of detector components and suppression of signal events. We present studies done during the Phase 2 operation of SuperKEKB to evaluate the contribution of each background source, such as Touschek effect, beam-gas scattering, synchrotron radiation, and injection background. We also present studies performed on collimators and other solutions adopted to mitigate beam backgrounds in the interaction region.
