Control of the emittance in the booster will become crucial to ensure the nominal performance of the storage ring injection. The SOLEIL I booster is already equipped with a Visible Synchrotron Radiation Monitor (MRSV). This equipment, made of an extraction mirror and a simple optical system, was originally planned to be used only for beam presence verification but has not been used routinely for operation since the commissioning in 2005. The control and acquisition systems had to be refreshed to be usable again and allow the beam size measurement along the booster energy ramp. The extraction mirror was replaced due to unexpected degradation leading to a second spot appearing on the camera. This paper traces back the MRSV upgrades from understanding the cause of mirror degradation until mirror replacement and the first proper beam visualisation, achieved at the beginning of 2023.
