  In the scope of SOLEIL II, the booster must also be up­graded to re­duce from 130 to 5~nm.​rad the emit­tance of the beam de­liv­ered to the ring. 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.
