A 40 MV/m accelerating gradient has been obtained in a niobium cavity after a chemical etching by using a three acids mixture. This technique is also called BCP as Buffer Chemical Polishing. This result, the third in the world, allows to hope for findings to improve systematically the thermal breakdown (quench) on BCP treated cavities. The heat treatment at higher temperature after chemistry could be an interesting way, because this means influences the quench position. |
