The implementation of the new SNEB configuration has been completed:

• the North cavity has been locked on B7 in air;
• the beam has been almost centered on the camera and the photodiodes moving both the bench and the picomotors;
• the North cavity has been locked on B4;
• the beam has been roughly centered on the quadrant B7_QD2: the beam in not clippend on M3, light is arriving on the sensors, it was difficult to understand the exact meaning of the B7_QD2 signals (to be further checked);
• the beam reflected by M3 has been centered on the new beam dump installed last Monday;
• the beam reflected by the quadrant has been sent on the corresponding beam dump;
• the balancing of the bench has been checked;
• the microtower has been closed and pumped up to a decent level of vacuum (slighlty lower than 1 mbar) -> some more pumping should be done during the next maintenance or whenever is possible;
• the mSAS has been recentered in vacuum;
• angular and position loops have been closed in vacuum;
• the North arm has been re-aligned and re-locked in vacuum wihtout troubles.
