    keyword=EPR measurement

    We performed an EPR AFP this morning just before the controlled access. The screen shots are attached. The resonance is at 15.65 MHz. The AFP measurement shows 38.7 % . But looking at the lock in channels , its clearly seen that the AFP is not locked. Yi made a correction after looking into it and the polarization turned out to be 45%. We will do another AFP when we come back after the controlled access and turn on the laser again
