CCR finished tuning the beam and greater beam lifetimes were observed (~24 minutes and 100mA max current). They adjusted the aligment with the Compton laser, compensated for the realignment at the target, and tuned the quads on the East side of the ring. The purpose of this was to improve the beam polarization.

Tancredi worked in the D-tunnel after this and reduced the coinc window to 80ns (the neutron TDC spectrum was observed to be close to zero outside of this window).

Vitaliy measured low ABS degree of dissociation and polarization. He will send BRP results soon.
