Hello- The stacking rate has been ~1mA/hr since stacking started at 21:00 yesterday. However, the vacuum in the A60 sector (down stream of the detector) is poor and is essentially equivalent to a gas jet; the beam lifetime is ~40hrs without the E835 jet on (normally it is >150hr). This problem limits the amount of beam that can be stacked. There is a plan to look into this problem at the end of this store. After a meeting that included S. Pordes, S. Werkema, and D. McGinnis, it was decided to stack until midnight tonight and start a 7 point psi' scan. The goal is to be finished the scan between Thursday 0800-1200. There will be a E835 meeting this afternoon; Stephen will arrange a time (the default is 5pm penthouse). Keith
