After this stack there will 4-8 hrs of beam studies (shielding assement to allow more protons on target at larger repetition rate) with reverse protons. The shutdown will occur next week with the last stacking cycle to occur at 06:00 Monday April 24; we hope to be data taking Mon-Wed. It is hoped that stacking can begin again Fri/Sat Apr 28/29. We will have to evaluate the time left after this stack so that most/all of Sunday is for stacking. Currently, there are only two requests for access (Cary and Michelle). If you need to make an access, please send Stephen and myself your request. Keith
