The Cryogenics Group made great progress in getting to this point but uncovered excessive heat loads in the NL. They need to bring equipment into the tunnel and will start on Monday morning. First opportunity for operations beyond 500 keV is targeted for Tuesday swing shift. I am cancelling all beam operations until day shift Tuesday. The plan for Tuesday will be Injector recovery to 500 keV in anticipation of starting operations beyond that point on swing shift.<br><br>Rest up and enjoy the weekend. See you Monday.<br><br>Mike<br></div></body></html>
