<p><span style="font-size:10.0pt; font-family:"Arial",sans-serif; color:black">Activity: The ASD Power Supply Group with assistance from the AES/MOM Group have been actively diagnosing the source of the problem. As of this morning, additional diagnostic tests
have resulted in the decision to replace the injection septum magnet assembly. A spare septum magnet assembly had already been located, electrically tested and confirmed as leak tight and is in the process of confirmatory testing. Work planning and control
efforts are progressing in coordination with HP, Rigging & Lifting, WSH and a host of AES support groups. The removal/installation time as well as bake-out and demobilization, followed by SR conditioning and start-up, has a low probability, of infringing
on the start of user operations on October 1<sup>st</sup>.</span></p>
