<b>Subject:</b> [EXTERNAL] FTBF scheduling update</span></p>

<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">Hello all,</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">Thank you all for submitting requests for the upcoming FTBF run. I’m writing to provide an update on the scheduling process. The accelerator complex is facing two technical challenges that will affect the upcoming beam year. At this
time we expect beam startup to be delayed from November and the run to be shortened but do not know how much. We have not started building a schedule until more information is clear.</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">In early August there was a fire at the Kautz Road substation, badly damaging one of the 4 transformers that are used to power the Main Injector. Since that time, the Infrastructure Services (ISD) and Accelerator (AD) divisions have been
hard at work to understand the condition of the lab’s remaining transformers and what the impact would be on the accelerator complex. The latest news is that ISD believes that 4 transforms can be used (2 at the Master substation and 2 at the Kautz Rd substation),
and calculations suggest that with those 4 transformers they can power the whole accelerator complex, including the Main Injector and Switchyard. There is additional work to put the complex in this configuration and the current projection is to start running
beam in the Booster in early November with MI and Switchyard to follow at an unknown scale. It is likely to take longer to commission the beam lines in this configuration and tune up to deliver stable, quality beam. The complex has not run in this configuration
before and in dealing with this issue some summer shutdown work was deferred until next year, increasing the possibility of failures. If the complex can run in this configuration, it will be possible to receive the standard switchyard slow spill. </p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">The second issues is that the set of MI heat exchangers that supply cooling to the LCW systems are now severely corroded. They are inspected and cleaned every other year but not measured for the thickness of the walls. The heat exchangers
are pressure vessels, and the wall thickness just recently were found to be less than what is required for the rated pressure. The heat exchangers cannot operate without repair/replacement or change in the process/documentation and the pressure rating of
the exchangers. A vendor will be investigating next week to determine what path forward is possible and the timescale.</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">I will continue to provide updates as we know more about the situations. I am happy to discuss further with anyone who has questions. I’ve sent this out to the emails associated with schedule requests, please distribute among your teams.
At this time we do recommend exploring beam time at other locations as the beam time at FTBF will be reduced. When we know more about the length of the run we will work with everyone on optimizing and prioritizing the available beam time.</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">Thanks,</p>
