Exactly right, we actually have similar decisions for HE-CAV0040 and HE-CAV0128 by the Cavity Technical Board. Any of these cavities are still SLAC property and will be stored at Blue Crab until further notice.</p>
<p class="x_x_MsoNormal" style="margin-top: 0px; margin-bottom: 0px;margin:0in 0in 0.0001pt; font-size:11pt; font-family:Calibri,sans-serif">
Currently, we are using some of these rejected cavities for different purposes like the mockup setup of the purge system. Furthermore, we have salvaged – as instructed by SLAC – other rejected cavities at BC for spare parts. So, despite being marked as “rejected”
for string assembly, these cavities are still being used within the framework of HE.</p>

<span style="color:#1F497D">In summary, as we were looking into cavities for the L2 remediation project, we did not catch that the CAVSNs listed in the currently open L2PRD NCR list below had damaged bellows from the L2PRD string assembly. The NCR was written
on the string assembly traveler and tagged against the string SN; however, since the cavity was damaged and removed from the string, we needed an NCR to flag the cavity itself. We decided to write NCRs against the cavities and reference the original NCR #
(see the description). These NCRs can be closed by copying the resolution from the original (referenced) NCR. No action is required for these cavities at this time. </span></p>

Open NCRs were discussed in today’s Quality Board Meeting and I recalled you and I talked about the 3 open ones you used for early cavity work, see below. Can you remind me what needs to happen to close these? I CCed Megan because I though there might be a
request to move the data to LCLS-HE. Teams call me if it’s easier to explain without writing a short novel.
