<p class="MsoNormal">Hi Mike,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">All cavities mentioned below are “R&R” cases. There will be an additional 20 brand new cavities from RI later this year and next for L2RB.<o:p></o:p></p>
<p class="MsoNormal">The reason I reached out is exactly about traceability. Feel free to drop the L2RB in your SN in Pansophy, however, you can’t call those cavities 0XXX if they are repurposed L2HE cavities, otherwise you would mix them up with L2 cavities.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Just as a simple example, L2RB-CAVR106 just had its successful VTA test. In the corresponding traveler (and the inspection travelers before) it is listed as “0106”. The L2 project should have had an 0106 before and that one is not this
cavity, but the one <u>R</u>106 of L2HE. Does that make sense?<o:p></o:p></p>

<p class="MsoNormal">Hi Mike,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve caught a slight discrepancy in the SN numbers for the new L2RB cavities in the system. Overall, I suggest replacing the “HE” in “HE-CAVRXXX” with “L2RB”.<br>
However, we need to distinguish between former L2 and L2HE (production) cavities. The way this is done is that the L2 cavities have a leading 0 while the L2HE cavities have an R.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Currently, this mostly affects the two reuse cavities from L2-J11. Those are
<b>L2RB-CAV<u>0</u>167</b> and <b>L2RB-CAV<u>0</u>140</b>. I want to make sure to avoid any confusion with HE cavities CAVR140 and CAVR167.<o:p></o:p></p>

<p class="MsoNormal">As of now, the L2RB traveler SN selection lists those all with a leading 0. We should correct this to avoid confusion with old L2 cavities. Would it be possible for you and the
