<p class="x_xmsonormal"><span style="color:black">I am wondering if your BOE for the EIN and the LEC include some cost associated to the 200 MHz SPS cavities we recently received from CERN. I believe a few will be used for the LEC and 1 or 2 for the EIN. </span></p>

<p class="x_xmsonormal"><span style="color:black">The cost to bring them into BNL was paid under NCRF WBS (not a lot of money, just transport plus tariffs) but should be transferred to the appropriate WBS. You should also take credit for the cost savings associated
to this operation. I estimated that the whole lot was worthy about 20 M$. </span></p>
