<p class="xmsonormal">At this stage, the Conceptual Design Report (CDR) should be used as the baseline for the EIC technical design in all aspects. As the project evolves, major technical improvements/changes, after a designated procedure, shall re-establish

<p class="xmsonormal"> <o:p></o:p></p>
<p class="xmsonormal">After formal reviews and collection of comments from the Technical Change Control Board, I have approved the following change to be implemented into the EIC technical design baseline:<o:p></o:p></p>
<p class="xmsonormal"> <o:p></o:p></p>
<p class="xmsonormal">Adoption of actively-cooled screen as baseline for the RHIC superconducting magnets used in the HSR and inclusion of RF finger bellows in the plan.
