<p class="xmsonormal"><span style="font-family:"Arial",sans-serif">I agree that at least the power leads and probably the water hoses will have to be removed. The 2F03 corrector will also have to be removed to get at the flange upstream of the magnet. So
this will have to be coordinated with DC Power, S&A, and the vacuum and rigging folks. We do have very good measurements of the current position of the magnet from S&A and Joe has measured the current cartridge offsets. We would want to move the holes more
than 27 mm to reduce the cartridge offsets to close to zero. After that the magnet would have to be realigned by S&A and then the vacuum chamber would get made up. I was unable to see any vacuum chamber interferences that would prevent it from moving upstream
in the magnet. It looks like it moves away from interferences.</span><o:p></o:p></p>

<p class="xmsonormal">Hi All,<o:p></o:p></p>
</div>

<p class="xmsonormal">Here are a few shots of the dipole in question and the vacuum window. The dipole support plate looks as if the is sufficient space to cut new holes for the alignment cartridges. Neil will comment on rigging the magnet.<o:p></o:p></p>
</div>
<div>
<p class="xmsonormal">The window change is tight quarters but there is 6” - 8” behind the flange bolts to the back of the shield wall - tight but doable. No space fro clean hood though...<o:p></o:p></p>
