No parts are removed.</div><div><br></div><div>- Check for possible activation of beam line components by D3 </div><div><br></div><div>- Cosmics run without field ~1 month, until end of January</div><div><br></div><div>- Remove upstream lead wall ~2d, early Feb.</div><div><br></div><div>- <span style="font-family: Symbol; "><span><span style="font: normal normal normal 7pt/normal 'Times New Roman'; "> </span></span></span>Complete optical survey<span> </span>(target chamber, 12 deg lumi, Moller, wire chambers </div><div> and coils as much as possible) ~ 1 week, Feb.</div><div><br></div><div>- Remove concrete ceiling 1 d</div><div><br></div><div>- Remove sub-detector frames 1 - 2 d</div><div><br></div><div>- Optical survey of 12 deg lumi and WC wrt sub-detector frames</div><div><br></div><div>- Field measurements </div><div> </div><div>Start disassembly of detector March </div><div><br></div><div><br></div><div>Some questions and comments:</div><div><br></div><div>Should the WC and 12 deg lumi cables be cut or removed carefully?</div><div><div>It might be better to cut the cables a few meters from the detector in order</div><div>not to change the weight and possibly the position wrt the sub-detector</div><div>frame before the internal survey.</div></div><div><br></div><div>What field measurements do we need? The complete WC chamber/ 12 deg lumi</div><div>region or some limited number of points?</div><div>It would be quite difficult to get the field measuring device we used during the setup</div><div>of the detector. Using a simpler and smaller device is preferred by Yorck. </div><div>We will discuss the options with Yorck on Friday. </div><p class="MsoNormal" style="margin-left: 36pt; "><o:p></o:p></p><div>I discussed the disassembly with the head of MEA some time ago. Since they will </div><div>be quite busy, he prefers to not to fix the dates for the crane work, but rather do</div><div>this when they have some spare time. </div><div>I think this is fine, since we are not under time pressure. The only time constraint I </div><div>know so far is that the target/vacuum system should be sent to MIT during the summer. </div><div>This shouldn't be a problem. Do you have other constraints?</div><div><br></div><div>The component coordinators/group leader should let me know whether you will ship </div><div>our parts (detectors, electronics, cables, ....) back. </div><div><br></div><div>Please let me know if you have comments. As Douglas mentioned yesterday, we</div><div>will have a first discussion in the weekly meeting next Monday. </div><div><br></div><div>Best regards,</div><div>Uwe</div></div><div><br></div><div><br></div><br><div>
