If necessary, before starting this work, we could <br>schedule a meeting with the operators to discuss what we need to do.<br><br>By the end of the next week, we plan to install the electronic panel on <br>the RICH, rotate again down the RICH, remove the stiffening tool, <br>install the exit panel and re-install the stiffening tool.<br><br>Finally, at the beginning of the week of Nov. 20 we will install the <br>frontal panels.<br><br>The activities on the mirrors and on the aerogel will run in parallel <br>during the next two weeks.<br><br>Best regards,<br>Marco<br></div></div></body></html>
