<div class="">The picture of the beryllium window indicates that the beam spot was elongated, not round, were there changes to the upstream quad(s) after the spot was centered and checked on the screen? </div>

David and I just complete the inspection of the crucble following the 5kW irradiation. The maximum whole-body dose rates were 25-30 mR/hr and the maximum on-contact dose rates were 250-650 mR/hr; therefore, we were able to also obtain picture of the beryllium
window. I have added a folder in the Isotope Production site with photos: <a href="https://jeffersonlab.sharepoint.com/:f:/r/sites/IsotopeProductionDocuments/Shared%20Documents/Photos/5kW_InspectionPhotos?csf=1&web=1&e=nmFM91" id="OLK_Beautified_OWA7550f15a-e40f-cd9e-8822-e89a77787e8f" class="OWAAutoLink _3iLgzr8un7L5GebClucrpV _1qJHlPfY83WgqLBJTIZPj" data-ogsc="" contenteditable="false" style="pointer-events: auto; padding: 0px 1px; border-top-left-radius: 2px; border-top-right-radius: 2px; border-bottom-right-radius: 2px; border-bottom-left-radius: 2px; background-color: rgb(243, 242, 241);"><img alt="" role="presentation" src="https://outlook-2.cdn.office.net/assets/mail/file-icon/png/folder_16x16.png" style="width: 16px; height: 16px; vertical-align: middle; padding: 1px 2px 2px 0px;" class="">5kW_InspectionPhotos</a><span class="Apple-converted-space"> </span>,
