<div class=""><u class=""><b class="">1.</b> New weekly <b class=""><i class="">beam-delivery-updates</i>
</b>mailing list</u></div>
<div class=""><br class="">
</div>
<div class=""><span style="font-size: 14px;" class="">This mailing list is open to all users interested in keep up to date with ongoing operations and developments in the beam delivery systems at TRIUMF. It covers all experimental program beams at the lab,
from proton beams in the meson hall, electron beams with the e-linac, and both stable and radioactive isotope beams at ISAC and ARIEL. It also will include beam schedule updates. The content derives from the weekly report from TRIUMF beam delivery operations
to senior management. </span></div>
<div class=""><span style="font-size: 14px;" class=""><br class="">
