<br>
Holly has the new gas filters ordered for BB and we can hook them up to the gas lines in BB GEMs today evening after the techs are done with the work in the Hall. <br>
<br>
Yesterday, in the RC meeting, Kondo wanted to check with Nilanga again whether we really want to do it right now with just one week of running remaining as things have been quite stable with the GEMs for the last few weeks.<br>
Could you please advise us on what your preference would be to put these new gas filters on BB GEMs in terms of timeline?<br>
<br>
Best,<br>
