I have had several responses to the CEBAF/Cryo email about the
schedule for transitioning to 6GeV. First, this decision has not
been made yet. My query was to make sure this is a viable
alternative in case we have to go that route. In the e-mail,
there is the following statement:<br>
<blockquote> The SCN must be warmed up and decontaminated in order
to support <b>any</b> 2K operation. (emphasis added)<br>
</blockquote>
This means it will be days before CEBAF would be at 2K, if not a
week (my estimate, not Cryo's). Not only is there the warm up and
cool down of SCN there are U-tube operations and other heavy lifting
by Cryo. So we have time (about a week) to plan for this, if it is
the path taken. <br>
<br>
I hope to have a path forward by the Wednesday 1:30 scheduling
meeting. <br>
<br>
Presently the machine is in the restricted access state and the
control room is not staffed. Contact the crew chief on-call for
any MCC related business. <br>
<br>
I appreciate the quick response to the 6GeV configuration question,
this is useful information going forward. So far I have not heard
of any show stoppers. <br>
<br>
Peace and heres to better days ahead!<br>
