<p>Dear Annalisa,</p>
<p>Is this related to the email from Volker last week, we didn't
hear from you on that email of request from RGK? Did you make
request of RGK on our behalf and how many weeks did you request?
where does one week come from?<br>
</p>
<p>Could you please give us more information on the running
conditions beam energies?</p>
<p>Best regards,</p>

<pre>Dear Annalisa,
on Friday we had a CCC meeting to discuss the change in the accelerator schedule for 2018 and 2019.
The discussion was specifically focussed on the 4 week extension that are being considered for the Spring 2019.
The rational we have been following is to use this additional time to compensate for the losses that
the different Run Groups will have for the delayed start of the machine after the summer shutdown
and the other changes that are being done to the schedule. Among these, the extension of the 10.6 GeV
running to after Thanksgiving and the consequent shortening of the low energy running at the end of
this year are directly affecting Run Group. In this regard, what is being considered is to assign to
Run Group K a week in the Spring 2019 after RG-B. To take a sound decision on this,
we would like to have your feedback on the possibility for RG-K to have a publication from the 2018 run
with the reduced time and on what would be the gain if another week of beam would be allocated in the Spring.
Best regards,
Raffaella
