Below is the schedule for the upcoming days. Recent changes include
removing Yves from Sunday Swing so he can support Hall-A Moller
work during Sunday mid-Day/early swing (or whenever it happens).<br>
<br>
If we resolve this instability we can "stand down"......but......<br>

<p>A very humbling effort so far. The optics work that started
Thursday evening and converge a bit before mid-night on
Friday looks great. However since about 1am this morning
we've been chasing an energy instability that results in BLM
trips at the high dispersion points (namely 1C12, but
sometimes it is other BLMS speak up).</p>
<p>The Arc2 sync. light monitor clearly shows the energy
instability, but we've yet to identify the source. Several
cavities have been by-passed, all cavities are in the
process of being phased up, hoping that the offender will
stand up, no luck so far. Aperture check looks great through
the A line, but a wobbly beam won't make it through.</p>
<p>the hall is patiently waiting. </p>
<p>If this issue gets resolved, the program is to perform a
BCM calibration up to maximum current the beam can delivered
or has been authorized and then the Hall will perform a
target boiling test. These goals have a drop dead time of
8am tomorrow morning. </p>
<p>CW, a true test of the machine, no place to hide....</p>
