<p style="margin-top: 0px; margin-bottom: 0px;"><br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;">The Hall C magnet will remain cold at 4K and be powered throughout the SAD.</p>
<p style="margin-top: 0px; margin-bottom: 0px;">Power supply tuning and maintenance will require that the magnets be operated to full currents. No dates have been set for when Danfysik will be on site for this.</p>
<p style="margin-top: 0px; margin-bottom: 0px;"><br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;">Dump resistor testing will be done after the new resistors arrive. No date for this as the PO is tied up with legal about contract language.</p>
<p style="margin-top: 0px; margin-bottom: 0px;"><br>
</p>
<p style="margin-top: 0px; margin-bottom: 0px;">Training of the HB magnet to higher currents may be carried out if time and resources are available.</p>
