<p>Draft:</p>
<ul>
<li>Previous magnet meeting decision was to go for triplet magnet</li>
<li>Dominique gave a presentation</li>
<li>Gilles de Godec brainstorm EPC power converter point view for the magnet needs and different option</li>
<li>The magnet 355 A for operation at 0.6 T, so a 2P type Polarus power converters of 500 A (360 V) can be used</li>
<li>Suggested cable cross section would be 240 mm^2 (but leave this for EN-EL to decide), for outer insulation they can take 1kV. Cable resistivity </li>
<li>Interlock between power converters should be such that if one of the converters (main or trim) goes busted, the other should trip as well to avoid beam deflection. </li>
<li>Three options:</li>
</ul>
<p>(1) 2 Power converters for one complete triplet magnet (1 for main and 1 for two trims) - 8 power converters (safest option)</p>
<p>(2) 2 Power converters for two instruments, 1 for two mains and 1 for 4 trims. - 4 power converters, must have all the system magnetically identical which unfortunately not guaranteed as the one H and one V instrument on one beam influence differently on the other beam.</p>
<p>(3) 1 power converter for one twiplet - 4 power converters, less power converters but no knobs to tune !</p>
<ul>
<li>Cooling water needed for the power converters in the service tunnel, aproximately 100 kW, new request for EN-CV</li>
<li>The physical envelope of the PC rack will be provided by Gilles with possible location in the tunnel (or Miguel helps identify one for integration)</li>
<li>Needs ethernet connection for each EPC PC rack</li>
<li>Gunn will send plan ID to Gilles</li>
<li>AC power request needs to be added in the PLAN for each PC (400 V/200 A, 3Phase), socket type will be provided by Gilles</li>
</ul>
