The gun HVPS current limit is set to 0.2 mA. If you draw more current the HVPS will trip off. Please don't trip off the gun. The gun can provide more current than this, the EPICS limit can be increased. Do you expect needing more beam current than 200
uA?</div>

<div dir="auto">An idea related to high current run this weekend:</div>
<div dir="auto">First what is the highest current Hall C dump can take at 5th pass?</div>
<div dir="auto">If the answer is more than 74uA, then why not direct all current to Hall C @5th pass?</div>
<div dir="auto">Doing this will eliminate (1) extraction at 3rd pass, (2) beam line to Hall A, and (3) all RF separators (less chances for failure).</div>
<div dir="auto"><br>
</div>
<div dir="auto">In any case, we should add B beam to the mix of A and C beams even if we don't adopt my suggestion above. That would make the high current beam test easier to perform.</div>
<div dir="auto"><br>
