We ran the LQ1 up to 2500 amps and checked for over heating of the SCRs. They are running hot, but will probably survive. 3.5 GeV is a little above that, the SCRs may be able to make it. I would say, try 3.5Gev. If the supply trips off, let it cool, bring it back up 200 amps lower in current, and that will be the best we can do until people are around during the week and maybe we can come up with some ideas.
