Brian,

Please do not forget that at some point HPS SVT will come to the clean room for repairs. Most likely it will be end of June or beginning of July (depends on travel restrictions at SLAC).

Thanks, Stepan

We are trying to work it out. Valery said the will start RICH work no sooner than end of May and will occupy first the small space. I am also considering EEL125 for CVT commissioning which doesn't require the clean room. What we need now is the patch panel and cables properly labeled, HW interlock software tested with ambient sensors so that when we mount the SVT on the cart and connect the SVT cooling and purging, we can use it. I can have SVT warm for days but not weeks, the safety interlocks should be operational and not affect the commissioning schedule. I do not want a temporary solution like cRIO, all interlock software and hardware should be the same which will be used in the hall.

Has it been worked out where the CVT is going to be located? It wasn't clear to me if there was still issues with GEM moving out or not.

I'm not going to be able to move racks/crates myself, but smaller/lighter things like patch panels I can.

The cRIO has been tested and if things are in their place I can connect it tomorrow night. Or I could just move the patch panel to the cRIO and connect it there?
