Hi Brian,<br class="">
<br class="">
Yes - please move both 9068 units to the cabinet in the hall - let me know when this has been done.<br class="">
<br class="">
Yes - let us continue to monitor the 9035 performance on the solenoid.<br class="">
<br class="">
I would rather we left the Torus FastDAQ as is for the Spring run and swap it out with a 9045 after April. I guess we will have to purchase a 9045? Do you have a cost for this?<br class="">
<br class="">
Yes - please move the cryocon and chassis down when you are ready to do so - let me know when this has been done.<br class="">
<br class="">
Cheers<br class="">

One of the 9068s is in the cabinet in the Hall B CH, the other is still on my desk running. Since I don't think I'll learn anything new with it running I can move it down to the cabinet if you'd like.<br class="">
<br class="">
As for replacements, so far we haven't had any issues with the solenoid FastDAQ since replacing it with the 9035. However, it really hasn't been running long enough to say for certain that will resolve all the issues (although it is definitely trending that direction).
I think if we can get through the spring run too that will be enough evidence that the issue was specific to the 906x series.<br class="">
<br class="">
If replacement is something that is seriously being considered I'd suggest swapping the torus FastDAQ with a 9045 for the spring run since that is the current model cRIO and the upgrade to the 9035s we had been using on all the systems DSG implemented.<br class="">
<br class="">
I also have a spare Cryo-Con I can take down to the cabinet.<br class="">
<br class="">
As for the LV chassis I have a spare and one of the prototypes/first articles (basically used for parts). I was still messing with it on and off so I'm not quite ready to put it in the cabinet, but I will do so when I'm done. For now just note they're in EEL/231?<br class="">
