Brian and I were debugging the solenoid fastDaq cRIO. We re-deployed the labview program with the FPGA filter version. We are monitoring temperatures in the coils (~5 K), Cooldown has been recovered, but we are still waiting to get low temperatures in te vcl, they are about 12K. It has been planed to start power up the solenoid in a few minutes.( about15:30) Regards, Pablo <br>_______________________________________________<br>Dsg-internal mailing list<br>Dsg-internal@jlab.org<br>https://mailman.jlab.org/mailman/listinfo/dsg-internal<br></div></div><br>_______________________________________________<br>Dsg-hallb_magnets mailing list<br>Dsg-hallb_magnets@jlab.org<br>https://mailman.jlab.org/mailman/listinfo/dsg-hallb_magnets<br></div></div></body></html>
