Late entry.

Last Tuesday 3 ion pumps were incorporated to the filter cavity tube.  The ion pumps were installed some time ago, and they remained valved out until last Tuesday.
The ion pumps are located on the filter cavity tube crosses B4, B5 (installed here) and C1 (installed here).
New MEDM screens were created for the signal for each pump (see first attachment), each respective signal is obtained from each of the ion pump controllers, for these ion pump we are using the LPC GAMMA type controllers.  For the pressure effect see second attachment.

To incorporate the ion pumps, FC-B-4 and FC-B-5 to the rest of the filter cavity 3 valves were closed, FCV-3, FCV-4 and FCV-5.  Then to incorporate ion pump FC-C-1, valve FCV-6 was closed.  After the performance of the ion pumps was confirmed all the gate valves were opened.
