We set up an ISP250 to pump on the dewar jacket for CP6 (Mid-X). The pump was turned on at 1:23 PM. The pump was placed on two pieces of foam, see attached picture.
Will add a comment to this report when the pump is turned off today.
We haven't turned this pump off in the end at MX. Instead, we've let it run until 5/31 (Wednesday) morning at CP6, and transposed it to CP5. Currently, it is still pumping.
