keyword=SMS: Significant Reduction in LHe Flow to Hall CSince we began pumping on the perimeter transfer line the flow of LHe to the flow has dropped dramatically (see Figure 1). The pump was turned on at about 10:05; prior to that point the flow was averaging around 8.5 to 9 g/s. After the pumps were turned on the flow has dropped to around 7 g/s which seems to be roughly where the SMS wants to sit. The average setting of the supply valve (JT4) has changed from around 43% to 33%. The level seems more stable over the short period of time I have been monitoring it.
