Have measurements been done to indicate that the spike thermocouples are
closer to the in-tube thermocouples than they appeared to be when Jim McVittie
measured them last night?

We certainly have to have some hardware problem to result in uniformity as bad
as we have seen for the last couple of days but, if I interpret your comments
correctly, nothing has been found to be out of order.  Am I correct in
interpeting this as we still don't know what is wrong?



> This morning we did the following: 
> · checked the packing-it looked tight but we pushed it in farther. 
> · Measured the quartz position on three tubes and set the position of # 4 equal to #2 
> · Checked all TC positions- all looked fine 
> · Closed the damper to the position it was for the pre-tube clean 
> Additional info: 
> · The torch was replaced during the tube pull for possible contamination issues.  It was pulled this morning and
> inspected no visual defects
