Hello Everyone,

I would like to follow up on my last post about He leaks on oxford magnet
(500MHz).  Thank you everyone for your thoughtful suggestions and
recommendations. It has been 2 weeks since we repaired the 500MHz magnet. 
David Gardner from SuperCon replaced the top-hat and all the o-rings. 
He did an excellent job.  Many of you probably know him.  The average
He lost over the last 2 weeks is 0.48%, compared to 0.44% historical performance. 
The magnet is 22+ years old.  It should last for the next 10 years :) I learnt
a new skill as well, but I think it's too risky to do it on my own.  I will
put it on the budget plan for NMR maintenance. 

Have a wonderful week.

Best,
Hla Win
