Hi all,
Great help & many thanks!
Here's an update and summary from Richard:
We have fixed the leak from our Oxford AS500 magnet. Thanks to everyone who
replied to the post and made helpful suggestions. Great to have such a
community to help each other out.
The leak location is indicated by the yellow dots and was detected using a
leak detector. Removing revealed a broken O-ring which we replaced with the
one from the charging stick (until we can source one of the correct size).
Not difficult to replace, just took the courage to try something new! There
are no leaks now, and fortunately not from any other parts of the magnet
either. The flow meter into the helium recovery system is showing a steady
reading as compared to zero before. Hopefully our recovery rates will show
a healthy increase. No icing was observed despite the big leak.
Best wishes
Richard Lewis
