Bell jar problem

[Pengyu Fan]

Hi all,

The bell jar problem is back again, and it could be lifted but can't be lowered. I saw Jim K. also ran into the same problem this morning, but somehow fixed it later.

Liz and I tried, but failed to figure out what Jim H. meant by the sticky switch in the maintenance logbook.

It feels terrible to leave the bell jar just open in the air, but there is really nothing we could do to fix the problem.

Cheers,
Pengyu
