Yesterday and Today

Pump would not start.

Called in electrician -- found a breaker flipped and flipped it back.  

Removed questionable gate valve to make system more vacuum tight.  

Went to turn on pump.  It sparked and smoked.  

It didn't start.  

Found I had pinched and grounded a wire. I hung my head in shame.  

Called back in electricians -- fixed the wire and found a broken fuse.  Replace broken fuse.  

Started pump.  

All systems go.  

Turned on liquid nitrogen.  

I left the room.

I came back and the pumps were off.

"There was a pop! and a flash of light!"  

Pumps would not start.  

I checked fuse box -- found broken fuse and replaced it.  

Started pump.  

All systems go.

Pressures started rising.  

Turned off pumps.  

Did a leak check -- found two large leaks that have been there since I first started in the lab.  

Fixed the leaks.  

Started pump.

All systems go.  

Glorious, oh, glorious success.  

Running low on oil.  

Turned off pumps.  

Started pump.

All systems go.

Turned on liquid nitrogen.  

Did not leave the room. 

Heard a pop and a large spark fly across the room.

Turned off the pumps.

Went to turn on pump.

It didn't start.

I checked the fuse box -- found a broken fuse and replaced it.  

On our last fuse.  

Do we try again?
