Organizing PDFs

I'm trying out Zotero as a tool for organizing pdfs of journal articles. My journal articles are always hidden away in multiple folders on my computer and it's hard to find them when I need them. Zotero lets me access them from a central location, and I can tag and search them. If you are viewing certain websites, like Socrates or Physical Review, Zotero will import title/author information for you. It will also export Bibtex.

If you are using a Mac (I don't think any of us are), Papers is the new, awesome scientific paper organizer for Macs. I was searching for a PC version, and that's how I came across Zotero.

PPMS cryopump regeneration

We have been having a lot of trouble with the PPMS cryopump. The manual claims we should only need to regenerate the pump once every 500 uses, but we are needing to regenerate every ~30 uses. Ernest at QD says that, every time we regenerate in dewar, we should run the regeneration command 5 or 6 times, and every time we regenerate out of dewar, we should run it 4 times, then do an in dewar regneration after finishing the out of dewar regeneration. I've modified the regeneration sequences accordingly, and we should all remember to do an in dewar regeneration after finishing an out of dewar regeneration.

Digitizer

This is something I learned from Suchitra: You can use a digitizer such as Engauge Digitizer to read data points off of published graphs.
