[RASMB] turbo-molecular pumps in Beckman XLA XLI

[Walter Stafford]

First of all. I should say that this was not my idea, although I was the first to implement it. I do not remember who was the first to suggest a turbomolecular pump.

And Beckman had an able hand in this: without Rick Cole's helping hand and access to a machine shop to make the flange adaptor, it probably would not have happened. Oh, and we had some extra cash lying around: that helped a lot.

So, ... credit where credit is due.

We recently had an install of a new XLA and found out that even the XLA's come with turbo pumps standard.  This made me wonder if Beckman ever wrote a thankyou letter to Walter for pioneering this hardware improvement, which thought led me to write a thank you letter to Walter for this and also for all the years managing and contributing to the RASMB list for biophysics scientists.
