How much was the Tevatron worth? That is, what value did society obtain from the 28 years of operating this particle accelerator?
Professor John Womersley, a
UK big-science official, recently (and perhaps rashly) attempted to provide a back-of-the-envelope answer.
The
Symmetry Breaking blog summarizes his talk-- which I attended-- and gives a link to a video of it.The Tevatron was completed in March 1983 and ran until September 2011. Womersley considered the cost of constructing and operating the accelerator and its experiments - about $4 billion in today’s currency - and found that, over its lifetime, the Tevatron had returned its investment roughly tenfold. [...]
According to the balance sheet at the end of Womersley’s exercise, $4 billion went into the Tevatron and roughly $50 billion came out.
The calculation is imprecise, but, Womersley said, “it confirms at least my gut feeling that there is a plausible case that it has been a very, very important economic driver over the last few decades.
“And it would be interesting if somebody could pay somebody to do this properly, as I make no claim that I’ve done this properly.”
