Question
The Advanced Light Source facility at this lab is a major source of soft X-ray research. For 10 points each:
[10h] Name this lab whose Bevatron proton accelerator first observed the antiproton and was used in Luis Alvarez’s bubble chamber. This lab overlooks and is partially named for a University of California campus.
ANSWER: Lawrence Berkeley National Laboratory [or LBNL; accept Berkeley Radiation Lab; prompt on Lawrence Radiation Lab; prompt on University of California, Berkeley; reject “Lawrence Livermore National Laboratory” or “LLNL”]
[10m] Ernest Lawrence, for whom the lab is named, won the 1939 Nobel Prize for developing this device while at Berkeley. Particles in this device have a frequency equal to [read slowly] “q B over 2 pi m.”
ANSWER: cyclotron [prompt on particle accelerators; reject “synchrotron”]
[10e] Lawrence also used the cyclotron to develop the calutron (“CAL-yoo-tron”), which was used to separate this element’s 235 and 238 isotopes during the Manhattan project.
ANSWER: uranium [accept uranium-235 or uranium-238; accept U]
