News question: Know your accelerator magnets?

Quiz time: Show that you know about accelerator magnets!

Join Fermilab News at Work in congratulating Kathryn Duerr for winning last week’s quiz. The Cherenkov Telescope Array is observing the galactic halo to understand how gamma rays might be formed from dark matter particles bumping into one another and self-annihilating. Thank you to everyone who participated!

Now, show off your knowledge of the news coming out of Fermilab in this week’s quiz! A winner will be randomly selected from all lab employees and users who submit the correct answer to today’s question by noon CT today, Sept. 12.

This week’s question is: At (a) what temperature and for (b) how long did the team heat-treat cable coils of niobium-tin wires to convert them into superconductor at operation temperatures? (Hint: See “Fermilab achieves world-record field strength for accelerator magnet.”)

Good luck! We will announce the winner and answer next week.

Past winners are welcome to participate in the quiz each week. However, only one win per person will be recognized in any 30-day period. The winner is recognized in the following week’s quiz and rewarded with a small token.
