News question: Know your neutrons?

Quiz time: Show that you know about neutrons!

Join Fermilab News at Work in congratulating Lynn Johnson for winning last week’s quiz. Cable coils of niobium-tin wires are heat-treated at 1,200 degrees Fahrenheit for approximately 2 weeks to convert them into superconductors at operation temperatures. 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. 19.

This week’s question is: How far from an antineutrino interaction can neutrons travel before detection? (Hint: See “Finding the missing pieces in the puzzle of an antineutrino’s energy.”)

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.
