Quiz time: This week we’re spotlighting news about the MAGIS-100 interferometer.
But first, join Fermilab News at Work in congratulating Pierrick Hanlet for winning last week’s quiz. The accelerating gradient achieved in the cryocooler-cooled accelerator cavity is 6.6 million volts per meter. 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, Oct. 3.
This week’s question: Why is strontium a better atomic clock than rubidium for measuring the time it takes laser light to repeatedly travel along a vacuum tube? (Hint: See “MAGIS-100: Atoms in free fall to probe dark matter, gravity and quantum science.”)
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.
