WorksheetsCERN Large Hadron Collider
Total questions: 25
Worksheet time: 13mins
What is the circumference of the LHC?
57.9 metres
12.9 km
27 km
Why did they make the LHC so large?
Nobody knew how big to make it, so they just guessed
The tunnel was left over from an old particle accelerator.
The circumference in km is a lucky number in Switzerland where it was built.
What does CERN stand for?
the Center for Energy, Radiation and Nuclear Study
the European Organization for Nuclear Research
the Center for European Research and Negotiations
Where does the LHC get all the protons that go zipping around?
from Oxygen
from Hydrogen
from Helium
What does NOT happen to particles before they go into the LHC?
The electrons are stripped.
The protons are fed into preliminary accelerators.
The particles are cleaned and rinsed.
What happens when the protons smash together?
It happens so rarely, we don't really know.
Makes a black hole.
Makes a mini Big Bang.
Huge magnets inside the LHC help steer the protons beam. Are the magnets hot or cold?
They get really hot.
They are really cold.
What were scientists NOT looking for in the LHC?
superpartners
black holes
Higgs Boson
What CANNOT be discovered at the LHC?
string theory
supersymmetry
how particles gain mass
How many proton collisions occur each second in the LHC when it is running?
There are only a couple every few months!
450
600 million
What does the Proton Synchrotron do?
lines up the protons
washes the protons
speeds up the protons
What is the Higgs boson named after?
the Higgs field
the physicist who theorized its existence
the brother of the physicist who theorized its existence
What scientific theory did the Higgs "complete"?
Physics
supersymmetry
the Standard Model
What are hadrons?
a nickname that theoretical physicists give experimental physicists.
particles composed of quarks.
elementary particles.
How certain were scientists that they found the Higgs in 2012?
There was a 1 in 3.5 million chance the data was wrong.
There was a 1 in 3.5 million chance they were observing incorrectly.
There was a 1 in 3.5 million chance they would see what they saw but it wasn't the Higgs.
How much did the LHC cost?
$6 billion
$3 billion
$985 million
How do physicists see proton collisions?
a big magnifying glass.
a special super-slow-motion camera.
with lots of detectors and lots of data
Why does LHC need the "large" adjective?
The larger the accelerator, the more protons it can hold.
It needs a long straight line before it turns.
Nice, long, gentle curves accommodate more acceleration.
Besides proton collisions, what other work is done in the LHC?
alchemy
heavy lead ion collisions
astrological calendars
The LHC was shut down for 28 months in December 2012 because of
a strike by French power workers.
the need for refurbishment before going to higher engines
black holes
skiing
An LHC power failure in 2009 was caused by the circuit having
some rain on
a gluon
a baguette on
a pion
If you had a ZZZ event, you would have
a nightshift in the ATLAS control room.
a very rare type of proton proton collision
a very boring type of proton proton collision
a www upgrade
A fermion is:
A badly-spelled hadron.
A French farmer who owns fields inside the LHC ring.
A particle with half-integer spin.
Someone who works at Fermilab.
The Standard Model is
a small white CERN van.
Kate Moss
The current best theory of particle physics
The theory of everything.
What is this a picture of
The BICEP2 telescope for detecting gravitational waves.
The Chooz neutrino detector
A cold minion with chickenpox
The vanguard of our Dalek overloards
