in the town of lead a retired Gold Mine
houses the Sanford underground research
facility Tom cor God a professor at
University College London is a founding
member of a team of researchers drawn
from universities around the world
that's on the hunt for dark matter to
get down a mile um it takes a better
time this experiment up on the surface
just wouldn't be able to run at all it's
just far too C
sensitive after the 10-minute ride down
it's on to a battery powered locomotive
followed by a brief hike to get to the
cavern that holds the
lab of the Lux Zeppelin or LZ detector
experiment the core of the experiment is
Zenon it's liquid Zenon it's Zenon gas
that's been condensed and we've got to
keep that clean and we've got to keep it
cold and so much of what we'll see
around here is all for that really LZ
isn't the only experiment using cooled
Xenon but it now leads the pack in
sensitivity it's the front runner now
and so we're entering Discovery
territory direct Dark Matter detection
experiments go back to the
1980s Xenon based experiments similar in
design to LZ to the
2000s so far all the experiments
combined have detected
nothing we can see them crushing but the
process constantly Narrows down what
Dark Matter could possibly be when we do
see the S1
