The CERN experiment NA48 studies the matter-antimatter
imbalance by measuring the decay of particles called neutral kaons
and antikaons, their antimatter counterparts. These particles
decay in several ways, and careful study gives an accurate handle
on nature's apparent preference for matter over antimatter.
A key component of the NA48 detector is a very low temperature
cooling vessel, or cryostat, built under an ISTC programme. The
cryostat was manufactured by Moscow-based company Krunichev Enterprises,
better known for the "Proton" space rocket and the "Mir" space
station, in collaboration with ENTEK, a large institute of the
Russian Federation's Atomic Energy Ministry.
