Vertical test stands
Cluster G
Cluster D
The vertical cryostats zone , called Cluster G of about 400 m2 is under upgrade with an extra space called Cluster
D of 150 m2 to accommodate the test of larger diameter magnets @ higher operating current for HL LHC.

Horizontal test benches on going upgrades
Cluster A
The horizontal test zone Cluster A to F excluding D is composed by 10 benches equipped with 5 independent
electrical circuits allowing to test magnets up to 15 kA @ 1.9 K. Two clusters are planned to be upgraded to 20 kA
capacity.
