At LHC Point 4, a refrigerator that cools helium from room temperature to 4.5 K (-268.65 °C) has undergone major improvements in preparation for the HL-LHC
The cold diodes of the new triplet circuits will be installed in a dedicated cryostat in the LHC tunnel downstream of the triplet magnets and close to the LHC beam pipe.
Nearly one year after the start of the assembly activities the first 3-module-device Target Dump Injection Segmented (TDIS) unit is ready to be installed.
