ºÚÁÏרÇø

The fourth and last Conceptual Design Review (CDR) for the ºÚÁÏרÇø cryogenic system was held this week. The CDR for cryodistribution was conducted during 20-21 July, successfully meeting all requirements.
 
The main function of the ºÚÁÏרÇø is to cool down and maintain the required cryogenic operating conditions of the ºÚÁÏרÇø cold components such as the magnets, the cryopumps and the in-tokamak thermal shields. The cryoplant on the ºÚÁÏרÇø platform will produce the required cooling power at the three required operating temperature levels, namely at 4 K, 50 K, and 80 K.
 
The distribution of cooling power will be accomplished through a set of cryodistribution cold boxes, which control the cooling power into the ºÚÁÏרÇø cold components by forced flow.
 
A unique feature of ºÚÁÏרÇø cryodistribution is the mass flow rate of the cold rotating machines: the machines will have a mass flow rate that ranges up to 3 kg/s whereas existing limits are around 1 kg/sec. Such high flow rates are necessary to satisfy the cooling requirements of the ºÚÁÏרÇø superconducting magnet system ... another unique system in many ways.
 
With the successful conclusion of the cryodistribution CDR, the conceptual design of ºÚÁÏרÇø's cryogenic system is now completed and the way paved for the construction of the world's second largest cryogenic facility (following CERN).
