Description
The ILC (The International Linear Collider) project has not yet started, however basic technology development must continue.
ITN (ILC Technology Network) is an international framework for carrying out technology development.
ITN is a project that started in FY2023 and will continue for five years.
Several technical issues have been proposed as development items at ITN, and each item will be developed through international cooperation.
One of the technology development items includes manufacturing, cooling, and RF testing the cryomodule.
The cryogenic group will need to install new equipment to cool the cryomodules.
The refrigerator (Linde LR280) currently operating at KEK will be dedicated to ITN.
Since the cryomodule test stand and the helium refrigerator are approximately 100 meters apart, installing a transfer line to transfer the liquid helium is necessary.
Additionally, the installation of 2K refrigerators, vacuum pumps, in-line purifiers, etc. is also considered.
