Warm Compressor system Overview and status of the PIP-II cryogenic system
A Martinez, J Creus Prats, W Soyars +8
The Proton Improvement Plan-II (PIP-II) is a major upgrade to the Fermilab accelerator complex, featuring a new 800-MeV Superconducting Radio-Frequency (SRF) linear accelerator (Li…
Modeling the cooldown of cryocooler conduction-cooled devices
Ram C. Dhuley
Cryocooler conduction cooled devices can experience significant cooldown time due to lower available cooling capacity compares to convection cooled devices. Therefore, the cooldown…
Experiments On A Conduction Cooled Superconducting Radio Frequency Cavity With Field Emission Cathode
Y. Ji, R. C. Dhuley, C. Edward +5
To achieve Ampere-class electron beam accelerators the pulse delivery rate need to be much higher than the typical photo injector repetition rate of the order of a few kilohertz. W…
