LCLS-II-HE verification cryomodule high gradient performance and quench behavior

S. Posen, A. Cravatta, M. Checchin +43

An 8-cavity, 1.3 GHz, LCLS-II-HE cryomodule was assembled and tested at Fermilab to verify performance before the start of production. Its cavities were processed with a novel nitr…

Development of a cryocooler conduction-cooled 650 MHz SRF cavity operating at ~10 MV/m cw accelerating gradient

R. C. Dhuley, S. Posen, M. I. Geelhoed +1

SRF cavities for particle acceleration are conventionally operated immersed in a bath of liquid helium at 4.2 K and below. Although this cooling configuration is practically and ec…

Simulations of $N b_{3} S n$ Layer RF Field Limits Due to Thermal Impedance

Paulina Kulyavtsev, Grigory Eremeev, Sam Posen

$N b_{3} S n$ performance in RF fields is limited to fields far below its superheating critical field. Poor thermal conductivity of $N b_{3} S n$ has been speculated to be the reason beh…
