THPB091	Mechanical Design of a High Power Coupler for the PIP-II 325 MHz SSR1 RF Cavity	1354
	O.V. Pronitchev, S. Kazakov Fermilab, Batavia, Illinois, USA
	The Project X Injector Experiment (PXIE) at Fermilab will include one cryomodule with eight 325 MHz single spoke superconductive cavities (SSR1). Each cavity requires approximately 2 kW CW RF power for 1 mA beam current operation. A future upgrade will require up to 8 kW RF power per cavity. Fermilab has designed and procured ten production couplers for the SSR1 type cavities. Status of the 325 MHz main coupler development for PXIE SSR1 cryomodule is reported.

THPB092	Mechanical Design of a High Power Coupler for the PIP-II 162.5 MHz RF Quadrupole	1357
	O.V. Pronitchev, S. Kazakov Fermilab, Batavia, Illinois, USA
	PXIE is a prototype front end system for the proposed PIP-II accelerator upgrade at Fermilab. An integral component of the front end is a 162.5 MHz, normal conducting, continuous wave (CW), radiofrequency quadrupole (RFQ) cavity. Two identical couplers will deliver approximately 100 kW total CW RF power to the RFQ. Fermilab has designed and procured main couplers for the CW RFQ accelerating cavity. The mechanical design of the coupler, along with production status, is presented below.

THPB097	New Possible Configuration of 3.9 GHz Coupler	1373
	S. Kazakov Fermilab, Batavia, Illinois, USA
	The LCLS-II superconducting accelerator supposedly will use 3.9 GHz (3-d harmonic) superconductive cavities. A new possible configuration of 3.9 GHz main coupler is presented in the papar. This configuration contains two coaxial ceramic windows, a cold and a warm one. Inner conductors of windows are connected through the capacitive gap and have no mechanical no thermal contacts. It allows to avoid using bellows and thus avoid the problem of heating and cooling. The windows have shields protecting shields against the electron, and this prevents the window ceramics from charging. Results of computer simulation of the new coupler are posted.

THPB098	Testing of 325 MHz Couplers at Test Stand in Resonance Mode	1376
	S. Kazakov, B.M. Hanna, O.V. Pronitchev Fermilab, Batavia, Illinois, USA
	The linear accelerator for the PIP-II program utilizes two types of 325 MHz Single Spoke resonator cavities: SSR-I and SSR-II. Operating power of SSR-II is about 17 kW and requires input couplers which can reliably work at power levels > 20 kW with full reflection at any reflected phase. Currently only one 10 kW RF amp is available for coupler testing. To increase testing power, a special resonance configuration were used. This configuration allows us to raise RF power approximately 3 times. The testing scheme and results are discussed in the paper.
