	The electron injector at IOTA/FAST is based on a 50MeV RF photoinjector and SRF 1.3 GHz cryomodule to accelerate beam up to 300 MeV. Photoinjector and Cryomodule (CM2) were commissioned separately. CM2 demonstrated world record accelerating gradient > 30MV/m in all cavities. Commissioning of the 50MeV RF photoinjector was successfully done recently. Results of commissioning, status and plans for IOTA/FAST are presented.

MOPLR015	Thermal-Mechanical Study of 3.9 GHz CW Coupler and Cavity for LCLS-II Project	171
	I.V. Gonin, E.R. Harms, T.N. Khabiboulline, N. Solyak, V.P. Yakovlev Fermilab, Batavia, Illinois, USA
	Third harmonic system was originally developed by Fermilab for FLASH facility at DESY and then was adopted and modified by INFN for the XFEL project [1-3]. In contrast to XFEL project, all cryomodules in LCLS-II project will operate in CW regime with higher RF average power for 1.3 GHz and 3.9 GHz cavities and couplers. Design of the cavity and fundamental power coupler has been modified to satisfy LCLS-II requirements. In this paper we discuss the results of COMSOL thermal and mechanical analysis of the 3.9 GHz coupler and cavity to verify proposed modifica-tion of the design. For the dressed cavity we present simulations of Lorentz force detuning, helium pressure sensitivity df/dP and major mechanical resonances.
