	A. Saini, V.V. Kapin, N. Solyak Fermilab, Batavia, Illinois, USA
	International Linear collider (ILC) is a proposed accelerator facility which is primarily based on two 11-km long superconducting main linacs. In this paper we present recent updates on the main linac design and discuss changes made in order to meet specification outlined in the technical design report (TDR).

WE1A01	PIP-II Injector Test: Challenges and Status	641
	P. Derwent, J.-P. Carneiro, J.P. Edelen, V.A. Lebedev, L.R. Prost, A. Saini, A.V. Shemyakin, J. Steimel Fermilab, Batavia, Illinois, USA
	The Proton Improvement Plan II (PIP-II) at Fermilab is a program of upgrades to the injection complex. At its core is the design and construction of a CW-compatible, pulsed H⁻ superconducting RF linac. To validate the concept of the front-end of such machine, a test accelerator known as PXIE is under construction. It includes a 10 mA DC, 30 keV H⁻ ion source, a 2 m-long Low Energy Beam Transport (LEBT), a 2.1 MeV CW RFQ, followed by a Medium Energy Beam Transport (MEBT) that feeds the first of 2 cryomodules increasing the beam energy to about 25 MeV, and a High Energy Beam Transport section (HEBT) that takes the beam to a dump. The ion source, LEBT, RFQ, and initial version of the MEBT have been built, installed, and commissioned. This report presents the overall status of the PXIE warm front end, including results of the beam commissioning through the installed components, and progress with SRF cryomodules and other systems.

THPRC014	RF Losses in 1.3 GHz Cryomodule of The LCLS-II Superconducting CW Linac	798
	A. Saini, A. Lunin, N. Solyak, A.I. Sukhanov, V.P. Yakovlev Fermilab, Batavia, Illinois, USA
	The Linac Coherent Light Source (LCLS) is an x-ray free electron laser facility. The proposed upgrade of the LCLS facility is based on construction of a new 4 GeV superconducting (SC) linac that will operate in continuous wave (CW) mode. The major infrastructure investments and the operating cost of a SC CW linac are outlined by its cryogenic requirements. Thus, a detail understanding of RF losses in the cryogenic environment is critical for the entire project. In this paper we review RF losses in a 1.3 GHz accelerating cryomodule of the LCLS-II linac. RF losses due to various sources such untrapped higher order modes (HOMs), resonant losses etc. are addressed and presented here.

THPRC026	Optical Design of the PI-Test MEBT Beam Scraping System	827
	A. Saini, A.V. Shemyakin Fermilab, Batavia, Illinois, USA
	PI-Test [1] is an accelerator facility under construction at Fermilab that will provide a platform to demonstrate critical technologies and concept of front-end of the PIP-II superconducting radio frequency (SRF) linac. It will be capable to accelerate an H⁻ ion beam with average current of 2 mA up to 25 MeV in continuous wave (CW) regime. To protect the SRF components from beam irradiation, the Medium Energy Beam Transport (MEBT) section of PI-Test includes an elaborated beam scraping system. It consists of four assemblies spread along the MEBT, with each assembly composed of four radiation-cooled, electrically isolated plates that can be moved into the beam in horizontal and vertical direction. The primary objectives of scraping system are to intercept particles with large transverse action and to protect the beamline elements and SRF linac in case of errors with beam focusing or steering. In this paper we formulate requirements for the scraping system and discuss factors affecting its efficiency. An optical design compatible with PI-Test MEBT is also presented.
