TUC2C2	Evaluating PyORBIT as Unified Simulation Tool for Beam-Dynamics Modeling of the ESS Linac	lattice, simulation, DTL, space-charge	102

	The design of the ESS proton linac was supported by the simulation code TraceWin, a closed-source commercial software for accurate multiparticle simulations. Conversely, the high-level physics applications used for beam commissioning and machine tuning rely on the Open XAL framework and its online model for fast envelope simulations. In this paper, we evaluate PyORBIT for both online modeling of the linac for machine commissioning and tuning as well as for more accurate offline simulations for beam-dynamics studies. We present the modifications done to the code to adapt it to this use case, namely porting the code to Python 3, adding an envelope tracker, and integrating with the EPICS control systems. Finally, we show the results of benchmarking PyORBIT against our current modeling tools.

THBP57	A Novel RF Power Source for the ESS-Bilbao Ion Source	controls, ion-source, proton, klystron	621

	This paper presents the improvements in the ESS Bilbao Proton Ion Source by replacing the amplified radio frequency (RF) pulse of a Klystron-based amplification system using a Solid-State Power Amplifier (SSPA). This new amplification system is based on a 1kW SSPA (2.7 GHz), a Compact-RIO (cRIO) device, a voltage-controlled RF attenuator and auxiliary electronics. The Experimental Physics and Industrial Control System (EPICS) serves as distributed control system (DCS) for controlling and monitoring the data required to achieve a 1.5 ms flat and stable pulse at repetition rate of 14 Hz. The following lines describe the structural and control system changes done in the ion source due to the addition of the SSPA-based amplification system, along with the results of the proton beam extraction tests that demonstrate how this system can serve as a viable substitute for the Klystron-based amplification system.
