	Funding: National Nuclear Security Administration (NNSA) This work presents a review of the shift in tuning methods employed at the Los Alamos Neutron Science Center (LANSCE). We explore the tuning categories and methods employed in four key sections of the accelerator, namely the Low-Energy Beam Transport (LEBT), the Drift Tube Linac (DTL), the side-Coupled Cavity Linac (CCL), and the High-Energy Beam Transport (HEBT). The study additionally presents the findings of employing novel software tools and algorithms to enhance each domain’s beam quality and performance. This study showcases the efficacy of integrating model-driven and model-independent tuning techniques, along with acceptance and adaptive tuning strategies, to enhance the optimization of beam delivery to experimental facilities. The research additionally addresses the prospective strategies for augmenting the control system and diagnostics of LANSCE. R.W. Garnett, J. Phys.: Conf. Ser. 1021 012001 A. Scheinker, Rev. ST Accel.

TUPDP080	Automated Procedure for Conditioning of Normal Conducting Accelerator Cavities	cavity, controls, linac, vacuum	699

	Radio frequency (RF) conditioning is an essential stage during the preparation of particle accelerator cavities for operation. During this process the cavity field is gradually increased to the nominal parameters enabling the outgassing of the cavity and the elimination of surface defects through electrical arcing. However, this process can be time-consuming and labor-intensive, requiring skilled operators to carefully adjust the RF parameters. This proceeding presents the software tools for the development of an automatized EPICS control application with the aim to accelerate and introduce flexibility to the conditioning process. The results from the conditioning process of the ESS Radio-Frequency Quadrupole (RFQ) and the parallel conditioning of Drift-Tube Linac (DTL) tanks will be presented demonstrating the potential to save considerable time and resources in future RF conditioning campaigns.

THPDP030	ESS Drift Tube Linac Control System Commissioning: Results and Lessons Learned	controls, EPICS, hardware, site	1377
	M. Montis, L. Antoniazzi, A. Baldo, M.G. Giacchini INFN/LNL, Legnaro (PD), Italy A. Rizzo ESS, Lund, Sweden
	European Spallation Source (ESS) will be a neutron source using proton beam Linac of expected 5MW beam power. Designed and implemented by INFN-LNL, the Drift Tube Linac (DTL) control system is based on EPICS framework as indicated by the Project Requirements. This document aims to describe the results of the first part of the control system commissioning stage in 2022, where INFN and ESS teams were involved in the final tests on site. This phase was the first step toward a complete de-ployment of the control system, where the installation was composed by three sequential stages, according to the apparatus commissioning schedule. In this scenario, the firsts Site Acceptance Test (SAT) and Site Integrated Test (SIT) were crucial, and their results were the mile-stones for the other stages: the lessons learned can be important to speed up the future integration, calibration, and tuning of such a complex control system.
