	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.

	The Low Level Radio Frequency (LLRF) system is an important part of a Spallation Source facility as ESS. LLRF is commonly used with many different setups depending on the aim: preparation, calibration, conditioning, commission and others. These different setups are strongly connected to another important system on accelerators: the Timing System. This proceeding presents how at ESS we implemented the integration between LLRF and Timing systems on the control system scope. The integration of these two systems provides different and important features as: allow different ways to trigger the RF system (synced or not to other systems), define how the RF output will be defined (based on the features of the expected beam), re-configure LLRF depending on the timing setup and more. This integration was developed on both ends, LLRF and timing, and is mostly concentrated on the control system layer based on EPICS. Dealing with the different scenarios, synchronicity and considering all the software, hardware and firmware involved are some of the challenges of this integration. The result of this work was used during the ESS accelerator commissioning in 2022 and will be used on next ESS accelerator commissioning in 2023.
