	Funding: U.S. Department of Energy DOE SBIR Phase I Project DE-SC0020934 As part of the MACH-B (Multipole Accelerator Codes for Hadron Beams) project, we have developed a Fast Multipole Method (FMM*)-based tool for higher fidelity modeling of particle accelerators for high-energy physics within Fermilab’s Synergia simulation package. We present results from our implementations with a focus on studying the difference between tune depression estimates obtained using PIC codes for computing the particle interactions and those obtained using FMM-based algorithms integrated within Synergia. In simulating the self-interactions and macroparticle actions necessary for accurate simulations, we present a newly-developed kernel inside of a kernel-independent FMM in which near-field kernels are modified to incorporate smoothing while still maintaining consistency at the boundary of the far-field regime. Each simulation relies on Synergia with one major difference: the way in which particles interactions were computed. Specifically, following our integration of the FMM into Synergia, changes between PIC-based computations and FMM-based computations are made by changing only the method for near-field (and self) particle interactions. * J.

	Within the framework of technology studies on future accelerators, CERN has initiated a five-years R&D project aimed at the evaluation of the REBCO (Rare Earth Barium Copper Oxide) High Temperature Superconductors (HTS). The study covers a number of areas from material science to electromechanical properties. The REBCO high-field tape will be tested on different HTS magnet prototypes, such as HDMS (HTS Demonstrator Magnet for Space), GaToroid (hadron therapy Gantry based on a toroidal magnetic field) and other smaller coils that will be fabricated to study the tape’s potential. To assemble the HTS coils, a new automatic winding station has been designed and constructed at CERN. A touch panel combined with an embedded controller running software developed in-house provides a sophisticated, yet intuitive and user-friendly system aimed at maintaining perfect coil winding conditions. In this paper, we describe the mechanical choices and techniques used to control the seven HTS spool tapes and the winding machine. We also present the analysis of several coils already produced.

THPV032	The Demonstrator of the HL-LHC ATLAS Tile Calorimeter	electron, electronics, detector, high-voltage	935
	P. Tsotskolauri Tbilisi State University, T’bilisi, Georgia
	The High Luminosity Large Hadron Collider (HL-LHC) has motivated R&D to upgrade the ATLAS Tile Calorimeter. The new system consists on an optimized analogue design engineered with selected radiation-tolerant COTS and redundancy layers to avoid single points of failure. The design will provide better timing, improved energy resolution, lower noise and less sensitivity to out-of-time pileup. Multiple types of FPGAs, CERN custom rad-hard ASICs (GBTx), and multi-Gbps optical links are used to distribute LHC timing, read out fully digital data of the whole TileCal, transmit timing and calibrated energy per cell to the Trigger system at 40 MHz, and provide triggered data at 1 MHz. To test the upgraded electronics in real ATLAS conditions, a hybrid demonstrator prototype module containing the new calorimeter module electronics, but still compatible with TileCal’s legacy system was tested in ATLAS during 2019-2021. An upgraded version of the demonstrator with finalized HL-LHC electronics is being assembled to be tested in testbeam campaigns at the Super Proton Syncrotron (SPS) at CERN. We present current status and results for the different tests done with the upgraded demonstrator system. Presented on behalf of the ATLAS Tile Calorimeter System
