We describe and benchmark a new quantum charge-coupled device (QCCD) trapped-ion computer based on linear trap with periodic boundary conditions, which resembles race track. The system successfully incorporates several technologies crucial to future scalability, including electrode broadcasting, multi-layer RF routing, magneto-optical (MOT) loading, while maintaining, in some cases exceeding, the gate fidelities of previous QCCD systems. is initially operated 32 qubits, but upgrades will allow for more. performance primitive operations, an average state preparation measurement error 1.6(1)$\times 10^{-3}$, single-qubit infidelity $2.5(3)\times 10^{-5}$, two-qubit $1.84(5)\times 10^{-3}$. system-level processor assessed mirror benchmarking, cross-entropy volume $\mathrm{QV}=2^{16}$, creation 32-qubit entanglement GHZ state. also tested application benchmarks Hamiltonian simulation, QAOA, correction repetition code, dynamics simulations using qubit reuse. discuss aimed at adding more qubits capabilities.
