Abstract

We show, through modeling and simulation, that it is feasible to construct a storage ring that will store dense bunches of strong-field-seeking polar molecules at 30 m/s (kinetic energy of 2K) and hold them, for several minutes, against losses due to defocusing, oscillations, and diffusion. The ring, 3 m in diameter, has straight sections that afford access to the stored molecules and a lattice structure that may be adapted for evaporative cooling. Simulation is done using a newly-developed code that tracks the particles, in time, through 400 turns; it accounts for longitudinal velocity changes as a function of external electric field, focusing and deflection nonlinearities, and the effects of gravity. An injector, decelerator, and source are included and intensities are calculated.

Stable, High-Charge, Laser-Driven VHEE Beams for Preclinical Applications

Laser-driven plasma accelerators (LPAs) are promising sources of very-high-energy-electron (VHEE) beams for medical applications, but increasing charge per pulse while maintaining pointing stability remains challenging. We demonstrate laser-accelerated beams with total charge per pulse reaching (559 $\pm$ 56) pC using an 80 TW laser system. The spectra have a dominant component at 40-60 MeV and a high-energy tail extending to approximately 200 MeV. Pointing jitter measured in air at the irradiation target plane reaches as low as 0.7 mrad. The beams were used for VHEE irradiation experiments involving a 10 mm region of interest through a 40 mm depth at 400 $\pm$ 20 mGy/pulse. Spectral reproducibility is quantified over fixed-setting shot sequences. Particle-in-cell simulations produce a peak-and-tail spectrum through acceleration in successive bubbles associated with a strongly modified plasma wake, providing a plausible mechanism for maintaining substantial accelerated charge despite strong beam loading. Dose-weighted time-of-flight calculations indicate an effective pulse dose rate of $10^{12}$ Gy/s and average dose rates of tens of Gy/min. These results establish an LPA operating regime relevant to preclinical VHEE irradiation.

Quantum transport of vortex electrons in bending magnets and circular accelerators

Controlling the sizes and phase structure of single-particle wave packets in accelerators remains an experimental challenge and requires understanding how bending magnets transform these states. An important example is transporting relativistic vortex electrons through the magnets to a collision point while keeping a narrow orbital-angular-momentum (OAM) distribution. We derive an effective Hamiltonian that accounts for the packet acceleration, employ it to obtain a generalized BMT-like equation, match the electron state at both magnet boundaries, and calculate the mean OAM and its variance. A half turn can reverse the mean OAM relative to the momentum while broadening its distribution, so recovering the mean does not ensure state recovery. We identify windows in packet sizes and bend angles for a small OAM spread and show that weak bends can produce narrow distributions with the mean OAM tilted relative to the momentum, making these states candidates for spatiotemporal vortices. For a few MeV electrons, we propose to use half-turn magnets that leave the mean OAM nearly antiparallel to the momentum while keeping its distribution narrow. For a circular orbit in a uniform field, the OAM variance after the exit grows as $N^2$ over $N$ turns, favoring linear accelerators, such as LINAC at JINR, for first experiments in MeV range.

Fast prediction of electron-beam parameters using transfer maps and machine learning in a digital model of a MeV $γγ$ collider

Tuning the electron beam of a MeV-scale $γγ$ collider, first in the design and later in a digital twin of the machine, requires the beam parameters at the interaction point (IP) for many injector states. Start-to-end particle tracking is too slow for this and needs the full particle distribution, which an operating machine cannot measure. We address this problem for the 200-MeV transport line of the collider with two fast predictors. For design, second-order transfer maps from the transport entrance to the IP are applied to every particle. For a digital twin, an extremely-randomized-trees (ExtraTrees) model predicts the IP parameters from the means and rms widths of the beam at the transport entrance. On 89 held-out start-to-end simulations, the map predictor reproduces Elegant tracking for the mean energy, momentum spread, bunch length, transverse rms sizes and normalized emittances with coefficients of determination ($R^2$) of 0.97--1.00 and is ten times faster. The ExtraTrees model reaches an average $R^2$ of 0.88, compared with 0.58 when the injector settings are used as input, and performs similarly with eleven inputs that can be measured or reconstructed. Under a 2% input perturbation, the average $R^2$ of the six parameters other than the mean energy decreases only from 0.917 to 0.895, whereas the mean energy requires an accurate momentum calibration. The two predictors provide the IP-beam evaluation for the collider design and the prediction layer of a future digital twin.
