Increasing the Brightness of Cold Ion Beams by Suppressing Disorder-Induced Heating with Rydberg Blockade

Area of Science:

• Atomic, Molecular, and Optical Physics
• Plasma Physics
• Beam Physics

Background:

• Disorder-induced heating can degrade the quality of cold ion bunches.
• Controlling correlations within ion systems is crucial for mitigating unwanted heating effects.
• Rydberg blockade is a phenomenon that influences inter-ion interactions.

Purpose of the Study:

• To quantify the suppression of disorder-induced heating in cold ion bunches.
• To investigate the impact of initial hard-sphere Rydberg blockade correlations on ion beam properties.
• To demonstrate the potential for enhanced beam quality using controlled ion interactions.

Main Methods:

• Development of a theoretical model for equilibrium coupling in ion systems.
• Incorporation of varying hard-sphere Rydberg blockade correlations into the model.
• Simulation and analysis of Coulomb-expanding cold ion bunches.

Main Results:

• The model quantifies the suppression of disorder-induced heating.
• Ion bunches with experimentally achievable blockade parameters exhibit a 2.6-fold reduction in emittance.
• These bunches show increased focusability and brightness compared to disordered bunches.

Conclusions:

• Suppression of disorder-induced heating is achievable with controlled Rydberg blockade.
• The developed model provides a pathway to engineer high-quality ion beams.
• This research is vital for advancing ultrafast, single-shot coherent diffractive imaging techniques.
