Adiabaticity of emittance exchange due to crossing of the coupling resonance

Physical Review Accelerators and Beams, 2021
In circular accelerators, crossing the linear coupling resonance induces the exchange of the transverse emittances, provided the process is adiabatic. This has been considered in some previous works, where the description of the phenomenon has been laid ...

Theoretical study on the application of isothermal compression technology in vapor‐compression refrigeration systems with an isothermal piston

Energy Science & Engineering, 2021
Vapor‐compression refrigeration systems are widely used in refrigeration equipment. Theoretically, the process is typically divided into two isobaric processes: an adiabatic isentropic compression process and adiabatic isentropic throttling process.
