An electrostatic autoresonant ion trap mass spectrometer.
A new method for ion extraction from an anharmonic electrostatic trap is introduced. Anharmonicity is a common feature of electrostatic traps which can be used for small scale spatial confinement of ions, and this feature is also necessary for autoresonant ion extraction. With the aid of ion trajectory simulations, novel autoresonant trap mass spectrometers (ART-MSs) have been designed based on...
متن کاملContinuous loading of an electrostatic trap for polar molecules.
A continuously operated electrostatic trap for polar molecules is demonstrated. The trap has a volume of approximately 0.6 cm3 and holds molecules with a positive Stark shift. With deuterated ammonia from a quadrupole velocity filter, a trap density of approximately 10(8) cm(-3) is achieved with an average lifetime of 130 ms and a motional temperature of approximately 300 mK. The trap offers go...
متن کاملStorage and injection of charged particles in an electrostatic trap
2014 Ion confinement in an purely electrostatic ion trap is investigated. The trap consists of two concentric cylinders maintained at a potential difference and two electrically insulated end plates. If the length of the trap is long compared with the radial dimension of the trap, the radial potential distribution is practically logarithmic. The domain of ion confinement is derived by comparing...
متن کاملElectrostatic beams from tailored plasmas in a Penning–Malmberg trap
In recent work, a technique was developed to extract high quality beams from single-component plasmas confined in a Penning–Malmberg trap in a 4.8 T magnetic field. In this paper, a procedure is developed to extract these beams from the confining magnetic field and then focus them to create especially tailored electrostatic beams. Electron beams are extracted from the field in two stages: they ...
متن کاملNote: Electrostatic beams from a 5 T Penning-Malmberg trap.
A procedure is described to extract beams from specially tailored electron plasmas in a Penning-Malmberg trap in a 4.8 T field. Transport to 1 mT is followed by extraction from the magnetic field and electrostatic focusing. Potential applications to positron beams are discussed.
