Modification of the Stability Regions in Stretched Paul Ion Trap by Damping Force [PDF]
مجله علوم و فنون هستهای, 2017 With the change of an ion trap geometrical shape, ring and end-cap electrodes, and also damping force effects, the first and second stability regions are studied in a stretched Paul ion trap.

Thermometry in a Multipole Ion Trap
Applied Sciences, 2020 We present a characterization of the ions’ translational energy distribution in a multipole ion trap. A linear mapping between the energy distribution of the trapped ions onto the ions’ time-of-flight (TOF) to a detector is demonstrated.

Shortcuts to adiabaticity for an ion in a rotating radially-tight trap
New Journal of Physics, 2016 We engineer the fast rotation of an effectively one-dimensional ion trap for a predetermined rotation angle and time, avoiding the final excitation of the trapped ion.

Stability study of intense hadron bunches in linear accelerators using a Paul ion trap
Physical Review Accelerators and Beams, 2022 The collective behavior of an ion cloud confined in a linear Paul trap is physically almost equivalent to that of a relativistic beam traveling in a particle accelerator.

Loading a Paul Trap: Densities, Capacities, and Scaling in the Saturation Regime
Atoms, 2021 Providing ideal conditions for the study of ion-neutral collisions, we investigate here the properties of the saturated, steady state of a three-dimensional Paul trap, loaded from a magneto-optic trap.

Effects of collisional cooling on ion detection in a quadrupole ion trap mass spectrometer
, 2011 The effects of collisional cooling on the storage and detection of ions in a quadrupole ion trap mass spectrometer are examined. Four parameters that affect the storage of ions are evaluated: the pressure of the buffer gas: the qz value which establishes

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

, 2009 This paper describes the formation of protonated molecules ([M + H]+) and adduct ions by self-ion-molecule reactions (SIMR) during collisionally activated decomposition (CAD) of methyne addition ions ([M + CH]+) produced from chemical ionization (CI) or ...
