Spark discharge coupled laser multicharged ion source

Review of Scientific Instruments, 2015
A spark discharge is coupled to a laser multicharged ion source to enhance ion generation. The laser plasma triggers a spark discharge with electrodes located in front of the ablated target. For an aluminum target, the spark discharge results in significant enhancement in the generation of multicharged ions along with higher charge states than observed

Carbon multicharged ion generation from laser-spark ion source

Review of Scientific Instruments, 2019
Multicharged carbon ions are generated by using a laser-assisted spark-discharge ion source. A Q-switched Nd:YAG laser pulse (1064 nm, 7 ns, ≤ 4.5 × 109 W/cm2) focused onto the surface of a glassy carbon target results in its ablation. The spark-discharge (∼1.2 J energy, ∼1 µs duration) is initiated along the direction of the plume propagation between ...

Characterization of N-Terminal Acetylated α-Hemoglobin Stabilizing Protein (AHSP) by Top-Down High-Resolution Mass Spectrometry From Human Preterm Newborns Oral Fluid. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Alpha‐hemoglobin stabilizing protein (AHSP) is an erythroid‐specific protein forming a stable complex with free α‐hemoglobin, but not with β‐hemoglobin or hemoglobin A (α2β2), thus preventing harmful aggregation of α‐hemoglobin during normal erythroid cell development and avoiding its pro‐oxidant activity.

Encapsulated Non-Exchangeable Na⁺ Ions Determining the Upper Limit of Al Inclusion in FAU-A Multiscale Simulation. [PDF]

Angew Chem Int Ed Engl
DFT computation, AIMD simulations, machine learning, statistical analysis, and experimental characterization reveal that the upper limit of Al inclusion in FAU zeolite synthesized under hydrothermal conditions is determined by the encapsulated non‐exchangeable Na+ ions.

HR-MS Analysis of the Covalent Binding of Edaravone to 5-Formylpyrimidine Bases and a DNA Oligonucleotide Containing a 5-Formylcytidine Residue. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Edaravone (EDA) is a radical scavenger and an antioxidant drug approved to treat amyotrophic lateral sclerosis and used as a research tool to explore treatment of neurodegenerative diseases and cancers. It is also a reactive agent, known as PMP (1‐phenyl‐3‐methyl‐5‐pyrazolone), used for the analysis of polysaccharides composition ...

The ORNL ECR multicharged ion source [PDF]

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1985
Abstract A multicharged ion source based on electron cyclotron resonance (ECR) heating has been designed and built at ORNL. The ECR ion source, which is completely dedicated for atomic physics collisions studies, produces higher charge states and higher beam intensities than the present ORNL PIG multicharged ion source, and will thus permit study of ...

Two-cavity ECR source of multicharged ions

, 2020
The plasma density in ECR sources is limited by the cutoff plasma frequency, which prevents producing multicharged ions if one uses for plasma heating such low frequency microwaves as 2.45 GHz.
