POSITIVE AND NEGATIVE ION MASS SPECTRA OF RING - SUBSTITUTED NITROBENZENES
The 70 ev positive and negative ion mass spectra of ring-substituted nitrobenzenes were studied. The influence of the substituent group on the fragmentation modes of the molecular ions is discussed. The effect of pressure in the formation of negative ions was also studied. As expected, the ratio of fragment ions to negative molecular ions decreased with increasing pressure in ion source.

متن کاملReview of Negative Hydrogen Ion Sources High Brightness/high Current
Due to the development of reliable H ion sources, charge-exchange injection into circular accelerators has become routine. This paper reviews recent developments in negative hydrogen ion sources. The underlying physics, operating parameters and beam characteristics of selected sources will be described and compared. Figure 1: History of duoplasmatron and surface source development.
متن کاملOrganic negative electrode materials for Li-ion and Na-ion batteries
This thesis work comprises work on novel organic materials for Liand Nabatteries, involving synthesis, characterization and battery fabrication and performance. First, a method for improving the performance of a previously reported Li-ion battery material (lithium benzenediacrylate) is presented. It is demonstrated that applying freeze drying in combination with carbon coating in the liquid sta...
متن کاملEffect of Coulomb collision on the negative ion extraction mechanism in negative ion sources.
To improve the H(-) ion beam optics, it is necessary to understand the energy relaxation process of surface produced H(-) ions in the extraction region of Cs seeded H(-) ion sources. Coulomb collisions of charged particles have been introduced to the 2D3V-PIC (two dimension in real space and three dimension in velocity space particle-in-cell) model for the H(-) extraction by using the binary co...
