Abstract Within the effort on conceptual design of Divertor Test Tokamak (DTT) Neutral Beam Injector (NBI), Stray Field Shielding System (SFSS) for DTT NBI is under development, to suppress potentially harmful effects stray poloidal field from tokamak accelerated charged beam. Various possible solutions solve this problem are presented and compared, with a particular focus minimization procedur...

PURPOSE To describe a novel, small-incision, no-fold Descemet stripping automated endothelial keratoplasty (DSAEK) graft injector and to compare complications, visual acuity, and endothelial cell loss with a forceps technique. METHODS An Institutional Review Board-approved, interventional, nonrandomized, consecutive case series analysis of 175 eyes undergoing DSAEK for Fuchs dystrophy and bul...

Background and objectives: Essential oils (EOs) of medicinal herbs are prone to degradation by oxidation, heating, or light. Encapsulation of EOs can protect these fragile volatile natural products from degradation. Thymus vulgaris (thyme) is a well-known herb which has been used as food additive as well as medicine since ancient times. Electrospraying is a novel techn...

A novel 6 MeV hybrid photo-injector has been designed and constructed, based on a smaller-scale prototype previously built in UCLA’s Particle Beam Physics Laboratory. It commissioned at Ariel University Israel as an on-going collaboration between the two universities. This unique, new generation design provides radically simpler approach to RF feeding of gun/buncher system, leading much shorter...

The Laboratory for Elementary-Particle Physics, Cornell University, in collaboration with Jefferson Lab is exploring the potential of a Synchrotron Radiation User Facility based on a multi-GeV, low emittance, EnergyRecovery Linac (ERL) with a 100 mA CW beam[1]. The ERL injector will accelerate bunches from the electron source from 0.5 MeV to 5 MeV with minimal emittance growth. The injector and...

Abstract Purpose The physics design of the High Energy Photon Source (HEPS) was finished after many times iteration. Hereby, typical equilibrium electron beam parameters corresponding to proposed two baseline operation modes in HEPS are presented. Methods To compute beam, lattice parameters, RF and insertion devices (IDs) were determined first. Furthermore, it is more precise use full-current e...

At GSI heavy ion beams are accelerated by the UNIversal Linear ACcelerator UNILAC (see Fig. 1) and the heavy ion synchrotron SIS 18. Heavy ion beams are delivered to the High Current Injector (HSI) from two different ion source terminals: Penning type (PIG) sources for low and MUCIS/ MEVVA type sources for high beam intensities. An RFQ and two IH structures accelerate the ions from 2.2 keV/u up...
