A new high-precision current supply for magnets
A new, high-precision, low-ripple current power supply (CPS) for magnets, based on a combination of an SCR converter and a single transistor switched mode power supply (SMPS) is described. The loadExpand
Microstructure and properties of the compound layer obtained by pulsed plasma nitriding in steel gears
Abstract The crystalline structure profile of the compound layer obtained by pulsed plasma nitriding in steel gears is reported. The nitrogen depth profile obtained by Radio Frequency Glow DischargeExpand
A novel topology for the bending magnets power supply at LNLS
The synchrotron radiation source under construction at the LNLS in Brazil is composed of 12 bending magnets and 3 quadrupole families. A new topology for a high-performance DC current power supplyExpand
Influence of microstructure on the corrosion behavior of nitrocarburized AISI H13 tool steel obtained by pulsed DC plasma
Abstract The influence of microstructure on the corrosion behavior of pulsed plasma nitrocarburized AISI H13 tool steel in NaCl 0.9 wt/V % solution is reported. The samples were prepared withExpand
A comprehensive nitriding study by low energy ion beam implantation on stainless steel
In this paper we report nitriding studies of stainless steel 316 using a broad ion beam source. Experiments performed by changing the ion energy (0.2-1.5 KeV), ion current density (1.4-5.7 mAycm )Expand
LNLS Commissioning and Operation
The commissioning of the Brazilian synchrotron light source has begun, with the successful operation of the LINAC injector and the first thousands of turns of the coasting beam in the storage ring.Expand
Commissioning and operation of the Brazilian Synchrotron Light Source
The Brazilian National Synchrotron Light Laboratory, LNLS, operates a 1.37 GeV electron storage ring with a 120 MeV injector linac. Commissioning of the storage ring at low energy started on May 1996Expand
Power supplies for the LNLS magnets
Different types of power supplies that have been developed for the linac and VUV (vacuum ultraviolet) storage ring of LNLS (Laboratorio Nacional de Luz Sincrotron) are discussed. For the low-currentExpand
Effect of hydrogen and oxygen on stainless steel nitriding
The influence of hydrogen and oxygen on stainless steel implanted by nitrogen low-energy ions is systematically studied. It is shown that hydrogen intervenes moderately in the process only when theExpand
Operation of the LNLS storage ring RF system
The LNLS storage ring RF system operates at 476 MHz and delivers up to 60 kW CW into a single RF cavity. Injection and accumulation in the storage ring are done at low energy after which the beamExpand
