Chinese philosopher Chuang Tzu, said “newborn calves are not afraid of tigers”, this quote may describe my 5 year adventure. “Being as a newborn calf” makes me to be in trouble but also helps me to get out. What is PhD? In the beginning, I didn’t make myself this question seriously. As a newborn calf, I believed PhD as a chance and thought my PhD would innovate the research field. After about two years of turmoil, the question came again, what is PhD? Istartedto think PhD was about solving a unanswered question. My story was nearly ended there at that moment, but I was a lucky man, since I met with Daniel López Bruna (Daniel) and María Antonia Ochando García (Marian), and later on they became my Thesis directors.

  • Microwave Power Coupling with Electron Cyclotron Resonance Plasma Using Langmuir Probe
    PRAMANA c Indian Academy of Sciences Vol. 81, No. 1 — journal of July 2013 physics pp. 157–167 Microwave power coupling with electron cyclotron resonance plasma using Langmuir probe SKJAIN∗, V K SENECHA, P A NAIK, P R HANNURKAR and S C JOSHI Raja Ramanna Centre for Advanced Technology, Indore 452 013, India ∗Corresponding author. E-mail: [email protected] MS received 14 April 2012; revised 16 January 2013; accepted 26 February 2013 Abstract. Electron cyclotron resonance (ECR) plasma was produced at 2.45 GHz using 200– 750 W microwave power. The plasma was produced from argon gas at a pressure of 2 × 10−4 mbar. Three water-cooled solenoid coils were used to satisfy the ECR resonant conditions inside the plasma chamber. The basic parameters of plasma, such as electron density, electron temperature, floating potential, and plasma potential, were evaluated using the current–voltage curve using a Langmuir probe. The effect of microwave power coupling to the plasma was studied by varying the microwave power. It was observed that the optimum coupling to the plasma was obtained for ∼ 600 W microwave power with an average electron density of ∼ 6 × 1011 cm−3 and average electron temperature of ∼ 9eV. Keywords. Electron cyclotron resonance plasma, Langmuir probe, electron density, electron temperature. PACS Nos 52.50.Dg; 52.70.–m; 52.50.Sw 1. Introduction The electron cyclotron resonance (ECR) plasma is an established source for delivering high current, high brightness, stable ion beam, with significantly higher lifetime of the source. Such a source has been widely used for producing singly and multiply charged ion beams of low to high Z elements [1–3], for research in materials sciences, atomic and molecular physics, and as an accelerator injector [4,5].

  • 1 Input from the US Stellarator Research Community to the FESAC
    Input from the US Stellarator Research Community to the FESAC Panel on Toroidal Alternates June 2008 Abstract International research carried out over the past 5 decades has steadily validated the ability of the stellarator magnetic configuration to confine high performance, macroscopically quiescent plasmas with inherent steady-state capability. Sharing many of the same physics characteristics as tokamaks, stellarators attain similar plasma parameters and figures of merit to comparably-sized tokamaks. In conjunction with ongoing tokamak research in the burning plasma era, work on stellarators over the next twenty years is intended to develop the stellarator concept to be ready to proceed to a DEMO-scale experiment. Apart from the plasma-wall interaction and materials problems that confront all steady-state toroidal reactor concepts, the stellarator does not exhibit a clear scientific ‘show-stopper’ that would preclude it from successfully confining a burning DT plasma. The main challenges confronting the stellarator concept specifically are to validate that our understanding of 3D plasma confinement physics extends to fusion relevant plasma parameters and to systematically develop system designs that accommodate the complexity of the highly-shaped, three-dimensional plasma configuration and the magnet coils that produce it. The progress of the stellarator toward its DEMO goal will be facilitated to a great extent if the stellarator coils can be simplified while still producing the magnetic configuration required for good confinement, stability, and fusion gain. To do so will require improved understanding of the behavior of existing and future stellarator plasmas coupled with the ability to provide the necessary shaping of the 3-D magnetic flux surfaces with an efficiently-engineered set of coils.

The proposal is to calculate the excitation temperature (Texc), electronic temperature (Te) and electron density (ne) for several plasma techniques used in the growth of thin films. Some of these tech- niques include magnetron sputtering and arc discharges. Initially, some fundamental physical principles that support the Optical Emission Spec- troscopy (OES) technique are described; then, some rules to consider dur- ing the spectral analysis to avoid ambiguities are listed. Finally, some of the more frequently used spectroscopic methods for determining the phy- sical properties of plasma are described.

  • 10 Frontiers in Low Temperature Plasma Diagnostics Book of Abstracts
    10 th Frontiers in Low Temperature Plasma Diagnostics April 28 th – May 2nd 2013 Rolduc, Kerkrade, The Netherlands Book of Abstracts We wish to express a warm welcome to all attendees to the 10 th Workshop on Frontiers in Low Temperature Plasma Diagnostics (FLTPD) in the historic Conference Centre Rolduc, Kerkrade, the Netherlands from 28 th of April to 2 nd of May. The Workshop is the continuation of a very successful biennial series that began in 1995 at Les Houches (France). It is co- organized by the Eindhoven University of Technology (TU/e) and the Dutch Institute for Fundamental Energy Research (DIFFER), two institutions which are strongly involved in the plasma physics and technology research in the Netherlands. The workshop offers the opportunity to present recent results on plasma diagnostics. The aim of the workshop is to bring together experts in the field of low temperature plasma diagnostics. It is an important and fruitful opportunity for the new generation of plasma scientists to share and discuss the knowledge of these diagnostics with the leading scientists of the field. To facilitate interaction among participants free time is scheduled on Monday and Tuesday afternoon. In line with the nine previous meetings, the program consists of expert presentations from 10 invited speakers, 16 topical speakers and 57 posters. Several companies will exhibit their products. The excursion on Wednesday is to the historical city of Aix-la-Chapelle / Aachen where a guided tour of the cathedral or the city is arranged. The conference dinner is on Wednesday evening. During the conference dinner, two prizes will be awarded for the best poster and the best oral presentation for which only students are eligible.
