23rd IUVSTA Workshop on
GETTERING MATERIALS: PRINCIPLES AND USES


(CLICK HERE)

SCOPE

To bring together highly qualified researchers currently working with or on gettering materials from differing points of view, and thus fostering synergetic exchange between areas and domains which usually do not directly interact. Physical and chemical getters will be considered. The Workshop is organized by the International Union for Vacuum Science, Technique, and Applications (IUVSTA). The invited speakers will encompass:

  • Vacuum metallurgists experts in preparing chemical getters and tailoring their properties.
  • Vacuum scientists experts in evaluating macroscopic properties of getters such as pumping speed and capacity as a function of external variables.
  • Surface scientists experts in evaluating and modeling the surface and near-surface properties of gettering materials as a function of different physical and chemical parameters such as temperature, gas exposure, and surface preparation.
  • Scientists experts of specific applications of gettering materials in science and technology (e.g. getters for hydrogen storage, ultra purification of gases, etc.).

TOPICS

  • Metallurgy of non evaporable gettering materials (NEG's)
  • Evaluation of vacuum properties of getters
  • Ultra purification of gases via NEG's
  • Surface and near-surface characterization of gettering materials
  • Thermodynamics and kinetics of the getters' behavior
  • Role of defects
  • Adsorption: chemical versus physical
  • Molecule dissociation
  • Indiffusion, desorption, formation of surface compounds
  • Hydrogen storage and hydrides in NEG's
  • New and exotic applications of gettering materials
  • Present applications of gettering materials
  • Theory of gettering
  • Catalysis
  • Outgassing phenomena

 

FORMAT: The Workshop will be organized on the basis of invited talks. Contributed papers will be selected after abstract submission. A poster session will be organized as well. A limited number of registrations will be accepted.

DATE: June 5-10, 1999

VENUE: Bonassola (Italy). The Workshop will be held in the St. Erasmo's Oratory Conference Center located in Bonassola. The site is on the beautiful Mediterranean rocky coast of Liguria. Bonassola is about 70 km far from Genoa (Genova).

TRAVEL: Bonassola can be reached by train or car. Train connections are from Milan and Genoa where international airports are located

SOCIAL EVENTS: Excursions to the Le Cinque Terre by boat are planned. People booking half board will enjoy a beach party. Otherwise an additional charge will be required.
