AbstractAbstract
[en] This bibliography covers the field of electrical discharges in vacuum, comprising both electrical breakdown in vacuum and vacuum arcs. A breif review section lists some review papers which would be helpful to the novice in this field. The bulk of the paper consists of bibliographic listings, arranged by year of publication and within each year, alphabetically by first author. An author index refers one to all papers authored or coauthored by a particular person. There are 2032 papers listed through December 1978

AbstractAbstract
[en] The 'BESSY' high current electron storage ring, build in Berlin, is one of the typical high power UV-light sources. As much duty time as possible will be wanted, when the machine will be operating. A bakeable, stainless 10-8 steel vacuum system is therefore provided to give adequate beam life time with .10-8 mbar average presure in presence of a 500 mA electron beam after fast start up of the system. Prepumping will be done by turbo-molecular-pumps with oil-free operation. The operating pumping system consists of 400 1.sec-1 lumped sputter ion pumps and of special designed 'hole plate' integrated sputter ion pumps for high field application

AbstractAbstract
[en] The UHV system of PETRA is divided by gate valves into 30 separate sections of about 100 m length, each provided with a turbomolecular pump and a mass spectrometer. The vacuum chambers in the arcs are made from aluminium extrusions, and the straight sections from stainless steel. The installed mean pumping speed is about 110 l/s/m. The discharge current of the sputter-ion pumps is used to monitor the pressure of the system. All active vacuum components such as pumps, spectrometers, valves, turbomolecular pumps etc., are computer controlled over distances of the order of 1 km. A base pressure lower than 1x10-9 mbar is obtained without bake-out. Also an Argon glow discharge cleaning in situ is not needed because of the self cleaning effect of the synchrotron light emitted by the circulating electrons. Pressure increases of about of 1x10-10 mbar per stored mA and beam life times of the order of 20 hours have been achieved up to energies of 10 GeV

AbstractAbstract
[en] Clean, ultra-high vacuum systems are necessary in more and more experiments in modern physics. Devices implied in building such systems, as: UHV all-metal valves, getter-ion pumps and UHV measurements, control and regulation units are presented. The technical characteristics of the devices presented are in accordance with those of international standards. (Author)

AbstractAbstract
[en] This paper is described on the out line of the vacuum system for the cyclotron at the Research Center for Nuclear Physics (RCNP). The cyclotron accelerates protons to the energy of 75 MeV, and the K valve for heavy ions is 120 q2/A. The gas pressure in the vacuum system must be lower than 10-6 Torr. The capacity of the vacuum system has enough margin for the volume of the whole system. Special attention has been paid for the material used for the system. The maximum pump speed is 44000 l/sec. After four years operation, any change in the amount of diffusion oil and oil color has not been seen. The gas pressure at the baffles is 4.5 x 10-7 Torr. The gas to be accelerated is fed through a hole of magnet yoke. Expensive gas such as He-3 is collected and recirculated after purification. A polarized ion source is set at the upper part of the cyclotron. The amount of gas-flow for the polarized ion source is large, therefore several diffusion pumps are used for this ion source. The evacuation of beam course is made with molecular pumps, since it is necessary to keep clean the surfaces of target samples and detectors. All the system can be remotely controlled from the control room. (Kato, T.)
