Pressures below 10 −10 torr can be maintained in large LHe cooled UHV systemsby increasing the available active cryosorbing surface area. Clean metal oxides (metal sponges) can provide the required surface area increase for higher adsorption capaci

The performance of superconducting RF cavities used in accelerators can be enhanced by detecting micro particles and inclusions which are the most serious source of performance degradation. These defects prevent the cavities from reaching the highest

There is an increasing demand for high beam current, high radio-frequency (RF) power S-band cavities in existing and new accelerator projects, such as for a study of future electron-ion collider (eRHIC) and a very brilliant, broadband, teraherz coher

In order to increase the protons energy up to 8 GeV in a driver Linac, the particles must be accelerated through various stages and three different power levels (25 kW, 100 kW and 210 kW) are required for the 325 MHz Fermilab Proton Driver couplers.

During the last year the e-e+-storage ring DORIS was changed from a 2 × 3,5 GeV double ring with 2 × 480 bunches circulating to a single ring single bunch machine with a maximum energy of 2 × 5.1 GeV. The modifications in the magnet structure and
