چکیده
Free electron lasers (FELs) have until now been limited to the infrared, visible and near UV part of the electromagnetic spectrum . Recent progress in FEL physics and technology is changing this situation, and an effort is now under way to design and build FELs operating at wavelengths shorter than 100 nm . Three main avenues are being followed to reach this goal : FELs oscillators based on storage rings ; FEL oscillators based on linacs ; harmonic generation ; linac based FELs operating in the Self Amplified Spontaneous Emission (SASE) mode . The last approach has been followed by a SLACUCLA-LBL-LLNL collaboration [1] to design a 2 to 4 nm soft X-ray FEL utilizing the existing SLAC linac and the possibility it offers to produce high brightness electron beams of energy up to 50 GeV. The main characteristics of this soft X-ray FEL are given in Tables 1 and 2. A SASE FEL avoids the use of optical cavities by operating as a single pass, high gain amplifier starting from spontaneous radiation [2,3]. In the soft X-ray region mirrors are lossy and subject to damage from

متن کاملComputing Definite Logic Programs by Partial Instantiation
Kagan, V., A. Nerode and V.S. Subrahmanian, Computing definite logic programs by partial instantiation, Annals of Pure and Applied Logic 67 (1994) 161-182. Query processing in ground definite deductive databases is known to correspond precisely to a linear programming problem. However, the “groundedness” requirement is a huge drawback to using linear programming techniques for logic program com...
متن کاملBackground-adaptive dual-energy-window correction for Compton scattering in SPECT
Detection of gamma rays which Compton scatter within a patient but are still within the photopeak window of the Anger camera leads to inaccuracies in quantification of radioactivity from nuclear-medicine images. With the dual-energy-window correction method and a single (universal) scatter multiplier, the activity error is relatively large when there is tissue background with a large range of v...

متن کاملAn experimental and Monte Carlo investigation of the R1408 Hamamatsu 8-inch photomultiplier tube and associated concentrator to be used in the Sudbury Neutrino Observatory
The Sudbury Neutrino Observatory will use an array of 9500 Hamamatsu R1480 8-in. photomultiplier tubes and their associated concentrators to detect Cherenkov light. This paper describes an experimental investigation of the photomultiplier tubes and their concentrators, together with work done to model the angular and wavelength response. Good agreement is achieved. 0168~9002/96/$15.00 Copyright...
