چکیده
COSY 5.0 is a new computer code for the design of corpuscular optical systems based on the principle of transfer matrices . The particle optical calculations include all image aberrations through fifth order. COSY 5.0 uses canonical coordinates and exploits the symplectic condition to increase the speed of computation. COSY 5.0 contains a library for the computation of matrix elements of all commonly used corpuscular optical elements such as electric and magnetic multipoles and sector fields . The corresponding formulas were generated algebraically by the computer code HAMILTON . Care was taken that the optimization of optical elements is achieved with minimal numerical effort. Finally COSY 5.0 has a very general mnemoniç input code resembling a higher programming language.

متن کاملFirst observation of 140-cm drift ionizing tracks in the ICARUS liquid-argon TPC
This is a short note to acknowledge the successful operation of a 140-cm drift liquid argon TPC built in the framework of the ICARUS experiment. We show few cosmic muon tracks crossing the whole drift volume from the wire planes to the cathode. Data were taken at drift "elds of 450 and 500 V/cm. ( 2000 Elsevier Science B.V.

We discuss how to use the large-gain bandwidth of an X-ray SASE-FEL to produce femtosecond long pulses by chirping and compressing the output FEL radiation. We consider the power level, spectral width, and intensity #uctuations of the compressed X-ray pulses, compared to the case with no compression. ( 2000 Elsevier Science B.V. All rights reserved.

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...
متن کاملUncountable groups have many nonconjugate subgroups
We prove that any uncountable group G of power ~, has at least 2 subgroups not conjugate in pairs. The paper is very self-contained, assuming no knowledge except cardinal arithmetic (and the definition of an (abelian) group).
