A WIDE - ANGLE MAGNETIC LENS FOR COLLECTING LOW - ENERGY n - M E S O N S IN A SOLID ANGLE OF 10 sr
نویسنده
چکیده
Optical characteristics and construction of a focusing device for collecting low-energy n-mesons in a solid angle of about 4nsr are considered. The focusing device is an axially-symmetric magnetic lens with magnetic field of ~ 100 kOe and pulsating current of ~ 1.4 MA. Parameters of a supply system operating at several hertz rate are given. At area of 100 cm 2 in the focus plane of the system the 30 MeV n -meson flux, produced by 1 GeV electron beam, is ~10-5/e lec t ron with a maximum density of 3x 10 -7 n / c m 2.

Background and Objective: Arthrosis of the hip joint is one of the most common complications of patients and many efforts have been made to find its etiology. One of the subjects important for researchers is morphologic parameters of the hip joint and its relationship with osteoarthritis of this joint. Since these parameters themselves are affected by physical parameters of the body and the rac...
متن کاملA study of magnetic drift motion of particles around the equatorial plasmapause by using the cluster observation
On August 7, 2003 the Cluster spacecraft moved through the dayside magnetosphere. The energetic particle spectrometer on board Cluster provided measurements of an extensive range of energy. Besides, satellite measurements of geomagnetic field showed a gradient magnetic field. It is known that an inhomogeneity of the magnetic field leads to a drift of charged particles. In this paper, the drift ...

The gap anisotropy in Bi 2 Sr 2 CaCu 2 O 8+δ is revisited in the framework of a d-wave scenario in view of the recent angle-resolved photoemission experiment. Based on a tight-binding fit to the normal state dispersion, a detail analysis on the effects of the inclusion of the next harmonic in the d-wave has been presented. Significant effect has been observed in the superconducting T c. The den...
متن کاملUltra-Sharpening of Diamond Stylus by 500 eV O+/O2 + Ion Beam Machining without Facet and Ripple Formation
The price of single point diamond tools with a sharp tip is very high due to complex machining process and highly expensive machining equipments. Yet, the performance is not quite satisfactory. In this paper, we have presented a very simple and cost effective machining process for the sharpening and polishing of diamond stylus using low energy reactive ion beam machining (RIBM). In our method, ...
متن کاملImprovement of position measurement for 6R robot using magnetic encoder AS5045
Recording the variation of joint angles as a feedback to the control unit is frequent in articulated arms. In this paper, magnetic sensor AS5045, which is a contactless encoder, is employed to measure joint angles of 6R robot and the performance of that is examined. The sensor has a low volume, two digital outputs and provides a high resolution measurement for users; furthermore its zero positi...
