TITLEj Investigation of the magnetic field configuration in the X-blocks of the proton synqhrotron PERIODICAL: Pribory i tekhnika eksperimenta, no.4, 1962, 212-217 TEXT: The magnetic field configuration is measured in 14 compensating blocks at various levels of induction from 8o gauss Lip to 8000 gauss. Magnetic field gradients are measured with an accuracy of better than 0.1% and the displacement of the neutral point obtained with an accuracy of 0.05 to 0.07 mm.. A plexiglass carriage is located on the magnet p~oles and can traverse the whole length of the block (1910 mm). This carriage contains three pairs of permal 'loy probes for measurements in low fields and three pairs of coils for the medium and large fields. The field characteristics are measured at 31 points along the 14 X-blocks. The distribution of the field and its gradient is obtaine'd near the axis of symmetry for 5 values of induction (82,.lo6, 210, 2600 and 7500 Oe) and on 6 of the C-blocks at Card 1/2 S/120/62/000/004/040/o47 Investigation of the magnetic E039/E420 84oo oe. These measurements are compared with similar measurements on C-blocks. It is shown that displacement of the neutral point depends on the residual field. Displacement also occurs in strong fields because of core saturation. The results are presented graphically and discussed in some detail. The coordinates of the pole pieces with respect to the geodetic markers are determined to an accuracy of 0.03 to 0.04 mm. There are 8 figures.

TITLE: 11-Mesic Molecular Processes Hydrogen PERIODICAL: - Zhurnal eksperimentallnoy I teoreticheskoy I'Izlki, 1959, Vol 37, Nr 6, pp 1652-1662 (USSR) ABSTRACT: A theoretical analysis was made of the mesic atomic and mesic molecular processes in a medium of hydrogen isotopes (the formation of mesic moleculvs, HM + H (2) ----> (HO) H(2)) elas'.tc collisions arid-charge exchange of mesic at-onis,H 1) + H(2) ~L H(l) (2) (1) (2) G) + ~(2) Iti + H , H ~i + H' H /i ). The calculations were performed on the BESM Card 1/4 machine with compensation for the motion of the nuclei. ~L Mesic Molecular Processes in Hydrogen 76981 The magnitude of the correction was of the order of r1l /M. The mesomolecular processes of 4 -mesons whh hydrogen are due to the neutrality of mesic atoms. This is owing to the fact that at distances greater than Bohr's orbits of mesoatoms (2.57 X 10_11~ cm), the nuclear charge Is practically fully shielded by tne charge of the meson. Such a condition resuits in a peculiar catalysis of reactiorc in hydrogen (or, its isotope mixtures), which was predlcted by A. D. Sakharov (Report Phys. Inst. Acad. Sciences USSR, Moscow, 1948), and was experimentaliy investigated b"; A. Ashmore, R. Nordhagen, K. Strauch, and B. M. Townes (Proc. Phys. Soc., 71, 16l, 1958).

The in- fluenoe of clusters on the bunching of particles can be neglected. A de- crease of df,(z)/dz and an increase of ~ max and dEO(z)/dz decrease the influence of Coulomb interactJon.

The solution of the problem by the present me ___-I approaches the true solution with in- creasing K,I~P, and initial density n.i at the point of observation, and with decreasing dV. For a synchrocyclotron, the number of equations of motion of the j-th point of observation is reduced considerably. A pro- visional calculation of these equations of motion with the high-speed electron computer of the AS USSR under conditions similar to those prevailing in the synchrocyclotron of the Obl'yedinennyy inaiitut yadernykh issledovaniy (Joint Institute of Nuclear Research) has shown that the charge maximum of -- 5* jo-5a can be maintained without any loss. For Lz - 2-S z, n(O,z) .n2; K - 11, z(t) can be calculated with an accuracy of 5~6. The "mean density" and "increased charge" methods require about the same amount of work. With-_~ z(t) - const, zmin - conat, and zmax - conBt, and if the z-oscillations are ignored, the radial phase oscillations (with respect to r G) cause a phase perturbation" already described by S. Lo-anev (DAN, 1419 no, 5, ~1961)). The automatic phase.control limits the Card 2/3 Mean density method for ... --/020/62/143/006/008/024 B125/B112 amperage. The "mean density" method differs from the "increased charge" method in that the shape of the beam is less changed at the moment of phase porturbation. Booaune of the limited possibilities of the computer the results of the brio inethodB woro not fully oonaintent. The entire nyotom of equations of motion and initial conditions could only be solved for P-4, I - 3, and K - 4, owing to the limited memory of the machine. V. P. Dmi- triyevskiy and G. A.
