TITLEj Investigation of the magnetic field configuration in
the Xblocks of the proton synqhrotron
PERIODICAL: Pribory i tekhnika eksperimenta, no.4, 1962, 212217
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 Xblocks. 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 Cblocks at

84oo oe. These measurements are compared with similar
measurements on Cblocks. 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: 11Mesic Molecular Processes Hydrogen
PERIODICAL:  Zhurnal eksperimentallnoy I teoreticheskoy I'Izlki,
1959, Vol 37, Nr 6, pp 16521662 (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
aridcharge exchange of mesic atonis,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 effective croo,.
section of the charge exchange (oh.e.) 'is de,,ermlned

papers on particle trapping for acceleration conditions in

this problem which takes into account the coliective interaction
of particles in the beam and the indu.tlvs properties of that
beam at the moments of onset and break ' A number of experimental
investigations deals with measurements at shf and with electron

equations was solved with the computer 6XM I (BESM I) of the AS USSR for
some typical cases. It was found that a sufficiently large number of re
solutions (N) has to be chosen to be able to neglect the influence of
space charges at small amperage (0.1 a and less) and in order that at
high amperage the influence of Coulomb interaction on the bunching of
particles and the initial conditions for particle acceleration. 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. This work was conducted at the
Vychislitellnjy tsentr AN SSSR (Computation Center of the AS USSR) e.nd

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 jth point of observation is reduced considerably. A pro
visional calculation of these equations of motion with the
highspeed electron computer of the AS USSR under conditions similar to
those prevailing in the synchrocyclotron of the Obl'yedinennyy inaiitut

the charge maximum of  5* jo5a can be maintained without any loss. For
Lz  2S 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,

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

Onthe other hAndj saine interest attaches to the use of radial field compoennts
for the production 6f hard focusing. However, unless there is a longitudinal
field, it is impossible to choose a canbination of radial field and length of
gap,between poles such as to accomu)date all particles with different initial
conditions. An increase in the gap between magnet poles gives rise to oscil
lations that cannot be suppressed by suitable choice of field canponents, and
an increase in the field intensities does not improve the hardfocusing con
ditionsappreciablysince the amplitude of the oscillitions increases with
the linear distance. There are 14 figures,.
