ailliam A. henzel: General Purpose Bending Magnet
It will be desirable to have a general purpose bending magnet available for use
with the Bevatron The design discussed below, while tentative, is believed to
incorporate most of the desired properties for use with the external beam. Sugges-
tions for improvements, modifications. etc. should be addressed to Dr. W.A. lienzel
The primary power supply for use with the magnet is capable of delivering 360KW
continuous or 540KW pulsed at about 15 percent duty. It should be possible to
operate two magnets with the design discussed below on pulsed operation. The rise
time of the pulse magnet, as limited by the generator field rise rate,will be of the
order of 2 sec.
Five-Foot Magnet Specification
agnetic Volume (gap x width x length) 4 x 14" x 60"
.Iaximum Field 18,000 gauss
Power Required 200 - 300 F4
Proton Momentum 6.5 Dev/c 0.6 Bev/c
Enclose Angle 70 870
Proton Radius of Curvature 40' 4'
Deviation of protons from a
straight line thru the end
points of the path 0.94" 121
The magnet described above, when used in the re-entrant section on the inner
radius of the Kest Tangent tank, will permit measurements up to 4.5 Bev/c before
the positive particles will strike the main Bevatron magnet yoke. Higher energy
particles will have to be observed at shorter monitoring distances.
Melvin Ruderman: Experiments Relating to Gyromagnetic Ratios
of Heavy Mesons
An experiment is discussed v:hich may give an estimate of the gyromagnetic
ratio of hyperons. Lven a cualitative knowledge may be useful. If A/t is some
state of n- + p, it will almost certainly have 4/J K0. A neutral 'fundamental
particle- (described by the 'bare' Dirac equation, like an electron) has /J = 0.
A summary of relevant data on nf + p--) A0 + K is given in table I.
These data seem to imply:
(1) Af\0 is produced backwards in c.m. and therefore comes out rather
- slowly in the laboratory. (A strong backward peaking indicates large
Here’s what’s next.
