"HOW LITTLE SCIENCE BECAME BIG SCIENCE IN THE USA" by E.L. Goldwasser
.......
By 1960 a number of such specialized experts in the various techniques were
required by a given experiment. So a whole new sociology of research developed.
Scientific papers which used to be signed by one or two people frequently carried
the names of dozens of authors. Today, 100 or even 200 authors loom as a common
occurrence. No one believes any longer that each such author has a fundamental
responsibility for the whole experiment, Names are included in authorship as a
means of providing recognition and reward to all people who contribute in an
important way to an experiment.
....
....... It is true that the new, mammoth detectors that are being
planned and built for the sharply limited number of intersecting beam regions
have a complexity which requires more participating scientists than ever before.
Yet that number should be established by need and not by sociology or the physics
will suffer. ....

The status of the search for low mass WIMPs: 2013
Using information from a recent dark matter symposium at
Marina del Rey and from various publications in 2012 and 2013,
we discuss the most recent evidence and constraints on low mass
WIMPs. There are now five separate experimental limits on such
WIMPs, including a new paper on the XENON100 225 day
exposure. There are very different experimental methods with
different backgrounds that comprise this limit. We speculate on the
possible sources of the reported low mass WIMP signals and
background. We present recent arguments concerning DAMA that
show the possible DM claims are likely misleading. We discuss the
new CDMS claims for a signal and question the very low
ionization in these events. We also discuss an analysis of XENON
100 data that uses information theory that further excludes the
CDMS results.

strong and weak focusing
...
In accelerator physics strong focusing or alternating-gradient focusing is the principle that the net effect on a particle beam of charged particles passing through alternating field gradients is to make the beam converge. By contrast "Weak focusing" is the principle that nearby circles, described by charged particles moving in a uniform magnetic field, only intersect once per revolution.
Earnshaw's theorem shows that simultaneous focusing in two directions at once is impossible. However, ridged poles of a cyclotron or two or more spaced quadrupole magnets (arranged in quadrature) alternately focus horizontally and vertically.[1][2]
Strong focusing was first conceived by Nicholas Christofilos in 1949 but not published (Christofilos opted instead to patent his idea),[3] In 1952, the strong focusing principle was independently developed by Ernest Courant, Milton S. Livingston, Hartland Snyder and J. Blewett at Brookhaven National Laboratory,[4] [5] who later acknowledged the priority of Christofilos' idea.[6] The advantages of strong focusing were then quickly realised, and deployed on the Alternating Gradient Synchrotron. ...
