Detailed measurements of the wavelength shifting fiber response to a stable and reliable light source are presented. Particulars about materials, a double reference method, and measurement technique are included. The fibers studied were several hundred Kuraray, Y-11, multiclad, 1.2-mm outer diameter wavelength shifting fibers, each cut from a reel to about one meter length. The fibers were polished, mirrored, and the mirrors were UV epoxy protected. Each fiber passed quality control requirements before installation. About 94% of the fibers tested have a response within 1% of the overall mean.

The four magnet types discussed in this report are briefly described in Section 1 of this report. However, for most purposes a discussion of random construction errors needs to deal with only two classes of magnets: collared cosine-theta and superferric. They are discussed in Section 2 and Section 3, respectively. Magnetization effects in the cosine-theta magnets are treated in Section 4. 42 refs., 40 figs., 31 tabs.

A low beta insertion has been installed at the BO straight section of the Tevatron, the location of the Collider Detector Facility. The focus is achieved with four superconducting quadrupole doublets. The engineering design and performance of this system exclusive of beam behavior will be described including the magnets and their power supply, quench protection and cryogenic subsystems.

Employing a neutral kaon beam at the Argonne Zero Gradient Synchrotron, a high-resolution magnetic spectrometer, and a neutron detector, differential cross sections have been obtained in the forward direction [$0.045<|t|<0.18$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$] for the reaction ${K}_{L}^{0}p\ensuremath{\rightarrow}{K}^{+}n$. Previous studies of the time-reversed process in deuterium, ${K}^{+}d\ensuremath{\rightarrow}{K}^{0}p(p)$, have not yielded direct cross-section measurements in the forward direction because there is an inhibition of the non-spin-flip process in deuterium due to the Pauli exclusion principle. Nevertheless, our data are in agreement with the extracted free-neutron cross sections of deuterium studies as determined from the impulse and closure approximations.

The NAL Main Ring extraction system has delivered both slow and fast extracted beam at 100, 200 and 300 GeV. Construction progress, operating conditions, instrumentation and beam characteristics are discussed.

T HERE is nothing more elusive than capital. Economists speak of the flow of capital as if we were dealing with a river which, rising in the mountains, finally finds its way to the ocean, receiving rivulets as it progresses, turning water wheels, bearing on its bosom all kind of craft, fertilizing lands by its overflow or as the result of irrigation projects, and finally by joining the Gulf Stream coursing around the globe. The simile is not a bad one, but we must not overlook the fact that the water is apt to be sucked up by whirlwinds or by trade winds-to be again scattered over the earth at some distant point, while at all times the sun is absorbing moisture from the stream to be poured forth again as rain. Just as it is impossible accurately to measure the fluctuations in the volume of water in
