A laboratory study has shown that the first-half of self-shearing 2-in-1 self-threading pins, sizes 0.031 inch and 0.024 inch, fail to reach full channel depth when placed with either a hand wrench or an Auto Klutch handpiece. The average discrepancy of penetration is about 0.75 mm. This discrepancy in seating results in a significant excess pin length(More)
The Accelerator Description eXchange Format (ADXF) is in response to the Iselin-Keil-Talman letter[1], which calls for a new accelerator description standard aimed to provide connectivity between a variety of beam-dynamics programs and heterogeneous data sources. ADXF represents a flat and complete description of the current accelerator state. It has been(More)
Chromaticity compensation Q 0 x Q 0 y 0 is required to avoid the head-tail" eeect in all high-energy accelerators. A potential advantage of the MM obius" scheme, or any other strongly coupled lattice, is that, because of cooperation between damping in the two planes, a less-restrictive condition, Q 0 x , Q 0 y , should besatisfactory. This chromaticity(More)
Being an integral part of accelerator software, accelerator description aims to provide an external representation of an accelerator’s internal model and associative effects. As a result, the choice of description formats is driven by the scope of accelerator applications and is usually implemented as a tradeoff between various requirements: completeness(More)

The asymmetry in the process y + p +x0 +p with polarized photons has been measured at 6 GeV for momentum transfers from t = -0.4(GeV/c)2 to t = -1.1(GeV/c)2. The experiment was performed at the Stanford Linear Accelerator Center using coherent bremsstrahlung from a diamond crystal. A coincidence was made between the recoil proton in the S.L.A.C. 1.6 GeV/c(More)
Any existing circular accelerator can be converted inexpensively for \Mobius operation" by introducing one \twist" element that interchanges horizontal and vertical betatron oscillations on each particle passage. Two, not one, traversals of the ring are required to return to a corresponding state. The ring exhibits properties di erent from and, in(More)
Although a number of reports have been published demonstrating that carious dentin is less permeable than normal dentin, these reports have been qualitative rather than quantitative. The purpose of this in vitro study was to apply a quantitative technique to the study of the permeability of carious human teeth before and after excavation, before and after(More)
Chromaticity compensation (Q 0 x Q 0 y 0) is required to avoid the \head-tail" eeect in all high-energy accelerators. A potential advantage of the \MM obius" scheme, or any other strongly coupled lattice, is that, because of cooperation between damping in the two planes, a less-restrictive condition, Q 0 x ?Q 0 y , should be satisfactory.
