Book Description
The Final Focus Test Beam (FFTB) was conceived as a technological stepping stone on the way to the next linear collider. Nowhere is this more evident than with the alignment subsystems. Alignment tolerances for components prior to beam turn are almost an order of magnitude smaller than for previous projects at SLAC. Position monitoring systems which operate independent of the beam are employed to monitor motions of the components locally and globally with unprecedented precision. An overview of the FFTB alignment system is presented herein.

Book Description
This report describes the current state of work in progress with respect to the geometry, alignment requirements, scenarios, and hardware for meeting the tolerances of the Final Focus Test Beam (FFTB) at SLAC. The methods and systems proposed acknowledge that component motion at the micron level, from whatever cause (ground motion, thermal effects, etc.) must be measured on-line and compensated for on relatively short time scales. To provide an integrated alignment/positioning package, some unique designs for reference systems, calibration of effect electric and magnetic centers, and component movers are introduced. 24 refs., 28 figs.

Book Description
Specialists in the technical components of a synchrotron light source are usually well versed in their field and in the associated technical literature. However, with the rapid and continuing growth of synchrotron radiation research, and with new facilities coming online and being authorized for design and construction around the world, there is a need for a reference book that describes the various technical components of a synchrotron light source in a manner that will be useful to those who lack specialized technical background, but who have responsibility for some part of the design, construction, operation or development of such a facility. This would include technicians, engineers and physicists who have technical background in related fields but no specific experience with a synchrotron light source, and also project managers, laboratory directors, and government officials involved with synchrotron light facilities.College level scientific or engineering training or the equivalent experience is assumed and appropriate mathematics is used throughout. However, the basic concepts in each chapter are given in less technical language and a glossary of terms as well as an index will make the book useful for those with less technical training or experience.

Book Description
In order to optimize tunability and backgrounds in linear collider final focus systems, it is necessary to align strong quadrupole and sextupole magnets with beam-based measurements. Algorithms for alignment have been used successfully on the Final Focus Test Beam (FFTB) beamline at SLAC. Quadrupole magnets were aligned using a shunt technique, with resolutions from 50 microns down to 700 nanometers. Sextupole magnets were aligned by moving the magnets transverse to the beam and observing the kick on downstream beam position monitors. This procedure resulted in sextupole misalignment resolutions of 5 to 20 microns. All magnets were then moved into aligned positions via remote-controlled stages capable of sub-micron resolution. Details of the fitting algorithms, results of the measurement, and potential improvements in the system are discussed.

Book Description
Beam-based alignment of quadrupole and sextupole magnets is crucial for the overall performance of linear collider final focus systems, especially for elimination of backgrounds and higher-order aberrations. At the Final Focus Test Beam (FFTB), alignment tolerances required for achieving the desired spot size are 100 microns in the horizontal and 30 microns in the vertical. Using a combination of independent magnet power supplies, hi-h-resolution stripline beam position monitors and precision magnet movers, the FFTB can be aligned to these tolerances in about 8 hours. Description of the algorithm, presentation of alignment results, and possible improvements to the system are discussed.

Book Description
The Final Focus Test Beam is a transport line designed to transmit 50 GeV electron beams of SLC emittance (3 x 10−1° radian-meters) straight through the central arm of the Beam Switchyard (BSY C line) with a final focus point out in the Research Yard but relatively near the end of the switchyard tunnel. The hardware, methods and procedures outlined in this proposal are dedicated to measuring the placement of mechanical objects with respect to certain defined geometric axes. We wish to emphasize that the very difficult problems of locating the effective magnetic axes of focusing elements, the effective electrical center of beam position monitors and even the effective axis of the incident beam relative to mechanical reference surfaces is outside the scope of this work. Further, this proposal is restricted to the act of measurement and does not consider the vital task of on-line mechanical repositioning of elements that will, in likelihood, be called upon during operation of the system. 16 refs., 16 figs., 4 tabs.
