SLAC Pub 7060Some Alignment Considerations for the Next Linear ColliderRobert E. Ruland, Stanford Linear Accelerator Center, Stanford, CA 943091.0 INTRODUCTIONNext Linear Collider type accelerators require a new level of alignment quality. The relative alignment of these machines is to be maintained in an error envelope dimensioned in micrometers and for certain parts in nanometers. In the nanometer domain our terra firma cannot be considered monolithic but compares closer to jelly. Since conventional optical alignment methods cannot deal with the dynamics and cannot approach the level of accuracy, special alignment and monitoring techniques must be pursued.2.0 COMPONENT PLACEMENT TOLERANCESComponent placement tolerance specifications define the alignment operation. The definition of these tolerances has changed over recent years, resulting in significantly looser specifications. At the same time, the alignment requirements of NLC type machines are intrinsically more demanding, effectively offsetting these reductions.The available space here does not allow a detailed discussion of all parts of an NLC design. While the following discussion will focus on the main linac damping ring alignment, most of it is nonetheless directly applicable to the other machine parts.2.1 DefinitionsOriginally, alignment tolerances were calculated as the offset of a single component resulting in an intolerable loss of luminosity. This seemed a reasonable way to proceed and immediately gave relative sensitivities of component placement. However, this method had two flaws: it failed to take into account that, firstly, not just one but all elements are out of alignment simultaneously, and secondly, that sophisticated orbit and tune correction systems are applied to recover the lost luminosity. Permissible alignment errors, random or systematic, under these more realistic assumptions are much harder to estimate because they require an understanding of allconceivable interactive effects that go into a simulation and a detailed scenario of tuning and correcting. The continued increase in available computing power has made it possible to calculate the simultaneous offsets of all components. Operating experience from the present generation of colliders has yielded significant advances in orbit tuning and correcting. On this basis, alignment tolerances can be defined as the value of placement errors which, if exceeded, make the machine uncorrectable. Experience with higher order optical systems has shown that alignment tolerances derived in this manner tend to be about an order of magnitude looser than before.’2.2 NLC Linac TolerancesAlignment tolerances according to the first and the most recent definitions have been computed2 and are plotted in Fig. 1. The first curve shows the placement tolerances required to keep dispersion losses under a tolerable 3%, i.e. the machine would operate to design specifications. The placement requirements for adjacent components are a very tight 32.3. Measurement Quality EstimateTo estimate what alignment accuracy could be achieved in a conventional alignment procedure for the main linac, the process has been simulated. Fig. 4 shows the resulting tolerance curve. Comparing Fig. 1 to Fig. 2, one can see, that conventional alignment can support the ab initio alignment requirements but not the running tolerance requirements.Fig. 2. Quadrupole alignment tolerances vs. alignment accuracy3.0 DATUM DEFINITIONSince the earth is spherical, a slicethrough an equipotential surface, i.e. asurface where water is at rest, shows anellipse. For a project the size of an NLC,this has significant consequences.Fig. 3. Effect of earth curvature on linear and circularaccelerators3.1 Tangential Plane or Equipotential SurfaceTraditionally, accelerators were built in atangential plane, sometimes slightly tilted toaccommodate geological formations. All pointsaround an untilted circular machine lie at the sameFig. 4. Three plane lay-outheight (Fig. 3), but a linear machine such as theNLC cuts right through the equipotential iso-lines. The center of a 30 km linear accelerator is 17 m below the end points. To alleviate the problems one could build the accelerator on more than one plane, e.g. building the linacs and the final focus/detector section on three separate planes reduces the sagitta to 1.9 m (Fig. 4). To avoid the “height” difference completely, one would need to build the machine along an equipotential surface.3.2 Lay-out DiscussionSince most surveying instruments work relative to gravity, the “natural” solution is a lay-out which follows the surface generated by equal gravity, the equipotential surface, although, for conventional alignment methods, the choice of a tangential surface adds just one additional correction. The choice of lay-out surface does have a major impact upon which special alignment methods can be used: a diffraction optics Fresnel plate alignment system requires a straight line of sight, but a hydrostatic level system can not accommodate height differences of more than a few centimeters.4.0 SPECIAL ALIGNMENT SYSTEMSThe conventional alignment accuracy can be improved by adding alignment systems to the measurement plan which are optimized for the measurement of the critical dimension. The key element of any of these alignment schemes is to generate a straight line reference. Fig. 5 gives an overview of straight line reference systems categorized by their working principle.3 Most of these systems can also be used to establish on-line monitoring systems.4.1 Mechanical Reference LineA stretched wire is used to represent a straight line. While in the horizontal plane a wire projects to a first order a straight line, in the vertical plane it follows a hyperbolic shape due toFig. 5. Straight line reference systemsgravitational forces. The deviation from a straight line in the vertical is a function of the wire’s weight per unit length, wire length and tension. A 45 m spring steel wire with 0.5 mm diameter under a maximum tension has a sagitta of about 6 mm. A comparable wire made of a silicon-carbide material4 which has the same tensile strength but at only one tenth of the spring steel’s weight per unit length, creates a sagitta of only 0.6 mm. For very accurate measurements, deviations of a wire from a straight line in the horizontal plane must also be considered. These deviations are created by internal bending moments caused by molecular stress of the material. The bending moments can be reduced to negligible size by heat-treating the wire or by stretching it into the yield range.4. 1. 1. Optical Detection The “Light Shadow Technique”(Fig. 6) is implemented with a variety of detectors and canprovide very cost effective solutions, excellent range andresolution. At LLNL, a GaAs infrared emitting diode Fig. 6. Light shadow technique illuminating a silicon phototransistor across a 2.5 mm gap combination was used to measure the deflection of a wire in an electro-magnetic field.5 This set up was part of a system to align the solenoid focus magnets on the ETA-II linear induction accelerator. To stabilize drift problems, the phototransistor was replaced with CdS photoconductors.6 The resolution proved better than 14.1.2. Electrical Detection Electrical pick-ups useinductive or capacitive techniques to measure thewire position. A very simple inductive system wasdeveloped at KEK to support the alignment of theATF linac. The reference wire carries a 60 kHzsignal which is picked up by two coils on either sideof the wire (Fig. 8).8 The differential signal is ameasure for the relative wire position. The accuracyover the measurement range of 5 mm is better than± 30ESRF and CERN, in collaboration with the French company Fogale Nanotech, have developed capacitive sensors. The CERN sensor is bi-axial and resolves the wire position over a range of 2.5 mm to ± 1alignment of components to about ± 50In its simplest form, a laser beam images a spot on a PSD, QD or CCD array, allowing a direct position read-out to fewSLAC Linac/FFTB AlignmentSystem.12,13 The reference line of aFresnel system is defined by the pinhole and the center of the detectorplane (Fig. 12). The Fresnel zone Fig. 12. Fresnel alignment systemplate (Fig. 13) focuses the diffuse light onto the detector, forming an interference pattern (Fig. 14). The design parameters of the zone plates, size, width of strips, and gaps, are a function of the wavelength of the light source, image and object distances, and resolution. Only one Fresnel lens can be in the light path at any time. To incorporate more monitor stations into the system, the zone plates must be mounted on hinges so that actuators can flip the plates in and out of the light path. Since refraction would distort the fringe images to noise, the light path must be in a vacuum vessel.T h e F F T B a l i g n m e n tsystem’s Fresnel zoneplates, which, as anextension to the linacalignment system, are about3.2 - 3.4 km from the detec-tor, can resolve the motionof a zone plate to 5155.0 ERROR PROPAGATIONS WITH ADDITIONAL SYSTEMS5.1. Stretched WireFor the purpose of estimating the error propagation of a wire system over the length of a possible NLC linac the lay-out as sketched in Fig. 16 was assumed. A double overlapping wire arrangement is necessary since it was found that in order to preserve a position survey accuracy of ± 5VI/460The improved wire curve assumes that it will be possible to achieve the present FFTB wire accuracy for a 100 m long wire. This system would be able to fully support the alignment needs.Fig. 17. Wire alignment accuracies5.2. Hydrostatic Level SystemTo simulate the effect of supporting the alignment with a hydrostatic level system, two cases need to be considered. If the machine would be built on a tangential plane, one hydrostatic level system cannot accommodate the height difference. Therefore, the simulation assumes individual 500 m long sections set up like a stair. The second case assumes an equipotential surface as reference plane allowing one continues system. Fig. 18 shows the simulation results.Fig. 18. Hydrostatic alignment accuraciesVI/4616.0 SUMMARYAlthough the NLC requires alignment tolerances an order of magnitude tighter than required for existing machines, results from a conventional alignment will be sufficient to make the NLC correctable. It was shown also that more sophisticated alignment systems can very likely accommodate the operational requirements. While the beam itself is the ultimate judge of alignment, beam based alignment requires costly beam time. To maximize luminosity, the investment in more sophisticated alignment tools may well pay off.1Fischer, G., Alignment and Vibration Issues in TeV Linear Collider Design, Proc.
