High Precision Survey and Alignement of Large Linear Colliders - Vertical Alignment -

چکیده
Abstract. Future linear colliders of 1 TeV energy like TESLA at DESY require new techniques of precise alignment. The planned 33km long accelerator facility will be established in a subterraneous tunnel, which follows an equipotential expanse. The required accuracy for the vertical alignment of the accelerator components is 0.2mm per 600m. To fulfill this demand, a HLS with a free surface ("half filled pipe") has been developed. For scanning the fluid surface ultrasonic measurement equipment is used. A new concept of “in-situ” calibration which eliminates drifts of the sensor as well as temperature effects is presented, supported by results of a HLS-test installation of up to 1 km in length. An accuracy estimation for the adjustment of the accelerator components is made.

High Precision Survey and Alignment of Large Linear Accelerators
Future linear accelerators require new survey techniques to achieve the necessary alignment precision. For TESLA, the demanded accuracy for the alignment of the components is 0.5mm horizontal and 0.2mm vertical, both on each 600m section. Other proposed linear colliders require similar accuracies. These demands can not be fulfilled with common, open-air geodetic methods, mainly because of refra...
متن کاملTHE LINEAR COLLIDER ALIGNMENT AND SURVEY (LiCAS) PROJECT
For the next generation of Linear Colliders (LC) the precision alignment of accelerator components will be critical. The DESY applied geodesy group has developed the concept of an automated ”survey train”. The train runs along the accelerator wall measuring the 3D position of a set of equispaced reference markers. This reference structure is then used to align the accelerator components. The Li...

Frequency Scanning Interferometry (FSI) has been developed for high precision, simultaneous, absolute distance measurements along multiple lines of sight. In the ATLAS semiconductor tracker, FSI will be used to measure lines of sight between nodes of a geodetic grid, attached to the support structure. Movements of the detector modules on the order of ten microns will be monitored by measuring c...

Various approaches may be taken to respond the ever-changing environment in our world. These approaches are usable merely when the alignment in organizations is implemented as a significant and fundamental principle. From the objective point of view, this study is a causal research, since it tries to explain one of the main causes of export performance improvement. From the result standpoint, t...
متن کاملQuadrupole Alignment and Trajectory Correc- Tion for Future Linear Colliders: Slc Tests of a Dispersion-free Steering Algorithm
The feasibility of future linear colliders depends on achieving very tight alignment and steering tolerances. All proposals (NLC, JLC, CLIC, TESLA and S-BAND) currently require a total emittance growth in the main linac of less than 30-100% [1]. This should be compared with a 100% emittance growth in the much smaller SLC linac [2]. Major advances in alignment and beam steering techniques beyond...
