Orbit Reconstruction, Correction, Stabilization and Monitoring in the Atf2 Extraction Line
نویسنده
چکیده
The orbit in the ATF2 extraction line has to be accurately controlled to allow orbit and optics corrections to work well downstream. The Final Focus section contains points with large beta function values which amplify incoming beam jitter, and few correctors since the steering is performed using quadrupole movers, and so good orbit stability is required. It is also essential because some magnets are nonlinear and can introduce position-dependent coupling of the motion between the two transverse planes. First experience monitoring the orbit in the extraction line during the ATF2 commissionning is described, along with a simulation of the planned steering algorithm.

Beam-based Alignment, Tuning and Beam Dynamics Studies for the Atf2 Extraction Line and Final Focus System*
Using a new extraction line currently under construction, the ATF2 experiment plans to test the novel compact final focus optics design with local chromaticity correction intended for use in future linear colliders. With a 1.3 GeV design beam of 30nm normalised vertical emittance extracted from the ATF damping ring, the primary goal is to achieve a vertical spot-size at the IP waist of 37nm. We...

Introduction: Correction of Saddle nose deformity is one of the most challenging issues in facial plastic surgery. Materials and Methods: In this study, a single structure in the form of L-strut was attempted to be created by using one 0.035" Kirschner wire and an autologous costal graft out of the 10th and 11th ribs. This study involved 13 cases, most of whom were traumatic. The corrective ...

One of the most preprocessing steps before the classification of hyperspectral images is supervised feature extraction. Because obtaining the training samples is hard and time consuming, the number of available training samples is limited. We propose a supervised feature extraction method in this paper that is efficient in small sample size situation. The proposed method, which is called weight...
متن کاملAdvanced Motion Correction Methods in PET
With the arrival of increasingly higher resolution PET systems, small amounts of motion can cause significant blurring in the images, compared to the intrinsic resolutions of the scanners. In this work, we have reviewed advanced correction methods for the three cases of (i) unwanted patient motion, as well as motions due to (ii) cardiac and (iii) respiratory cycles. For the first type of ...

The authors would like to make the following corrections to the above article. Owing to an author error, the representative images presented in Supplementary Figure 5B (right panel) and Figure 3A (middle left) were from the same file by mistake. The reused image in Supplementary Figure 5B was replaced with the corrected one from the original experiments. Note that the quantified results present...
