Signal processing electronics for the beam position monitors (BPM) of the SPring-8 Storage Ring were renewed during the summer shutdown period of 2006. The configurations of the electronics of before and after the alteration are described. The evaluation of the performance of the electronics is shown with the data taken by using the actual beams.

Using channeling phenomena of a crystal is one of the useful ways to handle high energy beams efficiently. We have performed an experiment with a 150–MeV electron beam at Hiroshima University and one with a 12–GeV proton beam at KEK–PS. In this article, these experiments are presented. In addition, examples of applications of bent crystals, such as a possibility of beam collimation at the ILC and a beam separation device at J–PARC, are briefly introduced.

Alignment of accelerators, especially about magnet alignment, is overviewed. Firstly the traditional alignment techniques are reviewed. Then modern techniques in accelerator alignment such as laser trackers, total stations, hydraulic leveling systems, stretched wire systems and beam based alignment are reviewed.

Since the constructed of 12 GeV proton synchrotron started 35 years ago, technologies have been dramatically developed. Computers, software, hydrostatic bearing and scanning tunneling microscope have given us a big impact on accelerator development. Computer aided numerical control machine can realized any shape with an accuracy of nanometer order. Hydrostatic bearing can be used for ultra high-precision tuning and milling, and scanning microscope for the observation of surface roughness with atomic level. In this article, we describe the development of accelerator related precision engineering technologies utilizing these new technologies.

This paper will give an overview of the Australian Synchrotron Project (ASP) storage ring¹⁾. The ASP storage ring is a 3 GeV machine with 14 identical cells and a circumference of 216 m. The injection system is commissioned and the storage ring is currently being commissioned. The facility is expected to be in operation by March 2007²⁾.

Present situation of discussion among PAC, EPAC and APAC to make PAC, EPAC, and APAC to be held every third year to have only one of them be held in a year, and rotate the venue of these Particle Accelerator Conferences among three regions is presented. At present PAC and EPAC are held every second year: PAC in odd year and EPAC in even year. Three APACs that have ever been held were obliged to compete with either PAC or EPAC. Since EPAC has already decided to move to three-year cycle, APAC10 will become the only Particle Accelerator Conference in the year 2010. Being freed from competition with other PACs, APAC10 to be held in Kyoto in May 2010 will be the first APAC that is equivalent to PAC and EPAC in its size and scope.

International Linear Collider Workshop 2006, Joint Meeting ECFA and GDE was held in Valencia, Spain from 6 to 10 November 2006. In this 5 days meeting, many system optimizations, which had been discussed since the last WS at Vancouver, were reviewed. Many interactions among accelerator physicists, high-energy physicists, and theorists would reveal the final design of ILC to us.
