Abstract In 2018 the high energy X-ray beamlines P07[1] and P21b[2] at DESY’s storage ring PETRA III received new undulators. The two identical devices were built by an industry collaboration of Research Instruments GmbH Kyma S.p.A. according to specifications. They have a magnetic length 4 m, period 21.2 mm deflection parameter K 1.41 gap 7.0 mm. We report about experience during magnet tuning...

2014 This summary reviews the information and new results presented at this Conference and compares the present overall performance of the major electrostatic accelerators to that at the time of the last Conference, four years ago. The advances in electrostatic accelerator technology in the four year period are discussed in terms of accelerator tube improvements, electrostatic charging system i...

introduction: intensity modulated radiation therapy (imrt) is one of the cancer treatment methods. it is important to selectively aim at the target in this way, which can be performed using a multileaf collimator (mlc). materials and methods: in order to specifically irradiate the target volume in radiotherapy to reduce the patient absorbed dose, the use of multileaf collimator has been investi...

introduction electron linear accelerator (linac) can be used for neutron production in boron neutron capture therapy (bnct). bnct is an external radiotherapeutic method for the treatment of some cancers. in this study, varian 2300 c/d linac was simulated as an electron accelerator-based photoneutron source to provide a suitable neutron flux for bnct. materials and methods photoneutron sources w...

A bstract The extension of the Standard Model with two gauge-singlet Majorana fermions can simultaneously explain beyond-the-Standard-model phenomena: neutrino masses and oscillations, as well origin matter-antimatter asymmetry in Universe. parameters such a model are constrained by oscillation data, direct accelerator searches, big bang nucleosynthesis, requirement successful baryogenesis. We ...

A 1MV Tandem Proton Accelerator is being developed for the industrial applications such as high-energy implantation and explosive detection. The proton accelerator consists of a 10mA negative hydrogen ion source, two Einzel lens, accelerating tubes, a gas stripper, a 1MV 30mA Cockroft-Walton high voltage power supply, vacuum pumping system, and a high pressure insulating gas system. The large c...

One of the most vexing questions facing researchers interest in the World Wide Web is how the performance of Web Server could be improved. In this paper we discuss the results of our investigation on potential of httpd accelerator (phhttpd) to improve web server performance. This paper presents comparative results for running the Web server with and without an accelerator, and measures the effe...

The status of PAMELA (Particle Accelerator for MEdical Applications) – an accelerator for proton and light ion therapy using a non-scaling FFAG (ns-FFAG) accelerator – is reviewed and discussed.

This paper describes a hardware accelerator for elliptic curve cryptography. The accelerator performs Galois field operations as a series of microcode instructions operating on 32-bit subsections of operands, which represent elements from GF(2) in a binary polynomial basis. The accelerator may be used for arbitrary size elliptic curves up to a field degree of 512. Parallelism between operations...
