In this paper we present the design for a low-cost RF cavity capable of accelerating protons from 100 keV to 1MeV. The system is designed to meet the specifications from the proposed Alceli LTDmedical proton therapy linac, to deliver a 1 nA proton beam current with a 1 kHz repetition rate. We present a design of an RF normal conducting (NC) re-entrant Cu cavity operating at 40MHz consisting of ...

Abstract The helium cryoplant and cryo distribution system (CDS) are key elements of the new superconducting Linac Coherent Light Source (LCLS-II) will provide superfluid to accelerator. consists two refrigerators with an equivalent 4.5 K refrigeration capacity 18 kW each. 37 cryomodules LINAC be operated at a temperature 2.0 accelerate 4 GeV electron beam that generate extremely bright X-ray l...

many of the video processing algorithms cannot be implemented in real time on general computers, due to their computational complexity. for an efficient implementation, a custom hardware that can be reconfigured for the algorithm, is used. in this paper a new acceleration hardware based on fpga elements is proposed. this hardware can be adapted with the processing algorithm through fpga design ...

MedAustron is the Austrian center for hadron therapy and non-clinical research. The accelerator design is based on the PIMMS study [1] and features proton beams of up to 800 MeV and carbon ion beams of up to 400 MeV/u. The accelerator is currently being installed and the beam commissioning has started early 2013. The injector comprising three ECR sources, an RFQ and an IH-mode structure has alr...

Nb3Sn is a promising next-generation material for superconducting radiofrequency cavities, with significant potential both large scale and compact accelerator applications. However, so far, cavities have been limited to cw accelerating fields <18 MV/m. In this paper, new results are presented significantly higher fields, as high 24 MV/m in single cell cavities. Results also from the first ever ...

Please share how this access benefits you. Your story matters. A design for a compact x-ray light source (CXLS) with flux and brilliance orders of magnitude beyond existing laboratory scale sources is presented. The source is bas...

Aim: To develop a simple algorithm that accurately constructs and simulates an Alvarez-type linear accelerator given the initial conditions number of parts. Methods: We wrote in Python, programming language with numerous useful math science libraries, ability to use classes objects. The particles were accelerated electric fields (which we assumed be constant within each cavity at any moment) al...

SPES (Study for the Production of Exotic Species) [1] is a L.N.L. project that will produce by the end of this year the design of a facility for Radioactive Ion Beams (RIBs) originated by fission fragments produced by secondary neutrons; it will be characterized by moderate size, performance and cost and will produce also intense neutron beams for activities both in fundamental and applied Nucl...

In seeded High-Gain-Harmonic-Generation free electron lasers or energy recovery linear accelerators the requirements for the bunch-to-bunch timing and energy jitter of the beam are in the femtosecond and per mill regime. This implies the ability to control the cavity radiofrequency (RF) field to an accuracy of 0.02◦ in phase and up to 1·10-4 in amplitude. For the planned BESSY-FEL it is envisag...

The MedAustron accelerator (Wiener Neustadt, Austria) will deliver clinical beams of protons (60 250 MeV) and carbon ions (120 400 MeV/n) to three ion beam therapy irradiation rooms (IR). Clinical beams and proton beams up to 800 MeV will be provided in a fourth IR, dedicated to non-clinical research. A slow-extracted proton beam of maximum clinical energy reached for the first time the IR3 in ...
