Experience with Superconducting Cavity Operation in the Tesla Test Facility
A description of the TESLA Test Facility, which has been set up at DESY by the TESLA Collaboration, will be given. Measurements of the superconducting 9-cell cavities in vertical and horizontal test cryostats will be presented, as well as the experience with the first two accelerator modules in the TTF linac. Future cavity R&D efforts will be described.
متن کاملElectromagnetic perspective on the operation of RF coils at 1.5-11.7 Tesla.
In this work experimental and numerical studies of the MR signal were performed at frequencies ranging from 64 MHz to 485 MHz, utilizing three different MRI coils: a single-strut transverse electromagnetic (TEM)-based coil, a TEM resonator, and a high-pass birdcage coil. The experimental analyses were conducted using 1.5 and 8 Tesla whole-body systems and volume RF head coils. The simulation da...
متن کاملTesla Polarimeters
We describe a study of high-energy Compton beam polarimeters for the future ee linear collider machine TESLA. A segment of the beam delivery system has been identified, which is aligned with the ee collision axis and which has a suitable configuration for high-quality beam polarization measurements. The laser envisaged for the polarimeter is similar to an existing facility at DESY. It delivers ...
متن کاملTESLA FEL 2004-06 July 2004 Expected properties of the radiation from VUV-FEL at DESY (femtosecond mode of operation)
For the next three years the nominal ”long pulse” (200 fs) mode of FEL operation at VUVFEL, based on a linearized bunch compression, is not available due to the lack of a key element – a 3rd harmonic RF cavity. Essentially nonlinear compression leads naturally to a formation of a short high-current leading peak (spike) in the density distribution that produces FEL radiation. Such a mode of oper...
متن کاملSolid State Tesla Coil
Some years ago I developed an interest in Tesla coils. I was teaching a senior elective course at Kansas State University where we talked about power MOSFETs and topics related to high voltages and currents. I decided to use a Tesla coil as a class project. We would talk about design aspects, then design, build, and test a coil. The best description of the results of that plan was fiasco, or ma...
