Abstract

The mechanical properties of dipole magnets for the superconducting super collider have been characterized. The cold-tests, which were conducted at the Brookhaven National Laboratory and Fermi National Accelerator Laboratory, employed strain-gauge transducers for measuring the coil pressure and end force while the magnet is undergoing cooldown and energization. A discussion on the results is presented.

Abstract

Cold-tests were made on 18 dipole magnet models at the Brookhaven National Laboratory and Fermi National Accelerator Labortory. The 15-m long magnets, which were developed for the superconducting super collider, were evaluated in terms of persistent magnetization currents, eddy currents and magnetization in its iron yoke and cryostat. The results were used to determine the effect of the magnet current on the harmonic field coefficients.

Abstract

Measurements of ac losses have been carried out at the Fermi National Accelerator Laboratory on six prototype and 18 full-size dipole magnets of the superconducting super collider. The tests employed a microcomputer-based measurement system. It quantified the energy dissipation caused by eddy currents and iron core and superconductor magnetization as a function of ramp rate per operating cycle.

Abstract

The quenching behavior of 18 model magnets for the superconducting super collider device were measured. The experiment, which was conducted at the Brookhaven National Laboratory and the Fermi National Accelerator Laboratory, also quantified the reaction to current ramp rate variations in the 15-m long dipole magnets. It demonstrated a drop in the magnet's quench current which is dependent on its ramp rate. This is attributed to eddy currents in the superconducting cable.

Abstract

Variations in the magnetic field angles of dipole magnets for the superconducting super collider have been observed at the Fermi National Accelerator Laboratory. The changes were seen after measurements were made prior to and after the magnet's installation in the cryostat and before and after cold-tests. The field angle shifts due to cold tests were explained by fluctuations in yoke magnetization.

Abstract

Physical review accelerators and beams 3(9), 092001 (2000). doi:10.1103/PhysRevSTAB.3.092001, The conceptional design of the proposed linear electron-positron collider TESLA is based on 9-cell 1.3 GHz superconducting niobium cavities with an accelerating gradient of Eacc >= 25 MV/m at a quality factor Q0 > 5E+9. The design goal for the cavities of the TESLA Test Facility (TTF) linac was set to the more moderate value of Eacc >= 15 MV/m. In a first series of 27 industrially produced TTF cavities the average gradient at Q0 = 5E+9 was measured to be 20.1 +- 6.2 MV/m, excluding a few cavities suffering from serious fabrication or material defects. In the second production of 24 TTF cavities additional quality control measures were introduced, in particular an eddy-current scan to eliminate niobium sheets with foreign material inclusions and stringent prescriptions for carrying out the electron-beam welds. The average gradient of these cavities at Q0 = 5E+9 amounts to 25.0 +- 3.2 MV/m with the exception of one cavity suffering from a weld defect. Hence only a moderate improvement in production and preparation techniques will be needed to meet the ambitious TESLA goal with an adequate safety margin. In this paper we present a detailed description of the design, fabrication and preparation of the TESLA Test Facility cavities and their associated components and report on cavity performance in test cryostats and with electron beam in the TTF linac. The ongoing R&D towards higher gradients is briefly addressed., Published by American Physical Society, College Park, MD
