When the luminosity of the LHC at CERN is upgraded, the final focusing quadrupole magnets will receive a much higher energy deposition in their coil windings. To better understand the thermal behavior of coil windings at temperatures below -and some kelvin above- the helium lambda transition point, several numerical models have been developed. These models have been partially validated with...

Axions are amongst the most promising dark matter candidates in modern cosmology. IAXO, the International AXion Observatory, once established, will operate the most ambitious solar axions detector to date. The sensitivity of the IAXO detector to the axion-photon coupling is one order of magnitude beyond the limits of the current detector, the CERN Axion Solar Telescope (CAST).
Although...

The European Spallation Source is a 5 MW, 2.0 GeV long pulse proton machine, currently under construction in Lund, Sweden. Its superconducting linear accelerator will use three types of cavities, i.e. double-spoke resonator cavities, medium-β and high-β elliptical cavities. The superconducting section of the ESS linac will be composed of 13 spoke cryomodules (each with 2 spoke cavities), 9...

The R3B-Glad superconducting Magnet is a large acceptance dipole dedicated to the analysis of Reactions with Relativistic Radioactive ions Beams on the future FAIR facility at GSI Darmstadt. The original shape of the cryogenic tank and fluid distribution was imposed by the compact design of the six tilted and trapezoidal racetrack coils. The coils, electrically connected in series in a...

The challenge of cooldown the huge cold mass up to 1400 tons (dominated by iron) to 4.5 K is addressed as one of the most important features for Super-FRS cryogenics at FAIR. For such large cold mass the precooling with LN2 is necessary due to the reason that approximately ~80% of the cool down load is from 300K to 80K. The capacity of the LN2 precooler at 80 K as well as the 4.5 K cooling...

Transition-edge sensors are widely recognized as one of the most sensitive tools for the photon and particles detection in many areas – from astrophysics to quantum computing. Their application became practical after understanding that rather than being biased in a constant current mode, they should be biased in a constant voltage mode. Despite the methods of voltage biasing of these sensors...

The carbon ion cancer therapy is widely spreading because of its high curative effects and low burdens on patients. The carbon ions are delivered to patients through some electromagnets on the rotating gantry. A rotating gantry is an attractive irradiation equipment, because the carbon ions can be irradiated to a tumor from any direction without changing the posture of the patient. On the...

The Advanced Rare IsotopE Laboratory (ARIEL) is a major expansion of the Isotope Separation and Acceleration (ISAC) facility at TRIUMF. The key part of the ARIEL project is a superconducting radiofrequency (SRF) electron linear accelerator (E linac). E-linac helium cryogenic system was designed to meet the ARIEL specifications. The HELIAL LL helium liquefier by Air Liquide Advanced...

The mathematical model based upon the authors’ previously introduced unclosed shield physical conception was developed. This model allows calculation of the magnetic field radial and longitudinal components in shield systems. One-dimensional problem of a thin-wall coil with the unclosed shield for the various relative positions of the shield and the solenoid was solved. Evaluation of magnetic...

The detection of a second sound wave, excited by a quench, has become a valuable tool in diagnosing hot spots and performance limitations of superconducting cavity. Several years ago, Cornell developed a convenient detectors (OSTs) for these waves that nowadays are used world-wide. In a usual set-up, many OSTs surround the cavity and the quench location is determined by triangulation of the...

After 18 years operation in KEK Tsukuba, the SKS (Superconducting Kaon Spectrometer) magnet was modified and moved to the K1.8 beamline of the J-PARC Hadron Hall in 2009. The SKS magnet has a structure cooled by pool boiling method. During this relocation, the cooling scheme of the SKS magnet was changed to use three GM-JT cryocoolers from the previous 300-W helium refrigerator. Since this...

In the framework of the LHC luminosity upgrade, the development of high field superconducting magnets is under way. The resulting peak field of about 12 T requires the use Nb3Sn as superconductor. Due to the high stored energy density and the low stabilizer fraction, quench protection becomes a challenging problem. Accurate simulation of quench transients in these magnets is crucial to the...
