The recently recommissioned Fermilab muon g-2 experiment is aiming to determine the anomalous magnetic moment of the muon to 140 ppb. To achieve this level of precision, the magnetic field seen by the muon must be know at fraction of a ppm level, which puts limits on the required magnetic field uniformity. This paper provides an overview of the g-2 magnet systems; the inflector magnet, the...
The fragment separator of the HIAF (High Intensity Heavy-ion Accelerator Facility) project called HFRS requires quadrupoles with high gradients( 11.4 T/m) and large bores (gap width of 160 mm). The iron dominated magnets with superconducting coils have been widely used in the similar facilities such as A1900, BigRIPS, Super-FRS and RISP with the advantages of low request for coils...
High charge state ECR ion source has become an indispensable machine in heavy ion associated physics research. It has got remarkable advancement in the last several decades. Modern heavy ion accelerator technology needs very intense highly charged heavy ion beams, therefore very high performance ECR ion sources are needed by many large scale heavy ion facilities. So called 3rd generation ECR...
A superconducting magnet has been developed for SECRAL II ion source at IMP. The design of this magnet is based on SECRAL, with sextupole coils external to the axial solenoids to reduce Lorentz force between sextupole coil’s end and solenoids. The magnet consists of a set of sextupole coils and three solenoids to generate a confinement magnetic field. All the coils use a NbTi conductor and are...
NICA is an accelerator collider complex under construction at the Joint Institute for Nuclear Research in Dubna. The facility is aimed at providing collider experiments with heavy ions up to Gold in the center of mass energy from 4 to 11 GeV/u and an average luminosity up to 1∙10^27 cm-2 s-1 for Au^79+. The collisions of polarized deuterons are also foreseen. The facility includes two injector...
This paper presents a 8T solenoid used to focus and steer the heavy ion beams of the Facility for Rare Isotope driver linac at Michigan State University. It includes a main focusing solenoid, two bucking coils, two pair of horizontal and vertical correctors. The magnet is assembled with an entire length of 516 mm, including the helium vessel, ICR vacuum flanges and also the VCR for the helium...
