Abstract 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 (320 mm in diameter). iron dominated magnets superconducting coils have been widely used similar facilities such as A1900, BigRIPS, Super!FRS RISP advantages low request for installation precision, simple fabrication cost, but they cold mass helium containment, which result long time cooling down pressure rise...
A prototype laser ion source that could demonstrate the possibility of producing intense pulsed high charge state beams has been established with a commercial Nd:YAG (Emax=3 J, 1064 nm, 8–10 ns) to produce plasma for research Laser Ion Source (LIS). At test bench, purity (99.998%) aluminum and lead targets have tested experiment. An Electrostatic Analyzer (EIA) Electron Multiply Tube (EMT) detector were used analyze energy distribution ions produced by source. The maximum states Al12+ Pb7+...

A compact solenoid for the China Accelerator Driven Subcritical System (China-ADS) injector II has been developed. It includes a focusing and two steering dipoles. The magnet is with an entire length of 160 mm, including helium vessel side flanges. Nonlinear optimization method was used to meet requirement strength stray field minimized volume. dipoles are placed inside reduce size. structural analysis, quench protection design, fabrication test results presented in this paper.
