  HIRFL (Heavy Ion Research Facility in Lanzhou) is a heavy ion accelerator complex which consists of two cyclotrons and two cooling storage rings. The two cyclotrons SFC (Sector Focus Cyclotron) and SSC (Seperated Sector Cyclotron) have been operated for more than 20 years. Great efforts have been made to improve the operation efficiency, the facility reliability and increasing beam intensity in the last couple of years. A series of upgrading programs have been accomplished which have resulted in a dramatic enhancement of the HIRFL performance. This paper will review the latest status and development of IMP cyclotrons including SFC, SSC and a compact cyclotron for 7MeV/u 12C5+ beam being built as an injector of an ion therapy synchrotron. Meanwhile, some latest developments of highly charged ECR ion sources installed at the SFC axial beam line will be also presented.

  The HIRFL-CSR facility come into operation by the end of 2007. During operation in recent years, CSR supplied beam for experiments at several terminals and inside both CSRm and CSRe rings. The experiments covers high resolution mass measurement, cancer therapy research, neutron wall, atomic physics using electron target and internal gas target, using injection beam mainly from the SFC of cyclotron injector. New methods and further developments are required to improve the performance of CSR system including multi-gradients measurement method for beam spot commissioning and beam transfer, nonlinear effect correction and stabilization of isochronous mode of CSRe. For suppling of heverier ion beam with proper ernergy, the cyclotron complex should be enhanced and new injector is proposed to replace SFC as injector of SSC.

  The transmission efficiency of HIFIL-SSC had been studied. We found the main reasons of the lower transmission efficiency, and some advices was put forward to improve the transmission efficiency.
