  Beam loss monitor system has been designed in many electron storages in order to indirectly measure lost electrons, which can be used to analysis beam loss mechanism and beam life. It can contribute to beam commissioning and improving stable operation of storage ring. According to lattice structure of the HLS II storage ring, 64 beam loss detectors have been located in the upper, lower, inner, outer side surfaces of vacuum chamber in the HLS II storage ring. Some preliminary researches based on the HLS II BLM system have been done. The results in successfully stable operation and unsuccessfully stable operation in beam commissioning stage were compared. Analysis of a sudden lost beam phenomenon were carried out.

  In this paper we showed a systematic method of appropriate parameter choice for a circular pp collider by using analytical expression of beam-beam tune shift limit started from given design goal and technical limitations. Based on parameters scan, we obtain a set of parameters for SPPC with different circumferences like 54km, 78km or 100km and different energies like 70TeV or 100TeV. We also showed the first version of SPPC lattice although it needs lots of work to do and to be optimized.
