  This work started in the context of NSLS2 project at Brookhaven National Laboratory. The NSLS2 control system foresees a very high number of PV variables and has strict requirements in terms of archiving/retrieving rate: our goal was to store 10K PV/sec and retrieve 4K PV/sec for a group of 4 signals. The HyperArchiver is an EPICS Archiver implementation engined by Hypertable, an open source database whose internal architecture is derived from Google's Big Table. We discuss the performance of HyperArchiver and present the results of some comparative tests.

  EPICS [1] was chosen as general framework to develop the control system of SPES facility under construction at LNL [2]. We report some experience in using some commercial devices based on Debian Linux to control the electrostatic deflectors installed on the beam line at the output of target chamber. We discuss this solution and compare it to other IOC implementations in use in the Target control system.
