1. Current run status

HV system

  • in CLAS everything works for now
  • there are good spare boards: 1461N - 9 boards, 1461P - 2 boards
  • there is no good spare Lecroy mainframes; 2 in repair since November 2008, 1 from July 2008, waiting for status; 3 in Counting House, repair needed, RMA under way;

there is one Lecroy mainframe (temporary rack in EC), can be replaced with sy1527 (from Yuri ?) so we'll have 1 spare mainframe and 8 1461N boards, will do it after the run

  • two SY1527LC mainframes with 'full crate' problem (when crate is full, first board shuts off and sometimes disapeares) have to be repaired in CAEN, will send them one by one starting from ECHV2 where TCP/IP is broken as well
  • multi-pin HV connectors must be improved, need to ask manufacturer if glue can be used or some other solution can be recommended; Sergey P. will contact company; connectors must be improved, otherwise it will be a big problem for the CLAS and CLAS12
  • will be good to modify medm gui generating process to have geographic addressing information in gui
