STATUS

• ALL THE MODULES ARE IN SCR (EXEPT THE ADCs)
• NEED TO TALK ABOUT THE D0 CLOCK
• NEED TO CALCULATE THE DELAYS (CARLOS)
• NEED TO MOUNT THE CIRCUIT AND SYNCHRONIZE THE
  SIGNALS (WILL TOOK ONE WEEK OF WORK TO BE READY)
• NEED TO BUY AND INSTALL A HD

DAQ

• For this run we have connected 6 PMTs cables
• P1I P2I
• D1I D2I
• P1U P2U
• USING THE DIPOLES TO TRACK THE PARTICLES AFTER
  HIT IN THE P SIDE (NO PMTs INSTALLED IN A
  CASTLES YET), WE WILL HAVE THE FOLLOWING
  EQUATIONS FOR HALO TRIGGERS
• EPI.DI (EP1IEP2I).D1.D2
• EDI.PI (ED1ED2).P1I.P2I

3

• EPU.DI (EP1UEP2U).D1.D2
• EDI.PU (ED1ED2).P1U.P2U
• Where E means Early and is due to an halo track
• The elastic triggers will be given by
• PU. DI P1U.P2U.D1.D2
• PI.DI P1I. P2I.D1.D2
• Not requiring that the in time hits be
  diagonally opposite
• The schematics is almost the same as in the
  engineering run shown in the figure.
