FPGA performs the sampling, data buffering, and data-flow control functions of the board. Internal memory of the FPGA is used to store data which is a collection of rising/falling edge timestamps which occurred on each channel during a spill. Six DBB are daisy-chained together with upstream and downstream links. The first DBB in each group is directly connected to the acquisition system.

18 Summary Outlook Summary EMR Schedule June 2011 Production will resume in February Some mechanical issues needs to be addressed (patch panels, cabling etc.) Design of final electronic boards for 64-ch. PMT is finalized; routing and production is about to start Firmware for the new VME board must be written and communication protocol must be defined 4 new FEB (without buffer board) for cosmic tests will be equipped with MAROC-3 chips R.Asfandiyarov (U.Genève), Status of EMR Project MICE Video Conference, January 20, / 20

19 Outlook Summary EMR Schedule June 2011 May 2011 First 6 DBB+FEB and 1 VME board should be ready. June fully equipped modules delivered to RAL for test run. After tests these will be shipped back to Geneva for further developments and final construction. November modules (48 planes) should be completed and tested. All DBB+FEB and VME boards should be produced and tested. EMR assembled in Geneva. December 2011 Full EMR installed in RAL - physics run.

After tests these will be shipped back to Geneva for further developments and final construction.

20 June 2011 Test run with 3 EMR modules at RAL Outlook Summary EMR Schedule June 2011 If EMR outer box is ready by April, we can send the 3 modules between April 18 and May 1 (ISIS break): Can we do that? Is there space to store the box? will be shipped separately. If EMR outer box is not ready by April, then we will send the 3 modules by June 13 and we will have two weeks to install it before the beam.
