  1. Recent HBD FEM Test Result Sigma on the base line sample ~ 1 counts HBD preamp HBD FEM computer A D C VA L U E Digitized preamp pulse Sample number

  2. HBD FEE • Connect the amplify signals to the FEM. • Things need to be done • Check all channels • Check cross talk. • Signal analysis – total charge resolution etc. • Overall schedule will be driven by the new DCM daughter card. • We have question on the ALTERA Stratix GX power requirements Gbits serializer – contact manufacture. • It probably will go out middle next week to the PCB maker. • End of Feb to have prototype board back from assembler….

  3. Small prototype system schedule • Two HBD FEMs, clock fanout, backplane, clock master module are already exist. • We are buying enough parts for 5 additional FEM modules. • 5 FEM can readout 240 channels. • Full system testing need to be perform with optical module and new DCM daughter cards before assembly additional FEMs. • Power supply and rack already exist. • We are waiting for prototype of the new DCM daughter card and optical modules. • We expect no later than end of Feb for fully assembled prototype modules. • One set of module will be enough for small prototype run

  4. Full readout system • The procurement cycle the FEM parts for the full readout system are expecting to be around 2-3 months. • The PCB fabrication and assembly are around 1-2 months. • We could start buying majority of the components. • The final PCB fabrication and assembly will not start till full system readout test and final design review. • Estimate to be no early than end of March. • The schedule is very tight to have everything fabricated before May.
