1. SU participation in nn bar Sam Silverstein

2. Who are we? Particle physics group  ATLAS  IceCube Instrumentation physics division  ATLAS L1Calo trigger  ATLAS Tile Calorimeter front-end readout  XFEL timing and trigger system  PANDA calorimeter readout 2

3. Effort and resources Christophe Clement David Milstead Samuel Silverstein Access to two electronics engineers Have a guaranteed flow of graduate students, could involve at least one physics Ph.D. student in LoI studies In-house seed funding possible for initial studies and prototyping Long term involvement contingent on external support for hardware 3

4. What are our interests Hardware  Front-end electronics  Trigger and data acquisition  Timing/trigger distribution Physics studies  Background estimates  Geant simulation 4

5. 5 Some of our previous work

6. ATLAS TileCal digitizer A/D conversion, pipeline, readout of ~10 000 PMTs Produced, tested and commissioned more than 2000 boards 6

7. ATLAS L1 Calorimeter Trigger 7 Digital jet-finding and data merging algorithms Custom backplane and crate infrastructure Leading role in topology upgrade for Run 2

8. XFEL Timing/trigger distribution Synchronous with 1.3 GHz RF Distribution over more than 3.4km Accuracy better than 5 ps (RMS) 8

9. Questions What do we want to build? What is the current simulation status? What is the time scale for funding? Status of the collaboration? 9
