L0/L1 simulation introduction Spasimir Balev /CERN/ 09.02.2011
Introduction • The goal: design of L0/L1 trigger logic under the specific physics needs of NA62 • The limitations: • L0 output rate: < 1 MHz • L1 output rate: < 100 kHz • Those rates should accommodate not only the main pnn trigger, but also the control triggers and eventually triggers for other physics tasks. • The simulation tools: • the evolving NA62MC [slow, but most accurate] • toy MC and FLYO
What do we need for L0/L1 simulation: • Define the content: properties of the main [pnn], control [efficiencies, background estimations…], and additional [for other physics tasks] streams input from Physics Sensitivity WG. • Input from sub-detectors WG: • what primitives can be defined? • at which level can be used? • Development of the main simulation tool – NA62MC: • how well the primitives can [and need to] be simulated?
Status of the simulation • Levels of signal simulation: • KINEMATICS • ENERGY DEPOSITS / HITS • REALISTIC PRIMITIVES after digitization and reconstruction • Status of the detectors in NA62MC: • RICH: PMT hits and reconstruction • CHOD: energy deposits; NO digitization and reconstruction • MUV3: energy deposits; NO digitization and reconstruction • LKr: energy deposits; digitization coming soon • LAV: energy deposits; reconstruction • STRAW: hits; update on digitization and reconstruction coming soon • MUV1/2: update on detectors implementation coming soon • IRC/SAC: energy deposits; NO digitization and reconstruction
Estimation of L0/L1 rates gradually add signals on top of the previous This is only the first step
