Overview
LCLS presents detector challenges
Signal comes in large pulses (many photons)
Pulse rep rate at 120Hz
Dynamic range/ low noise
>requires significant R&D for new detectors
Detector programs: LCLS and LUSI

Based on LDAC comments LCLS
decided to:
Proceed with 2 D Detector program at
Cornell
Initiate a 2nd pixel detector at BNL (LUSI)
Start a streak camera project with LBNL
Assign detector projects to specific
experiments
Develop detector specifications matched to
experimental requirements
