Scalable Kilo-Pixel MKID DAQ for Cosmology A DAQ for x10K MKID pixel array requires: Signal generation of thousands of frequency tones to excite the MKID resonators. 4 GHz of RF bandwidth per RF feedline. 60 GB/s of raw data into ADCs 80 GB/s of signal generation 140 dB of ultra low noise amplification. Up and down RF frequency conversion Multiple 1K-channel live data streaming. x1000 FPGA based data crunching. 10 K MKID pixel array 1Gb/s data storage (photon catalog) (B. Mazin, UCSB) 3 Alan Prosser | DAQ and Trigger R&D Overview 10/27/2014

Rad Hard Sensor R&D for HL-LHC 3D sensors have electrodes etched in the silicon substrate FBK 11-26-01 on a PSI46Dig SINTEF on a PSI46 Analog Efficiency 98.8% Efficiency ~95% • 3D sensors are one of the most promising technology to withstand the very high radiation doses expected at the HL-LHC • Fermilab test beam tested irradiated samples up to 3x10 15 neq/cm 2 . Efficiencies for those samples are around 90% 5 Alan Prosser | DAQ and Trigger R&D Overview 10/27/2014
DAQ for Sensor R&D Fermilab Test Beam Facility DAQ: • Old pixel telescope DAQ is based on CAPTAN • Triggered, 1cm 2 coverage, and 8µm track resolution • New strip telescope completed in FY14 is based on CAPTAN too • Dead-timeless, 16cm 2 coverage, and 5µm track resolution Other DAQ: • For the last 10 years firmware and software from CAPTAN project supported collaborations within Fermilab, U.S. collaborators at Colorado and Purdue, and Italian collaborators in Milan, Lecce, and Torino. 6 Alan Prosser | DAQ and Trigger R&D Overview 10/27/2014
12 Channel Array Optical Transmitter Module (ATx) (SMU) • ATx is a compact (1.9 cm x 2.2 cm x 0.44 cm), radiation-tolerant, 12-channel array optical transmitter module towards 120 Gbps optical link, integrating array optical components, a VCSEL array with a driving ASIC in a custom transmitter module. • A custom low-cost and reliable “active - alignment” method was developed to solve the challenging alignment issue in the array optics area. • With a commercial VCSEL array driver, the ATx module successfully operated at 10 Gbps/ch and aggregate data rate of 120 Gbps. The optical transmitter eye diagram passed the eye mask, and the transmitted BER less than 10 -12 was achieved at 10 Gbps/ch.
