University of Pittsburgh: EOI Response

Interest: Testing and Quality Assurance for Cold Motherboards Design, setup, and operation of possible test-stand

People: Naples&Paolone, at least 1/3 of postdoc, and undergraduates

• Previous Experience (warm electronics)
• Design, layout, and testing of the 9U L1 Receiver system for ATLAS*
• Test-stand designed and ran at Pittsburgh
• Number of modules ~100 (+ several hundred sub-modules)
• MINERvA: Prototyping, procurement, and testing of several hundred readout boards

(FEB) and light injection (LI) calibration system.

• Test-stand designed and ran at Pittsburgh
• T2K(ND280): Responsible for the procurement(ASICS) and testing (done at FNAL)
• f the TRiP-t based front-end electronics (TFBs) for both the POD and SMRD
• Designed and built the power distribution, mounting, and cooling system for both

the POD and SMRD electronics.

• Presently working on design of custom 6U backplane and controller card for

electronics upgrade (based on PSI DRS ASIC) for NA61:

• US-NA61: Hadro-production measurements for DUNE to improve neutrino flux

prediction

Facilities: University of Pittsburgh

• The University and Department received a NIST grant for infrastructure

improvements a few years ago:

• HEP group now has new lab space (~4000 SF) specifically designed for

construction projects.

• The space includes a class 100,000 clean room, electronics and detector

assembly space.

• Machine Shop: The physics machine shop currently utilizes approximately 3400 SF

with a staff of three full time machinists.

• The shop was used extensively for the T2K electronics mounting and cooling

hardware including LI hardware for both MINERvA and T2K.

• Electronics Shop: The physics electronics shop utilizes 1400 SF of floor space. Two

full time personnel (EE/Designer and technician) are at the disposal of the HEP group and paid for by the University.

• Both were involved in the design, testing, and construction of the ATLAS trigger

electronics, MINERvA front-end readout electronics test-stand and both MINERvA and T2K LI control electronics and presently the USNA61 electronics upgrade.

Facilities: Short Equipment List

Machine Shop:

• HURCO VM20 W/4TH Axis Milling Machine: Large work envelope (40"x20"x20") and more complicated tool paths.
• HURCO VM10 Milling Machine
• HURCO TM10 LATHE
• MITSUBISHI BA8 WIRE EDM: Prototyping and small quantity production.
• Large lathe and horizontal boring mill: Adds production capability to shop.

Electronics Shop:

• Tektronix DSA71254B Oscilloscope plus high bandwidth probes: High bandwidth oscilloscope/digital serial analyzer.
• PACE ThermoFlo TF 2700 Area Array Rework and PACE XR 3500 X-Ray Inspection System: Soldering system for surface mount

devices plus X-Ray inspection system. This allows us to install and remove a wide variety of CSPs, FCs, PBGAs, CBGAs, MLFs, LCCs, and other SMDs.

• Tektronix AFG3252: Function, Arbitrary Waveform, and Pulse Generator
• OC White Pro-Zoom Microscope: Inspection microscope with high-quality camera
• National Instruments PXI Chassis, Controller, and Modules: PC-based platform

for test, measurement, and control.

Summary

• The Pittsburgh group has an Interest in Actively Participating in

the Testing of the Cold Electronics

– We have a history of warm electronics testing and design:

ATLAS, MINERvA, T2K, and US-NA61

– The department has made upgrades to our infrastructure: New

lab space, updated electronics and machine shop facilitates

• We'd like to exploit these resources
• In addition UPittsburgh has a Helium

recycling facility and we can exploit the available expertise.
