Solenoids
• Contract for Production and Detector Solenoids placed with General Atomics in CA
• Commercial bids for Transport Solenoid modules under review
• Prototype TS module test at CHL delayed due to compressor failure– ~1 month recovery, re-start
cooldown 22-JUN– Successful test ->
Production Readiness Review -> Place TS contract
• Seeking out alternatives to CHL for production module tests

Scan at near end only Read out at both ends
<#PE>/MIP = 85
Exceeds requirement by a factor of 1.8
Detailed studies of detector response
underway

Other recent highlights
• Review of remote target handling in March– Focus now on air handling, contamination control, robot design
• Software/computing review in March• Test of CsI (alternative) calorimeter prototype with 100 MeV
e- beam at Frascati in April– Time resolution exceeds requirements, E resolution OK
• AlCap test beam (+Al23 X) at PSI– Optimize internal shielding, STM– Finalize p multiplicity, E spectrum studies now– Additional run in fall for n multiplicity studies
• Prototype straw tracker panel built– Leak checking now, vacuum testing next

Summary
• Good progress since last AEM– Received CD2, cost/schedule/scope now baselined– Long lead items (CD3a, 3b) are go
• 77 km of superconducting cable starts to arrive this summer• Solenoid fabrication starts next year• Experimental hall construction started
• Next major milestone is CD3c in spring 2016– Major simulation campaign underway (14M CPU-hrs)
• Running >10k jobs per day on OSG• Excellent support from SCD
– More design reviews, detector prototyping, beam tests
