STAR HFTOutline
• Existing HFT/PXL status and schedule• Testing Goals at IPHC• Immediate plans / discussion• Possible scenarios for the near term
3IPHC meeting – May 7, 2012L. Greiner
STAR HFTExisting PXL status and schedule
• CD-2/3 passed September 2011 – we are a fully funded DOE construction project.
• Many thanks to IPHC group for years of collaboration, support and help including during reviews.
• Significant management overhead, reports, reviews, etc.
• The main task for 2012 is the construction and delivery of a three sector prototype detector by January of 2013.
4IPHC meeting – May 7, 2012L. Greiner
STAR HFTSelected HFT Tasks for the next year
• Installation of the new IDS pieces and new beam pipe in ~ July 2012.
• Production of a prototype PXL detector using complete mechanics, installation tooling, sensors, RDO system, interface to STAR. This will allow for both an in beam test of the PXL design and a measurement of the charged particle environment at low radius.
• The installation for the PXL prototype detector is scheduled for December 2012.
• The SSD and IST detectors are not scheduled to be installed until summer 2013.
5IPHC meeting – May 7, 2012L. Greiner
STAR HFTPXL tasks for 2012
We have a deliverable of a working prototype detector (3 sectors) to be installed at the end of 2012. Thus we need to produce first articles of all of the production stages for the final detector.
Tasks for 2012:• Production probe testing working for Ultimate sensors• Cable design complete with Cu conductors• New pre-production RDO (all boards) system working• Full firmware and software for data-taking• All mechanical designs complete and tested.• Mechanical structures fabricated.• Ladders => sectors fabricated + full scripted testing.• Metrology• Slow control system• Software for tracking using metrology data• Software for cosmic ray / beam testing tracking.• etc.
Outer ladders have a simple rectangular driver region PCB.
Inner ladders have a complex driver region PCB that incorporates a kapton flex region to allow the ladder interface connector to be routed to the top of the sector.

STAR HFTSTAR PXL Ladder PCBs
There are 3 PCBs to produce for the STAR PXL detector ladders.
Low Mass Ladder PCB – common for all laddersOuter Ladder Driver PCB – joined to low mass PCB and used for outer ladders.Inner Ladder Driver PCB – joined to low mass PCB and used for inner ladders.
There are 3 outer ladders for every 1 inner ladder.
In addition, we would like to start the process of building ladders with Aluminum conductor PCBs so we would also like:
10 Low Mass Ladder PCBs with ~25 µm Aluminum conductor

STAR HFTProjected completion dates
• Order Ultimate sensors: September 2011• First Ladder cable in FR-4: Oct/Nov 2011• First product probe testing: January 2012• Ultimate probe testing complete: February 2012• PXL RDO ready: April 2012• First prototype sectors: August 2012• Install Prototype detector: January 2013
