Pixel Detector ATLAS Prototype Service Quarter Panel and

Pixel Detector ATLAS Prototype Service Quarter Panel and Forward Disk Section update ID Week February 2006 System Test DAQ E. Anderssen LBNL

Pixel Detector PQSP Status and Plan ATLAS • Work at LBL is complete and it’s being packed up. • Expect to ship from LBL this Friday (Feb. 17) to arrive at Bat. 154 in about one week • LBL personnel( tech, student, senior citizen) arrive about Feb. 27 to set up Cirris tester and do reception testing of electrical connectivity • Loading of fibers and opto-boards and subsequent testing, checking interface with cooling parts is next critical step (and should happen in parallel) • Need validation of design/fabrication of PQSP optical items by end March to maintain schedule for production quarter service panels • Goal is to deliver first production SQP in April. HEX will be limiting factor unless something found in optical mounting. February 2006 System Test DAQ E. Anderssen LBNL 2

ATLAS Pixel Detector Vvdc at PP 1 • • First 4 harnesses made before pinout was finalized (affects 16 lemo power connectors) Terminal Blocks for Vvdc Replaced – Vvdc and Vvdc Sense routed thru 1 of two Lemo connectors • Jumpers are designed and will be fabricated which remap these to ‘Production’ PP 1 pinout – Should be delivered ~ April • QA Testing likely needs to be done with old pinout due to schedule constraints February 2006 System Test DAQ E. Anderssen LBNL 3

ATLAS Pixel Detector PSQP PP 1 as completed • This will be the shipping configuration of the PSQP • For Acceptance Testing, the PP 1 B panels are welded to the base, but will be held at R 450 in the test • This fixture may be used in system test, but will require some modifications for gas seal February 2006 System Test DAQ E. Anderssen LBNL 4

ATLAS Pixel Detector Optical Service loading configuration • • All SQP’s held inverted to allow population of PP 1 penetration with Ribbons Previous slide shows backbone reinforcement required to flip panels Opto-heat exchanger shown installed underneath backbone (on top in this picture) ENV feedthru removed for this operation February 2006 System Test DAQ E. Anderssen LBNL 5

Pixel Detector Environmental Sensors ATLAS • • • Env connectors (4 lemo’s worth) wired in thru ISP slot Internal locations all terminated with 2 -pin connectors—blue pads in foreground of right pic Do not have NTC’s or Humidity sensors at LBNL—will need to install of them here – May need some E-tech (someone who can really solder) time from an institute to facilitate this February 2006 System Test DAQ E. Anderssen LBNL 6

Pixel Detector Use of Spares ATLAS • Spares in the production SQP’s are fully wired ‘PP 0 Boards’ (serves up to 6/7 modules)—all connected at PP 0 and PP 1 electrically • Spares used in event of broken internal SQP components/connectors/pins etc • Only work if fully serviced with appropriate flavor of Optoboard, and if they are fully servicable externally • Discussion of what level of external infrastructure needs to be present to use Internal Spares might be an appropriate exercise for this group • Infrastructure is of course both physical services, but can also affect software/DB modularity as use of internal spares changes external mapping/modularity February 2006 System Test DAQ E. Anderssen LBNL 7

Pixel Detector Disk Status ATLAS • This is not my responsibility—so this represents only my limited understanding of the status • Defer to Gil for scheduled completion • Preparation for electrical QA testing underway in recently occupied clean room • As of yesterday—all disks populated with sectors, preparation of auxiliary tooling underway to mount U-tubes —first U-tube mounted, but need to align sector tubes to install remaining • Delivery of PEEK fasteners allowed mounting of all strain reliefs (tube and cable) to all disks • Should be mounting and inserting first disk in End frame this week—only a test as no capillaries are available • Believe we are on schedule for April delivery, but capillary is on CP (Gil? ) February 2006 System Test DAQ E.
