Prototype Service Quarter Panel and Forward Disk Section update

1. Prototype Service Quarter Panel and Forward Disk Section update ID Week February 2006

2. PQSP Status and Plan • 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. E. Anderssen LBNL

3. Vvdc at PP1 • 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’ PP1 pinout • Should be delivered ~ April • QA Testing likely needs to be done with old pinout due to schedule constraints E. Anderssen LBNL

4. PSQP PP1 as completed • This will be the shipping configuration of the PSQP • For Acceptance Testing, the PP1B panels are welded to the base, but will be held at R450 in the test • This fixture may be used in system test, but will require some modifications for gas seal E. Anderssen LBNL

5. Optical Service loading configuration • All SQP’s held inverted to allow population of PP1 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 E. Anderssen LBNL

6. Environmental Sensors • 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 all of them here • May need some E-tech (someone who can really solder) time from an institute to facilitate this E. Anderssen LBNL

7. Use of Spares • Spares in the production SQP’s are fully wired ‘PP0 Boards’ (serves up to 6/7 modules)—all connected at PP0 and PP1 electrically • Spares used in event of broken internal SQP components/connectors/pins etc • Only work if fully serviced with appropriate flavor of Opto-board, 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 E. Anderssen LBNL

8. Disk Status • 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?)
