  1. GLAST-LAT Calibration UnitShipment to SLAC Plan Review Luca Latronico luca.latronico@pi.infn.it Alessandro Brez brez@pi.infn.it Michele Pinchera michele.pinchera@pi.infn.it April 17 2007

  2. Overview • Meeting Goal • Activities Schedule • Shipment Issues • CU-ISC/OSC Shipping Configuration • Shipping Plan • OSC changes • Handling/Assembly Issues • PHT and assembly documentation • CU vertical operation options • Receiving Tests

  3. Meeting Goal • Goal • Authorize shipment of the CU to LAT-ISOC at SLAC • Calibration Unit Flight Hardware Handling Plan • LAT-PS-08131, approved april 14 2006 • Describes CU Integration and Test at INFN-Pisa and CERN • Original plan was to de-integrate CU at INFN-Pisa and ship single modules back to SLAC • Current plan is to send the integrated CU • Technical discussion between INFN-Pisa and SLAC provided support documentation and minor modifications to allow the CU shipment • CU will be operated at ISOC as a test-bed

  4. Shipping List • Calibration Unit • Integrated in ISC and OSC assemblies • EGSE • GASU, VME crate, PCs and DAQ network • MGSE • Rotation stand, integration and handling tools

  5. Calibration Unit Description - reminder

  6. Activities Schedule • Shipment from INFN-Pisa on 23th April • Transfer by truck from INFN-Pisa to FCO (Rome) Airport • Arrival to SFO by 28th April • Flight from FCO to SFO with carrier Delta Air Lines • CU incoming test during ISOC workshop (30Apr-2May) • INFN-Pisa team support

  7. CU-ISC/OSC Shipping Configuration • CU will be shipped as an integrated detector, not as single TRK and CAL module as foreseen in the original plan (ref. LAT-PS-08131) • Technical feasibility was discussed in previous engineering meetings between INFN-Pisa and SLAC OSC* breather valves OSC* Cover CU inside the ISC OSC* Base Frame with wire rope isolators * OSC Cribbing removed and Cover transparent for clarity

  8. Shipping Plan • Shipping plan from INFN-Pisa to SLAC • Shipment from INFN-Pisa to FCO on 23th April • Transfer by truck from INFN-Pisa to FCO (Rome) Airport (Shipper MACROS) • Transportation and storage arranged to minimize environmental stresses on CU • Flight from FCO to SFO by 28th April • Flight from FCO to Atlanta with carrier Delta Air Lines (Shipper MACROS) • Flight from Atlanta to SFO with carrier Delta Air Lines (Shipper MACROS) • Transfer from SFO to SLAC by 30th April • Transfer by truck from SFO to SLAC (Shipper American Overseas Air Freight Inc., TBC)

  9. OSC changes • Cribbing has been added to the OSC Base Frame to prevent any contact during air shipping • OSC changes, after technical discussions with SLAC • Added Cribbing • Changed relief valves • The OSC is provided with 12 CARIBUL – wire ropes ACX8/16/120/100 for shock isolation • The maximum lateral movement of the ACX8/16/120/100 (OSC cover) is less than 65mm • The new Base Frame Cribbing have been designed to permit a clearance of at least 70mm • The appendances don’t interfere with the swivel hoist rings, however they can be easily removed before handling Cribbing (Aluminum 6082-T6)

  10. OSC changes • OSC changes, after technical discussions with SLAC • Added Cribbing • Changed relief valves • The two breather valves used for INFN-CERN transportation by truck (AGM-TA-240-10-10-R) have been changed with two Halkey-Roberts 990RPV 05 05 (used for TRK air transportation) to satisfy the transportation by air flow rate requirements. OSC breather valves Flow rate requirement: 5.6 scfm • Min flow rate at the design limit pressure of the OSC: • Design limit pressure of OSC = 1.74psi (yield stress SF=3) 1 valve at 1.7 psi (below design limit pressure) = 6.4 scfm 2 valves at 1.7 psi (below design limit pressure) = 12.8 scfm

  11. CU Packaging Handling Transportation and Assembly documentation • Documentation provided by INFN-Pisa • Location link: http://glast.pi.infn.it/mech/beamtest/Deliverable/ • Documents tree link:_Deliverable_Documents_Tree • Technical notes • 13mar07_CUshipment_rel2 • Addendum to CU OSC_10Apr07 • CU ISC/OSC Packaging Handling Transportation Procedure • LAT-PS-XXXX-01 CU PHT Procedure • ISC handling-information-V02 • OSC NO-cribbing handling-information-V02 • OSC with-cribbing handling-information-V02 • CU Assembly Procedure • INFN-LAT-MECH-008-03 INFN CU ISC Assembly Procedure • INFN-LAT-MECH-009-01 INFN CU OSC Assembly Procedure • Applicable documents and drawings (LAT/INFN)

  12. CU vertical operation options • Proposed options (ref. Addendum to CU OSC_10Apr07) • CU on 1x4 rotation stand • CU-ISC as it is on modified 1x4 rotation stand • CU-ISC as it is on LAT rotation stand • 2. CU-ISC as it is on modified 1x4 rotation stand • 1. CU on 1x4 rotation stand Base frame bolted to Base Plate Shaft with rectangular flange Rotation Stand Frame Spacer VME PS EGSE Stand GASU PS transf.

  13. Receiving Tests • CU incoming test during ISOC workshop (30Apr-2May) • INFN-Pisa team will perform receiving tests • and support handling operations • subsystem level charge injection tests will be performed on single modules • TKR Noise&Gain, as per LAT-PS-03290 • TKR Noise occupancy, as per LAT-PS-03290 • Full CAL CPT as per LAT-PS-03287 • CR data taking will be run as a system level test • Cosmic rays data taking (end2end test BT2 - TKR, CAL LO, CAL HI trigger enabled)

  14. CU @ SLAC • Delivery from Pisa to SLAC/ISOC (building 33) • Upon arrival CU will be stored in the clean room where the LAT was integrated • post-ship tests will be performed by Pisa • will use EGSE (hardware/computers) delivered with the CU for testing • standalone set-up will not be connected to the SLAC network • Results • will be stored in CD/DVD • Testing @ ISOC (building 84) • Evaluation of facility, MGSE , and EGSE • SLAC engineers and technicians will evaluate if facility, MGSE and EGSE need to be modified • after assessment CU can be transported into ISOC facility • Facility • ISOC will ensure environmental monitoring/controls and earthquake safety are adequate prior to installation • MGSE • CU support structure may require modifications to allow data taking in horizontal and vertical positions • EGSE hardware • CU will be instrumented with other existing DAQ units • SIU, EPU, etc. • EGSE software • decision to test with FSW depends on manpower available to adapt test scripts to CU hardware configuration • this can not interfere with current FSW priorities • operation requirements will be revisited From Eduardo

  15. Conclusions • CU and associated EGSE, MGSE shipped as a single detector to SLAC • Will serve as a LAT testbed at LAT-ISOC • No need for further integration • Some modifications to MGSE required for vertical operation • All technical issues for shipment addressed and resolved with SLAC concurrence in techincal meetings • Solutions for vertical operations suggested based on experience at INFN-Pisa • Under evaluation by SLAC
