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

GGLASST Project4

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

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

GGLASST Project7

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* Base Frame with wire rope isolators

OSC* CoverOSC* breather valves

* OSC Cribbing removed and Cover transparent for clarity

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)

GGLASST Project9

1. Cribbing has been added to the OSC Base Frame to prevent any contact during air shipping

• 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)

OSC changes

• OSC changes, after technical discussions with SLAC1. Added Cribbing2. Changed relief valves

GGLASST Project10

• OSC changes, after technical discussions with SLAC1. Added Cribbing2. Changed relief valves

2. 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

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 scfm2 valves at 1.7 psi (below design limit pressure) = 12.8 scfm

OSC changes

Flow rate requirement: 5.6 scfm

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)

GLAST LAT Project CU Meeting, Apr 17, 2007

CU @ SLACCU @ 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

GLAST LAT Project CU Meeting, Apr 17, 2007

ConclusionsConclusions

• 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
