Changes in development
  • TTCS Model philosophy change
  • Old EM ? 2 x QM ? 2 x FM
  • New EM ? 2x FM ? 1xQM
  • Start directly with FM manufacturing 
    integration of boxes prior to the QM
  • Skip the TTCS FM boxes performance testing at
    SYSU and send the boxes directly from INFN to
    CERN
  • Perform only performance testing on the QM box at
    SYSU
  • Advantages
  • FM boxes skip 2 transportations and 1 test
    campaign
  • Disadvantages
  • Risk (problems will show up in FM and not in QM)

6
Changes in development
  • Procurement is streamlined
  • SYSU budget located at CERN
  • Procurement communication directly from NLR (J.
    van Es) to supplier to avoid miscommunications
    and out-of-date numbers.
  • Sauro Bizzaglia sends plug and play faxes to
    suppliers and co-ordinates the CERN internal
    communication with procurement officers

7
System Design
  • Accumulator control and emergency heaters are
    combined in order to cope with electronic filter
    issue
  • Combined heater is 37.5 Watt
  • Impact
  • Better control for cold cases (large heat leak
    cases)
  • Reduction of thermostats on accumulator heat pipe
  • Less complex safety analysis
  • Accu ground test heater combined into one heater.
  • Accu ground test heaters are protected by
    Pt1000s, pressure relief valve and pressure
    monitoring. Thermal Switches deleted.
  • System EM testing on-going at SYSU
  • Condenser results
  • m-g testing started
  • Tube design is on-going

8
Last Box Design Issues
  • Design (drawings) work is shifted to NLR as no
    capability elsewhere is available
  • Manufacturing drawings detailing on-going
  • Internal tubing secondary box need to be adapted
    for proper two-phase flow in ground testing
  • Details on bracket designs updated
  • Bonding of box to USS and box components.
    Definition of surface treated (alodined
    surfaces) on-going.
  • Plate bending radii to be changed
  • Change box rib design to allow for AIDC cabling
    proposal
  • Cabling design by AIDC on-going supported by
    Lucio Accardo

11
Box integration functional check
  • Integration framework and procedure formats are
    delivered (NLR)
  • SYSU, NLR, INFN and AIDC can work on integration
    procedures
  • Identification of possible problem areas in
    integration
  • Cutting and welding accumulator feed line
    (addressed by Miaoh Tieh welding company)
  • Orbital welding of dead end components (argon gas
    flow)
  • Connection Pt1000s to external tubing
    (protection during transportation)

12
Box integration functional check
  • TTCB Functional check
  • Overall set-up is agreed with Electronics group
  • H/W for FM TTCB testing TTCE QM CAN I/F PC
  • H/W for QM TTCB testing TTCE EM2 CAN I/F PC
  • Mechanical set-up of is defined by NLR (Aswin
    Pauw)
  • Labview program set-up with operating interface
    with NI DAC is delivered to AIDC and explained
    (Aswin Pauw). Program runs at AIDC.

13
Component Progress Pump
  • EM pump runs successful in SYSU Engineering Model
    Loop
  • Pre-weld QM and FM tests upto completion
  • Delivery end early November
  • Pump license (update) is almost ready (one last
    signature is needed and is a formality)
  • Pump Functional check set-up is built by NLR
  • Ready end of October
  • After testing the set-up will travel with pumps
    to AIDC

14
Component Progress Accumulator
  • Manufacturing EM2 upto completion
  • Peltiers to be integrated
  • Proof and burst pressure testing on welded
    container performed
  • with representative spot welded part of wick
    material at inside
  • without fan structure
  • QM/FM activities
  • Brackets under manufacturing
  • Integration of accumulator on-going
  • Coming up
  • Built Accumulator acceptance test set-up at SYSU

15
Component Progress Condenser
  • A huge effort with contributions from
  • AIDC See Separate presentation!
  • NLR
  • INFN
  • Activties
  • EM-condensers are manufactured delivered and
    tested in the EM-loop at SYSU (see separate
    presentation)
  • 1 EM condenser has been subjected to a thermal
    cycle test
  • No performance degradation has been detected
  • FM drawings upto completion (this week)
  • Coming up
  • Wire heater soldering tests
  • Additional manifold soldering tests

16
Component Progress Heat Exchanger
  • All heat exchanger Inconel 625 plates are
    manufactured
  • Weld test to determine weld parameters are
    performed (Miaoh Tieh)
  • Coming up
  • Soldering test needed for soldering wire heaters
    to the Heat Exchanger

17
Component Progress Heat Exchanger
  • Heat Exchanger brazing tests with Inconel plates
    has been performed.
  • Although EM-brazing tests a NLR showed no
    problems. The brazing tests with Inconel plates
    showed locations of no connection. Possible
    causes
  • Decreased flatness of plates during storage
  • Deformation during brazing
  • Too little brazing material available
  • Measures are taken for a new brazing test
  • Clamping mechanism to increase force during
    brazing
  • More solder to allow for slight deformation of
    plates

18
Component Progress DPS/APS Heater Assemblies
  • DPS/APS
  • Manufacturing FM and QM on-going
  • New housing manufacturing for more weld samples
    and certificates
  • Heater Assemblies
  • FM and QM manufacturing in
  • Tubes cold orbit heater on transport to AIDC
  • Tubes pre-heater to cleaning company
  • Soldering at Beijing soldering company

21
Planning
22
Conclusion
  • Great progress on condensers
  • Major tests were performed successfully
  • Last design updates are updated and ready and of
    the week
  • FM Manufacturing can be started
  • Great progress box integration preparation
  • Last details on components and box design take
    more time then planned. Detailed drawings need
    all information.
  • Model Philosophy change resulted in a planning
    which is in-line with the overall integration
  • Planning is tight and relies on few key
    personnell

23
Points of concern
  • Delivery of transport tubes to CERN
  • No design available yet
  • To keep the schedule flexibility of all involved
    parties is needed
  • Components procurement
  • Thermal switch lead time
  • Focussing many tasks on few personnel because
    broad knowledge of TTCS is crucial for tasks
  • TTCS Box Design and drawing finalisation (NLR)
  • Design drawings transport tubes (Alvino/Gargiulo
    and drawings NLR)
  • Procedures set-up and close support (NLR)
  • Procurement (NLR)
  • System design and Project Management of all
    parties (NLR)
