5Changes in development
- TTCS Model philosophy change
- Old EM ? 2 x QM ? 2 x FM
- New EM ? 2x FM ? 1xQM
- Start directly with FM manufacturingÂ
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)
6Changes 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and out-of-date numbers.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
7System 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
8Last 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

11Box 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)
12Box 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.

13Component 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
NLR Pump Functional check set-up
14Component 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
15Component 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
16Component 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
17Component 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
18Component 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

- To be done
- Attach (weld) hydraulic connectors to evaporators
- Cleaning of tubes prior to final integration
(procedure is delivered to Eric Perrin)
20Component Progress Transport tubing
- Design on-going upto finalisation on 6 November
(by Antonio Alvino supported by Corrado Gargiulo) - To do
- Transport tubes on transport to be cleaned
- NLR will make manufacturing drawings of tube
design - Manufacturing of bending tools (AIDC)
21Planning
22Conclusion
- 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
23Points 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)
