  3. The reusable parts of the Babar detector at Slac • The Dirc Bar boxes • The Dirc central support tube and supporting system • The calorimeter • The solenoid • The Barrel Flux returns and doors • Component under discussion F.Raffaelli

  4. The reusable parts of the Babar detector at Slac F.Raffaelli

  5. The Dirc Bar boxes • The DIRC uses as a radiator has 144 quartz bars. • The length of the bar box is around 5 m and its weight is around 130Kg. • Each bar box must be extracted first in order extract the support structure of the Dirc. • A safe transportation needs a proper transportation box. • The transportation boxes must assures the control of acceleration, humidity and temperature level. • We need to specify the allowable temperature, acceleration and humidity range. • We need to acquire the mounting tooling and procedures for dismount and remounting them. The dismounting of the barbox is schedule in September 2010 F.Raffaelli

  6. The central support tube and supporting system. • The overall dimension are 6.7 m; the total weight is around 30 Ton. The structure can be disassembled in its main parts to be transported easily. The strong support is a complex iron structure described in the left picture. Given the complexity a set of procedures must describe the dismounting, mounting and the verification operations. The Transition Flange is a single aluminium tube with diameter of 1780 mm and a length of 500mm. The central Support Tube is a cylindrical aluminium assembly of 1790 mm diameter, 3350mm length and a radial thickness of 77mm F.Raffaelli

  7. Remarks. • The dismounting of these parts is scheduled for July 2010 (from Krebs planning). The tooling and the procedures are taken care by SLAC. • The group assigned to this task and the integration team should attend to this operation acquiring the know how to managne the subdetector unit. • We have to consider the convenience of dismount the support tube given the complexity of the unit. • For the shipmenent we do not see a particolar problems of size and weight. • A tagging procedure must be adopted with a photografich set of drawings documentation.

  8. The Calorimeter. • The calorimeter dimension are respectively 2 750 mm and 3850 the outer diameter and the total length. The weight is around 27.6 Ton. • It contains 6580 crystals with a shape of a truncated trapezoidal pyramid. The crystal are arranged in a aluminium barrel structure of 48 polar rows by 120 crystal in azimuth with an inner radius of 900 mm. The plan is to transport it as unit. F.Raffaelli

  9. The Calorimeter. • The disassemble procedure has been studied in detail and a supported storage structure is available at SLAC. • The transportation cradle must be made. • We evaluate the possibility to fit it in the dimension of an ISO container of 24” feet . Unfortunately are not adequate for the transportation. • The size of 20’ ISO marine container are: • External dimension         /internal dimensions • Lenght 6.058 (0, -6) millimetri /5.898 (0, -6) millimetri • width 2.438 (0, -5) millimetri /2.352 (0, -5) millimetri • height 2.591 (0, -5) millimetri   /2.341 (0, -5) millimetri • We need to get the tooling too. Some of them are not going to be use for the dsmounting operation from Babar, but can be usefull to remount it in superb. F.Raffaelli

  10. The Calorimeter. Four ears with adjustments mechanism restrain the calorimeter with the IFR A very detail procedure is describe in a presentation load transfer process4 We need to attend during the dismount phase of calorimeter to be able to mount again Load transfer tooling will not be used to dismount the calorimeter from Babar F.Raffaelli

  11. The Calorimeter. The calorimeter is pulled out. The calorimeter is handed a the connecting bars and the load spreader. F.Raffaelli

  12. The Calorimeter. The calorimeter is placed on the mounting cradle spoiled from mounting tooling and scaffolding. • We start studying the transportation cradle identify the various phases: • Transferring from the storage support to the transportation cradle • Transferring the unit on the truck. F.Raffaelli

  13. The Calorimeter. We set the overall dimensions 3500X3500X6000mm Position for the isolation F.Raffaelli

  14. Remarks • The specification on acceleration and temperature control must be elaborate to define the type of thermal and mechanical isolation needed. • Some tooling that have a directly interface with the calorimeter must be shipped, others we have to evaluate the convenience. • Again who will be in charge to remount the structure should follow the operations so the integration team. • Tagging the parts and tooling is necessary. • Documentation during the dismounting is necessary. • A study of the handling for the operation of shipping and receiving must be done.

Krebs BaBar Detector Disassembly and Disposal Master Project Schedule (v15) F.Raffaelli

  15. The Solenoid. • The magnet can be disconnected from the cryogenic systems, non welding connection were made in place. Actually seems that can be quite easily configured in the transportation mode. It is not documented with drawing the support of the magnet. • The magnet and its accessory fit in a lowered towing truck and the yellow transportation cradle is still available. • Actually is not clear if the cryogenic system will be replaced in the Super-B project. F.Raffaelli

  16. The Solenoid. I believe that the installation beam is the same of the calorimeter the support and pillar are may be different F.Raffaelli

  17. The Barrel return flux and doors. • It will be disassembled piece by piece and stored temporally in the hall with no any provision of packaging. In the past the components arrived in wood boxes by truck and ship. The weight of each wedge is around 40 Ton. Each of them can be transported using an open 40 feet container (Flat-rack). • The doors will be dissembled complete and will be storage in the same way F.Raffaelli

  18. Times schedule • We have to update the schedule, regarding the component foreseen for the Super-B project the time schedule is summarized in the table below: • As we concern storage area for this entire component is foreseen in SLAC F.Raffaelli

  19. Costs • The main cost regards the component that need to be send by ship. As a very rough estimation we can assume that to ship from SLAC to Livorno 40 ton component cost 8’000 €. The doors and the Flux return barrel total weigh is around 450 ton; the support structure of the Dirc is around 50 ton, The calorimeter is about 30 ton • which means that the cost should be around 100 000€. • The solenoid, the bar boxes ,the calorimeter and the aluminium parts of the DIRC structure, should be send to Italy using the C5 US Air Force airplane that was used in the past to send the magnet. • We mast add the cost of the truck transportation to bring the components to the final destination. • The total expenses for the shipping should not exceed 150’000 € that not include the magnet and the Calorimeter • A more precise price evaluation must be verified when will be set the transportation date with the specification F.Raffaelli

  20. Man power • Is necessary to have at least 2 INFN engineers following the procedures during the disassembly of the services of each detector component in order to record all the steps that will be useful for the reassembly. • During the design time of the transportation facilities will be necessary the work of 3 engineers and 2 mechanical designer for a period quite close to 1 year. These persons are necessary in order to follow the disassembly in SLAC task, the transportation logistic task, the design of transportation tooling and the design of the integration of the component in the Super-B detector. • This last task must be speeded up as soon as possible because it affect not only the work to be done on each component but also the layout of the experimental area and , more important, it could effect also the list of component to be shipped. For this reason a task force, made by at least 1 engineer and 1 designer, must be set up as soon as possible. • If the construction and the installation of the tooling needed for the shipping will be in charge of INFN it will be necessary the effort of 2 or 3 mechanical technicians for a period of 1,5 year. F.Raffaelli

  21. Storage • It will be useful to have a place in Italy in which will be possible organize the storage of the components received and their refurbishments, in order to check the integrity of the components. • This place should allow also the possibility to work on each component in order to fulfil the interfaces of the new detector design. • By the way that the new design in not yet available is difficult at this time to have an idea of the man power needed for this. • Tooling for unloading and handling the component should be present in this area. F.Raffaelli

  22. Components under discussion. • Up to now is not well known if the Cryogenic System of the magnet should be reused in the Super-B project. • If it will be the case other two 40”shipping containers must be added to the list in order to accommodate the vacuum pumps, cryogenic pumps, valves, external cooler etc, except the Dewar. • The shipment of these items doesn’t effect the rough estimation costs of the transportation task described above. Other components of cooling system like valve, control element etc could be useful to re-use to save money. F.Raffaelli
