1. Peter Spiller MAC meeting 10.10.2011 Time Schedule SIS100 1

2. General – Status of Planning  First planning approach via the machine project leaders.  Discussion and agreements with technical departments.  Identification of (time) critical components and interconnetions between work packages.  Agreements on procedure, procurement strategy and boundary conditions for each main subsystem with technical departments.

3. Agreed Boundary Conditions  The required man power is available.  The milestone „building readiness“ must be met by each technical subsystems needed for machine commissioning.  The installation phase for the machine components is assumed to be one year.  The device status after the installation phase allows a commissioning with beam.  Rather than trying to complete ALL technical subsystems before comissioning, with the risk that commissioning is delayed, completion of the machine with an equipment which allows commissioning.  Depending on the device status beam comissioning may be done with reduced machine performance (e.g. lower ramp rate, lower beam intensities etc.)  If needed, the completion of the technical equipment (devices) can be made in dedicated shut downs in the following year.

4. Procurement Strategies – General Statements  In most cases, GSI does not provide specifications on the level of blueprints.  In such cases, the completion of the design has to be taken over by the contractor - accompanied by a number of design and integration reviews with GSI (defines time required before production can be started).  There are several technological risks which require in several cases the demonstration of the functionality of devices by means of pre-series components.  However, in order to save time, the preparation for series production must be performed in parallel to the production of pre-series components.  In the final phase of prdouction process of critical items, in order to meet the milestone „building readiness“ (plus installation phase), several work packages have to be excecuted in parallel (e.g. FAT, SAT, installation and commissioning without beam).  Focusing of resources on devices needed for beam commissioning.

5. Cryomagnetic Units Dipole Modules  Tendering started of 112 units – still ongoing.  Detailed specs., procurement strategy, time schedule and Werksvertrag (contract) prepared and completed.  Contracting of series production, including pre-series module for testing  Procurement strategy very similar to my last MAC presentation.  Production rate had to be increased to one unit per week (probably 2 shifts production).

6. Cryomagnetic Units Quadrupole Modules  Critical workpackage (84 units) – no inkind proposal  Procurement strategy similar to dipole module: Contracting of series including one pre-series module (of the arc) for testing the individual devices and the integration.  Completion of detailed specification until April 2011 (contracting in June)  Contract comprises: 1. completion of the design of all modules based on the existing pre-design (about 3 My) 2. design and production of one preseries module, including all components (quadrupole chambers and BPM will by supplied by GSI/FAIR) 3. production of series and FAT  Challenging: no 3 turn quadrupole, no s.c. steerer, no s.c. sextupole, no insulated s.c. wire has been built before  Allowed production time about 2 years (one module of 84 moduls per week) (two or three shift production > higher costs)

7. Example Quadrupole Modules

8. Power Converter - Substructure  Main Dipole Power Converter (1 unit) (german EOI)  Main Quadrupole Power Converter (3 unit)  Corrector Magnet Power Converter (about 200 units) Two procurement groups formed: Group 1: 168 Steerer PCs Group 2: Chrom. sext. PCs (6 units), Resonance sext. PCs (11 units), warm and fast Quadrupoles (4 units), s.c. inj./extr. Quadrupoles (4 units)  Septa Power Converter (6 units) (inclusing lambertson) – planning not yet made

9. Main Dipole and Quadrupole Power Converters: Commissioning without completion of load, the cryomagnetic system is not possible. Delivery with direct installation in the supply buildings. SAT only after complete assembly of the machine. Consequently, taking the prodcution time into account the contracting and delivery must start „delayed. Corrector Power Converters (partly inkind contribution by India) s.c. magnets FAT with dummy load SAT and comissioning with assembled machine – two per day > 80 days in total. > Contracting and delivery postponed. n.c. magnets SAT may be performed with final load Power Converter Procurement Strategies and Boundary Conditions

10. Example Dipole Power Converter

11. Rf Systems - Substructure Devices needed for SIS100 commissioning:  Acceleration Systems (critical) (14 units)  Bunch Compression Systems (critical) (9 units) Devices with potential delayed installation and commissioning:  Barrier Bucket Systems (2 units)  Longitudinal feed-back systems (still ongoing beam physics discussion wether needed or not) Contracting  Design, integration, manufacturing of cavity, power amplifier, control (amplitude, eigenfrequency)  Power supply units (incl. PLC) supplied by GSI  Driver accelerator supplied by GSI (standardized)  Cavity synchronization and control system interfacing (EOI GSI)

12. Rf: Agreed procedure and boundary conditions  Contracting of the acceleration and bunch compression systems is needed around April 2012 (early start !). (if not a copy of the SIS18 system is build)  For the acceleration systems, an uncertainty is the availability of Ferrit discs with the desired properties (consequence e.g. reduced Rf voltage) (Test discs shall be orders immediatly from the former Philips Ferroxcube – now in poland)  It is required to postpone the series production after successful testing of the preseries system. In case of the barrier bucket system, both cavities will be built in parallel.  For the main production phase, two years can be accepted for each subsystem. This is a precondition for participation in the tendering process.  In case of any delayes: The beam commissioning can be performed with only a fraction of the acceleration systems and basically without bunch compression systems.

13. Example Acceleration Cavity

14. BI: Focusing on Devices needed for Commissioning Devices required for SIS100 commissioning:  BPM  BLM  Transformers (DCT, ACT)  Schottky pick-up  Profile grids + stopper („first turn diagnostics)  Catcher current measurement  Chambers and manipulators Devices with potential delayed installation and commissioning:  Field controle loop  CO feed back  Tune feed back  IPM  High current transformer DCT (Device with delayed installation and commissioning within 1-1.5 years. ) Each item substructured as:  Detector  Chamber  Manipulator  Electronics  DAQ (incl. Software)

15. Beam Instrumentation Procurement Strategies: BPM: Design and integration studies well developed. Will be tendered by FAIR/GSI and supplied to the contractor of the quadrupole modules. Contracting as series production with one pre- series BPM in advance for integration tests in the pre-series quadrupole module. Series components will be supplied piece by piece for integration into the quadrupole module. Begin of contracting not critical (middle of 2013). Transformers: Transformers (3 pieces) will be tendered and industrially produced. Integration into vacuum chamber with ceramic gap (etc.) at GSI or at external subcontractor. One special (novel) high current transformer will be „built“ and assembled at GSI. Begin of contracting not critical. BLM: Tendering or direct contracting with IHEP. Begin of contracting not critical. Grid + stopper (first turn diagnostics): Grid re-design and matching to new apertures of existing design solutions. Running process in the design office. However, may be taken over by industrial contractor for series production. Stopper: FLUKA calculation for design optimization planned. DAQ: Most of the DAQ systems will be supplied as inkind delivery from Sloweni for all machines.
