5 ANNEXURE 1 Technical Specifications for Fabrication and testing of a SS UHV chamber and as per given drawings Tender No: IUAC/ NIT/18/SKS/ Scope of work 1. Drawing, fabrication, testing (where necessary) and supply of the Quadrupole cryostat UHV chamber as per given drawings. 2. Fabrication drawing:- Contractor has to prepare the fabrication drawings as per IUAC supplied design. A hard copy as well as soft copy of the drawings will have to be submitted to concerned technical personnel and after due approval only fabrication can be started. 3. Material supply: - The quadrupole cryostat UHV chamber incorporates many components out of which some are of general nature available in Indian market and some are of very special nature & hence need to be imported. The components that are to be imported are listed in Annexure III along with the make & part number. IUAC will provide the custom duty exemption certificate. The contractor has to provide all the other materials which include all the MS materials for joining the yoke assembly, SS-304L for helium vessel and pipes attached to it and SS-304 material for vacuum jacket material, the tubes and pipes as required in the fabrication as per supplied drawing for the helium Dewar and the vacuum jacket. Aluminum of grade 1050/1100 (certified by independent testing laboratory) for 50K shield, OFHC copper for the Helium Recondenser & Re-liquefier, all the different sizes of SS bolt and all the vacuum flanges (KF, CF) at the vacuum jacket and all the vacuum ports are to be covered with blind flanges and appropriate gaskets before shipment along with 2 sets of additional copper gaskets each. All Viton O-rings required for the assembly of cryocooler to the cryostat would have to be supplied in double sets. The MS stand and all MS parts will have to be powder quoted with light Grey color paint. All the materials have to Certified by Government testing laboratory. 4. The helium chamber will have to be cleaned for high vacuum and shining by mechanical polishing from outside. The vacuum jacket will be electro polished from inside and shining mechanical polishing from outside. The Aluminum material has to be handled carefully so that no scratch grease or dirt is accumulated during its assembly. It is desirable that the workers always use clean cotton/rubber gloves during the assembly of the cryostat so that grease and dirt do not find their way into

6 the chamber which ultimately degrade the vacuum and also increase the heat load due to gas conduction. 5. Guarantee : - The cryostat shall be guaranteed for 12 months from the date of acceptance against any material and manufacturing defects. The defects that may arise during the guarantee period shall be rectified at IUAC site and necessary tools, manpower to be arranged for attending the defects in a reasonable time. 6. Testing : - Since the chamber will be made partially at the factory so all the small-assembled components that need helium leak testing will be done at factory site. A pre-assembly test with/without magnet and the iron yokes is planned at factory site to understand all the difficulties during actual assembly and also see the working feature implementation is planned before shipment to IUAC. The cryostat will then have to be assembled at site in stages (as can be understood from the cryostat detail). After the assembly, the chamber will be subjected to leak testing. All leak testing has to be better than 1x10-9 Torr Ltr/sec helium, under vacuum testing. Then the cooldown will follow with operation of IUAC provided GM cryocooler and also liquid helium and after the cooldown other aspects of the cryostat features will be tested such as its maneuverability in all the directions even in cold condition. Vendor should guarantee that there will be no touching between the shields when the system cools down to low temperature and the designed flexibility are maintained at low temperatures and also the vacuum integrity of the cryostat is maintained at room temperature and at low temperature of 4.2 K. The vendor should guarantee the cryogenic system & vacuum vessel must be capable of maintaining a vacuum of 10-4 Pa (7.5x 10-7 Torr) or lower vacuum at cold condition (4.2K) and also a leak free( leak rate<1x10-9 Torr Ltr./sec) system. The heat load aspect will be IUAC s responsibility. 7. This note describes the cleaning and welding procedure to be used on magnet cryostats. This note also describes the clean condition required for welding that occurs within the CRYOSTAT assembly area. GENERAL The vacuum vessel for the superconducting magnets must be designed as a 0.1 MPa (1 bar or 15 psig) pressure vessel (internal pressure). In addition, the magnet vacuum vessels must be designed for an external pressure of 0.1 MPa (1 bar or 15 psig). The helium cryogenic vessels for the magnets must be designed as a pressure vessel with a working pressure of 0.4 MPa (4 bar or 60 psi) under the ASME pressure vessel code (or the equivalent European of British standard code) for nonflammable gases. Piping must be designed for a working pressure of 2 MPa (20 bar or 30 psi) unless otherwise specified.

7 COMPONENT CLEANING IN PREPARATION FOR WELDING:- Before CRYOSTAT components can be welded, the surfaces of the components shall be cleaned after manufacture and rendered free from all traces of cutting fluids, grease and other hydrocarbon contaminants. The parts shall be cleaned according to the following procedure: detergent solution n ultrasonic bath of heated alkaline After cleaning and drying a local wetting test on a visible external surface shall reveal a film of water covering the wetted surface without showing single droplets. After the cleaning of the parts has been completed, they shall be bagged protecting the surfaces from scratches, contamination and dust. The parts should be tagged and put into locked storage. WELD PREPARATION : - The area machined in preparation for welding shall be free from any traces of cutting fluids or contamination. The machined surfaces shall also be inspected and free of cracks, holes, and porous regions. WELDING METHODS TIG, MIG, or plasma welding methods shall be used. All leak-tight welds shall be fully penetrated. The number of weld passes made while welding a component depends on the degree of distortion control needed during the weld process as well as the size of the weld. Distortion due to welding may be a problem for a number of the welds in the CRYOSTAT. It is recommended that the distortion of the welded sections be measured as the welds are being made, so that corrective measures can be taken to reduce the weld distortion of the finished components. All welds shall be made using a shield gas to prevent the formation of slag and porosity that may interfere with the tightness of the weld. Tubes that are welded must have an inert purge gas flowing through the tube as the weld is being made. Automatic welding techniques (for example, orbital welding) are recommended for welds made on circular pipes and tubes. If manual welding is used, non-destructive tests shall be used on 100 percent of the welds. A dye penetration test should be done on the filled section of a full penetration weld before the surface of the weld is finished. All longitudinal welds in the CRYOSTAT components must have a radiographic inspection. The only welds on the cryostat that do not require a radiographic inspection are the final close out welds, that cannot be inspected using radiographic inspection. These welds must be

8 tested using a dye penetration test. If automatic or orbital welding techniques are implemented on helium piping then the percentage of non-destructive tests can be relaxed to meet the normal standards for the weld being made. A fully qualified welding inspector must do all non-destructive weld tests. Vacuum welds need to be done from inside to avoid traps of poorly pumped volumes. WELDING PROCEDURE QUALIFICATION AND TESTS:- The 304 stainless steel cryogenic vacuum vessel full penetration welds in plates that are from 12 mm to 25 mm thick. The samples, which are at room temperature, shall be visually inspected. Dipping them into liquid nitrogen until the boiling stops shall thermally shock the samples. The sample shall be allowed to warm to room temperature while sitting in air. The cold shock shall be repeated 3 times per sample. The welds shall be visually inspected. The pipe weld samples shall be subjected to vacuum leak tightness tests according to the standards set for, in reference. 8. Vacuum leak check procedure: - All the components that will undergo the MSLD leak tests will have to follow some determined procedures which is described in a detailed format (attached herewith) titled MICE Vacuum Test Procedure. 9. Workmanship & cleanliness : - The supplied chamber should have excellent workmanship in all the aspects of fabrication. The cleanliness is of paramount importance in this fabrication and a clean isolated bay area should be assigned for this job. The floor can be fine screened concrete or equivalent. The floor must be adequately painted or sealed so that the floor is not a source of dust or other contaminants. At no time during the assembly the inner chamber should be touched by bare hands and all the personnel handling this job should ensure that they wear clean gloves before touching any components which goes inside the cryostat. So we presume that enough supply of good quality hand gloves are ensured and will be provided by the vendor both at their factory level as well as for the work at IUAC site. 10. Plan of action and assembly fixture : - It is mandatory for the vendor to submit a plan of action for the job (how he wants to approach the execution of the job and any technical deviations there has to be mutually agreeable to both parties) and he must plan for some assembly jigs, which will be needed till the total fabrication is over. 11. Site assembly : - The final assembly will be done at IUAC site. Except Vacuum pump, leak detector and the welding machine, Vendor has to arrange for all the required consumable items needed for the assembly (argon gas, etc.) which are otherwise not mentioned in this tender document. One good welder, one helper and one supervisor (who will be working with the project work) are at least required for the job at site and since the assembly will be done in stages (which also includes final testing), at least a stay of 2-3 weeks at site is envisaged at this point of time. IUAC does not provide for stay of vendor at its campus site, and vendor has to arrange suitable accommodation at his own in New Delhi.
