(six numbers) of Superconducting Niobium Quarter Wave Resonators (QWR) along with their Niobium Slow Tuners Bellows [6 Nos. (six numbers)], 08 Nos. (eight numbers) of spare Niobium Slow Tuner Bellows, 02 Nos. (two numbers) of spare Niobium Loading Arms and 03 Nos. (three numbers) of spare Niobium Drift Tubes, as per the drawings, technical details and specifications attached. Each of the fully fabricated Resonator Assembly will be tested for vacuum tightness at IUAC. Subsequently they will be tested at low temperature for RF tests. The fabrication of superconducting niobium resonators is quite complex and involves several processes and facilities. Some of the fabrication processes will be carried out by the Bidder and some will be done by IUAC. While the machining, sheet metal forming, rolling, fitting of the niobium and stainless steel parts/ components / sub-assemblies and TIG welding of stainless steel parts/ components / sub-assemblies etc. will be done by the Bidder, the electron beam welding, electropolishing and heat treatment of the niobium parts / components / sub-assemblies and final testing (at 4.2 K) of the resonators will be done by IUAC. Thus the resonator parts/ components / sub-assemblies move back and forth between the Bidder’s site and IUAC several times during the course of the work. The details of the various processes / operations and responsibilities of the works are given in Annexure-C. The niobium components are to be machined to the final size and assembled within the tolerance prescribed. The Bidder should provide sufficient technical details about the machining, forming and assembly processes that he plans to adopt, and discuss the same with IUAC engineers and scientists before commencing work. General Description The main assembly drawing of the superconducting niobium quarter wave resonator is QWR-001-E. The superconducting resonator operates in high vacuum (< 10-8 mbar) at 4.2 K (~ -269 C), well below the superconducting transition temperature of niobium (9.2 K). The resonator is mounted in a cryostat, with the vacuum being common to both the cryostat and the resonator. During operation, the resonator is kept in the superconducting state by filling liquid helium in the central conductor (Loading Arm & Drift Tube assembly, please refer Bare Niobium QWR, and QWR with Slow Tuner Drawings) and the annular volume between the stainless steel outer jacket & the niobium housing. A superconducting resonator must produce a very large electromagnetic field (voltage of many hundreds of kilovolts) with a small amount of input power (few Watts). Under operating conditions several thousand amperes of RF current flows on the niobium surface of the resonator. A defect (e.g. an inclusion or weld porosity), even if microscopic in size, will produce RF losses that cause joule heating. If the region heats just a few degrees, to 9.2 K, it loses superconductivity and the resonator quenches, that is – it quits working. Therefore it is essential to have a niobium surface free of inclusions, fissures, folds, scratches and weld porosity. It is not possible to test resonator parts as they get fabricated. The only way to test fully is to complete fabricating the entire resonator and then try to operate it. At this point, defects, even if they are repairable, are very expensive, effort intensive and time consuming to fix. Therefore, if a problem is encountered Tender Document IUAC/NIT/13/SSKS/2014-15 Page 7 of 14 at any point during fabrication it is essential to: 1) stop the work, and, 2) call to IUAC's attention, so that a fix, if it is possible, can be worked out. The highest cost and greatest delays can result from "patching up" a job without full consultation with IUAC. After machining, forming and Electron Beam Welding (EBW), all parts of the resonator are chemically electropolished to remove approximately 0.2 mm from the upper layer of the surface of the niobium material. Inclusions embedded underneath the surface that are deeper than 0.2 mm, will not get removed during the chemical processing. Therefore it is very important to avoid deep inclusions. Machining, Forming & Handling of Niobium components & SS outer jacket fabrication and TIG welding (Bidder’s scope) Niobium is a soft material which is easily machinable by taking due care. High speed steel (HSS) tools are well suited for machining niobium. Carbide tools may also be used. All tools must be sharp to prevent folding of the niobium material while machining. Cutting oils free of sulphur are recommended for machining niobium for RF superconductivity applications. Cutting oils should be used only where they can be easily flushed out. Ethanol or Isopropyl alcohol should be used where cleaning would be difficult. Tools used on other materials should not be used for machining niobium. Exclusive set of tools, meant only for machining niobium should be used. Polishing of all niobium parts should be done by hand (no grinders!) using Al2O3 emery paper (220, 400, 600 grades) & Scotch Brite, to avoid smearing, folding and inclusions. Separate set of files, marked exclusively for niobium, should only be used. Machined parts must be handled carefully while sitting them up on tables/shelves. Niobium parts must always be set on clean paper. They should be packed properly in zip lock bags or using plastic cling film and/or aluminum foil. Tables and shelves must be kept clean and free of chips, dirt, sharp objects& tools. Niobium forms very similar to copper. When forming and rolling the sheet metal, the dies and rollers must be clean and free of oil, dirt and chips. Clean paper, such as tracing paper, may be used as a protective layer when rolling to avoid the rollers coming in direct contact with the niobium material. All fixtures used for holding niobium parts should be kept clean, free of oil, dirt and chips. Electron Beam Welding (at IUAC) All niobium welds are electron beam welds (EBW) performed in vacuum (<510-5 mbar) with 100% penetration. The electron beam welding will be performed at IUAC. The radial fitting tolerance for beam welding is typically <0.1 mm. Prior to welding; the niobium parts are de-greased and chemically etched to remove the niobium oxide layer. This will be done at IUAC. After EBW, some resonator parts may be radiographed and/or mechanically polished (by Bidder / IUAC). Thermal shocking (300 K to 77 K) followed by helium mass spectrometer leak testing shall be performed as required (by IUAC). The bare niobium resonator will be electropolished and heat treated in vacuum at ~1000 C. All electron beam welding, chemical electropolishing, heat treatment, thermal shocking, RF tuning and helium leak testing will be done by IUAC. SS Outer Jacketing & TIG welding (Bidder’s scope) All stainless steel welds are TIG welds of cryogenic quality, i.e. they should be leak tight (at leak rates <110-9 mbar.l/s) at 4.2 K (~269 ºC). The TIG welding must be performed by flushing both the external and internal surfaces with inert gas. Filler rods of appropriate grade must be used. The entire TIG welding job will be done by the Bidder at his site in the presence and under the supervision of Tender Document IUAC/NIT/13/SSKS/2014-15 Page 8 of 14 IUAC engineers.
