Test results for each cylinder and end cap pair All items shall be in accordance with the following statement of work/specifications. NOTE: Sketches identified in "A. Description" may be obtained by submitting an e-mail or faxed request to Glynda H. Meeks, e-mail address/fax number shown below. I. GENERAL REQUIREMENTS A. DESCRIPTION Two vacuum chamber extension spools will be procured for use at the NASA/MSFC X-ray Calibration Facility (XRCF). These spools shall consist of two stainless steel horizontal cylindrical sections and four endcaps. The spools shall interface with each other and an existing vacuum chamber at the XRCF to create one long vacuum chamber. They shall also be able to stand alone (by using the four endcaps) to create two smaller vacuum chambers should the need arise. The overall dimensions of each individual cylinder shall be 48" diameter x 96" long. The integral support stand shall be of a low profile design so that the cylinder centerline is approximately 31.5" above the floor. Each cylinder's (and end cap's) interior surface shall be 120 grit polished (or bead blasted if an acceptable vacuum-compatible surface finish is achieved). The exterior surfaces shall be of an attractive surface finish. O-ring grooves and sealing surfaces shall be 32 microinch rms finish or better. The cylinders and end caps shall be designed to withstand the vacuum loading. Stiffening rings/supports shall be added as necessary. Each cylinder shall have six penetrations. These penetrations are to be 8" tube half-nipples. The ASA-type flange OD is 11" and should be nominally 4" from cylinder wall and should have an o-ring groove. The orientation and location of each penetration is called out on the attached sketch. Blanks (blinds), o-rings, and bolts shall be provided for each penetration. Two cylinder end caps shall have a centerline-mounted 20" ASA flange type nozzle (27 = " OD) with a 20 =" ID o-ring groove. The other two end caps shall have no penetrations. The end caps shall be easy to install and remove. Each end cap shall have its own wheeled carriage and be capable of being lifted from a single point above the center of gravity. The carriages for the end caps with the 20" nozzle shall be capable of carrying the additional load of a 20" stainless steel gate valve and a 20" cryopump (1100 lbs total). Each end cap carriage shall include an elevation adjustment and a pitch angle adjustment for the end cap (a three point hitch type design will suffice). B. DIMENSIONS The dimensions specified in this statement of work are approximate. Actual dimensions shall be provided by the contractor for review prior to fabrication. C. INTERFACES The two cylinders shall interface with each other end to end. The cylinders shall also interface with the existing vacuum chamber at the XRCF. The description of the sealing surface and o-ring groove on the existing vacuum chamber are provided in the sketch. The method of joining cylinder-to-cylinder and cylinder-to-end cap shall be interchangeable and easily aligned and fastened. D. FABRICATION The fabrication techniques employed shall be consistent with standard practices of fabrication for vacuum service. E. CLEANINESS The cylinders and end caps shall be detergent washed and alcohol dried following polishing (blasting) and shall be maintained in this clean condition during shipment. Shipping with all penetration covers and end caps bolted in place should suffice. F. TESTING Each cylinder and end cap pair shall be helium mass spectrometer leak tested and shown to have a total leak rate of less than 2 x 10-8 atm-cc/sec with a sensitivity of 1 x 10-9 atm-cc/sec. Test results shall be submitted with the delivery of the cylinders. II. DESIGN SUBMITTAL/REVIEW/APPROVAL A set of design drawings with detailed proposal shall be submitted to the government for review/approval prior to fabrication. III. SCHEDULE Design shall be completed for review within 45 days after award. Delivery shall be 165 days after award. The provisions and clauses in the RFQ are those in effect through FAC 97-14.
