1 SCOPE

This Statement of Work (SOW) will be the basis for the procurement of the Beryllium Hemispherical Dome Window Assembly to be used at the Brookhaven Linac Isotope Producer (BLIP) at Brookhaven National Laboratory (BNL) managed by Brookhaven Science Associates (BSA). This document outlines the Contractor’s responsibilities and obligations necessary for completing the requirements as set forth herein.

1.1 Background

To separate the high vacuum upstream side from low vacuum downstream end of the BLIP, a Beryllium (Be) vacuum window is being used. Because of its low mass density, Be is the best choice material for the high flux proton beam used to irradiate materials in BLIP. BLIP has been using Be windows to reduce beam loss for more than two decades. The Be window is attached to an Aluminum housing, with flanges at both ends, through electron-beam welding. Since these windows are used in a high radiation beamline, their reliability is critical to operations and to keep radiation dose received by staff low.

After cleaning, all components shall be handled in accordance with their intended use in an UHV system. They shall be kept free of contamination due to handling and contact with dirt or oil. Any parts that have been contaminated prior to welding shall be cleaned again.

The following guidelines shall be followed to keep the window assembly free from contamination:

1. Welding, inspection, and packaging of the window assembly shall take place in a dedicated clean area.

2. The component parts and assembly shall be kept in clean plastic bags unless they are being inspected or used for fabrication.

3. Clean parts shall only be handled with clean white nylon, powder free latex, or lint free cotton gloves. Clean lab coats and separate elastic-cuffed sleeves shall be worn to prevent contact of the workers’ arms and/or bodies with the clean parts.

4. All tools and inspection gauges which come in contact with the clean component parts shall be cleaned prior to use. When not in use, tools shall be covered and stored to maintain cleanliness. Tools shall not be made of material which can contaminate the clean parts.

5. Work bench surfaces shall be thoroughly cleaned with detergent, rinsed with water, and then wiped with alcohol. The surface shall be hard and non-absorbent (stainless steel, formica etc.).

Wood bench tops or similar materials are not acceptable.

3.2.4.6 Cleanliness

The completed assembly shall be clean and require no further cleaning at BNL. No traces of hydrocarbons, organic or inorganic residues from the fabrication or handling shall be present.

3.2.5.1 Factory Acceptance Testing

The following tests shall be carried out by the Contractor:

1. Dimensional Inspection: Dimensions of the window assembly shall be measured for conformance to the FDR Report. The window thickness must be measure at multiple locations and reported. The Contractor shall produce an inspection report confirming the dimensions and tolerances as per the FDR report. The Contractor shall provide detailed information concerning inspection procedures and equipment to the BSA Technical Representative for written approval.

2. Leak Test: The Contractor shall perform a leak test as per ASTM Specification E 498, “Standards Test Methods for Leaks Using the Mass Spectrometer Leak Detector or Residual Gas Analyzer in the TRACER Probe Mode”, Method A. The pumping must be carried out from convex side of the window such that convex side is in vacuum and concave side is at atmospheric pressure. During leak checking, the entire face of concave side of the window including the weld joint with Aluminum shall be exposed to Helium at 1 atm pressure for minimum 1 hour. This can be done by bagging that area using plastic and tape.

The leak rate must not exceed 1 x 10-10 Atm.cc He/sec for the entire duration of the test.

The leak detector used shall be calibrated at the beginning and ending of each working shift with a standard traceable to the National Institute of Standards and Technology (NIST).

Records shall be kept of the calibration process.

Special care shall be taken not to contaminate the window assembly and only oil free vacuum pumps shall be used to eliminate back streaming roughing oil. Viton O-rings may be used as temporary seals for leak detection. No lubricants or greases of any kind are to be used on the O-ring seals.

3. Bake and Leak Rate Tests: After leak checking, the Contractor shall bake the assembly for

8 hours minimum at 1500C excluding ramp up and ramp down time at the rate 500C/hr max. The assembly must remain leak tight during and after baking. After the bakeout is finished and the assembly is at room temperature, it shall be vented to atmospheric pressure with dry, high purity (99.9%) nitrogen bottle gas or from an evaporated liquid nitrogen source. Once vented, the assembly shall be stored in a clean dry sealable plastic bag to avoid any exposure to water, humidity, or debris. If the contractor doesn’t have the capability to do bakeout test, BSA can do it and the contractor must agree to honor BSA’s finding.

3.2.5.2 Acceptance Testing at BNL

Upon receipt, BSA reserves the right to perform acceptance testing to include dimension check, Be dust check, a leak test, outgassing test and bake test. Beryllium dust shall not exceed 0.2µg/100cm2. The leak test will be performed at room temperature, during and after bake out. A bake test to be carried out at 1500C for 72 hours excluding ramp up and ramp down time at the rate 500C/hr max. A limited dimension check will also be carried out at BNL.

Conformance to the outgassing requirements of section 3.2.2.3 shall be tested using conventional all-metal UHV practices. During initial pump down and after bake out, a residual gas analyzer
