This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. This procurement is being conducted under the Simplified Acquisition Procedures(SAP)FAR Subpart 13.5 -- Test Program for Certain Commercial Items. Request for Quotation (RFQ)5-09742 is for the acquisition of 260 photomultiplier tubes for the Gamma-ray Large Area Space Telescope (GLAST) Anticoincidence Detector (ACD). Photomultiplier tubes are the sensor of choice for the low light levels coming from the plastic scintillators. The high efficiency required for anticoincidence demands a photomultiplier tube with capability of detecting single photoelectrons. The GLAST ACD requires 260 small photomultiplier tubes. All tubes must be sufficiently reliable and tested for space flight use. Deliverables This procurement is for Photomultiplier Tubes that meet the Photomultiplier Tube (PMT) Requirements detailed below, to be delivered according to the schedule shown below. All test data shall be delivered with each PMT. Failure reports shall be submitted on any PMT's that fail to meet the Performance Requirements after testing (see below). Photomultiplier Tube Requirements Physical Requirements for the Photomultiplier Tubes 1. Head-on type cylindrical tube 2. Bi-alkali cathode 3. Outside diameter less than or equal to 15.2 mm 4. Length less than or equal to 80 mm, not including leads 5. Flying lead connections at least 40 mm long, with ends tin-lead solderable to within 10 mm from the glass stem 6. Minimum cathode diameter 9 mm 7. As delivered, all PMT's shall be soldered to a temporary base to enable initial electrical testing. Performance Requirements for the Photomultiplier Tubes 1. Minimum current gain at maximum high voltage shall be 2,000,000. 2. Cathode luminous sensitivity shall be greater than 90 microamps/lumen. 3. Anode dark current shall be less than 10 nanoamps at a gain of 500,000 and a temperature of 20 C. 4. High voltage required at a gain of 2,000,000 shall not exceed 1500 V. 5. Projected gain degradation shall be less than 30% (84% probability) after 50,000 hours of operation at a mean anode current of 30 nanoamps. The projection shall be based on accelerated life tests at higher currents with tubes of the same design. Proposals shall detail how such test have been conducted. The PMT's to be delivered under this solicitation shall not undergo such accelerated life tests. Environmental Requirements to be Met by the Photomultiplier Tubes 1. Temperature range: The PMT's shall operate within specification over a range -20 C to +45 C. 2. Temperature rate (dT/dt): the PMT's shall operate within specification while experiencing temperature change (within the above range) at a rate of (flight) 5 C/hr; and (test) 20 C/hr. 3. Temporal stability: At a constant temperature of 20 C, gain variation shall be less than 2% per 10 days. 4. Vibration: The PMT's shall operate within specification, and with parameter changes not exceeding the values shown below, after experiencing the following Qualification Level vibration environment in accordance with http://arioch.gsfc.nasa.gov/302/gevs-se/sec2-4.pdf . 5. Shock: The PMT's shall operate within specification, and with parameter changes not exceeding the values shown below, after experiencing Delta2 qualification level shock testing in accordance with http://arioch.gsfc.nasa.gov/302/gevs-se/sec2-4.pdf . 6. Radiation: the units shall operate, within specification and with parameter changes not exceeding the values shown below, after a total dose of 10 kRad. Limits on Performance Changes Due to Vibration, Shock, or Radiation Cathode luminous sensitivity shall not change by more than 10%; Current gain shall not change by more than 25%; Anode dark current (at a temperature of 20 C) shall not increase by more than 100%. (All three of the parameters listed above must be within specification both before and after the vibration, shock, or radiation exposure.) Quality Requirements to be Met by the Photomultiplier Tubes 1. The Photomultiplier Tube Quality Plan shall be consistent with the following: ISO-9001; GSFC 433-MAR-0001, "The Mission Assurance Requirements for the Large Area Telescope;" LAT Performance Assurance Implementation Plan (SLAC LAT-MD-00039); "Quality Plan for the Anticoincidence Detector" (GSFC ACD-QA-8001). 2. The PMT's must be space flight qualifiable according to 433-SPEC-0001 (GLAST, Mission System Specification). Delivery Schedule 1. Basic Contract -- Ten (10) Qualification Unit PMT's shall be delivered within 15 weeks after contract award; 2.

Each tube shall be delivered with its performance data (offeror's standard data package, measured both before and after the 12-hour burn-in). Level 2 Intermediate testing: Following the testing described in Option 1, each PMT shall be vibration tested: Engineering Units -- at Workmanship Level, 3db below Flight Acceptance Level (see below) (Note that the 40 Engineering Unit PMT's will experience Qualification Level vibration during testing of the LAT engineering unit); Flight Units -- at Flight Acceptance Level in accordance with http://arioch.gsfc.nasa.gov/302/gevs-se/sec2-4.pdf For Level 2, electrical performance parameters (offeror's standard data package, plus Items 1-4 from "Performance Requirements for the Photomultiplier Tubes" above if not included in the standard package) shall be measured before and after the vibration test.
