Description

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 approximately 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) Performance Requirements detailed below to be delivered according to the schedule shown below. All required test data shall be delivered with each PMT. Photomultiplier Tube Requirements Physical Requirements for the Photomultiplier Tubes 1. Head-on type tube 2. Bi-alkali cathode 3. Diameter less than or equal to 15.2 mm 4. Length less than or equal to 80 mm, not including leads 5. Solderable flying lead connections Performance Requirements for the Photomultiplier Tubes 1. Minimum current gain at maximum high voltage shall be 2 x 106. 2. Cathode sensitivity shall be greater than 90 microA/lumen. 3. Temporal stability: Gain variation shall be less than 0.2% per day. 4. Anode dark current shall be less than 5 nA at nominal high voltage. 5. Projected gain degradation shall be less than 30% (1 sigma, i.e., 84% probability) after 50,000 hours of operation at a mean anode current of 30 nA. The projection shall be based on accelerated life tests at higher currents with tubes of the same design. Environmental Requirements to be Met by the Photomultiplier Tube 1. Vibration and shock: the Engineering and Flight PMT's shall operate within specification, and with less than 10% parameter change, after experiencing a Delta2 launch environment in accordance with http://arioch.gsfc.nasa.gov/302/gevs-se/sec2-4.pdf , page 20. 2. Temperature range: the units shall operate within specification over a range -200C to +450C. 3. Temperature rate (dT/dt): the units shall operate within specification while experiencing temperature change at a rate of (flight) 50C/hr; and (test) 200C/hr. 4. Radiation: the units shall operate, within specification and with less than 10% parameter change, over a total dose of 10 kRad. Quality, Safety, and Mission Assurance Requirements to be Met by the Photomultiplier Tube 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) and MN000928D1 (LAT Mechanical Performance Specifications). The PMT's shall meet the vibration and shock requirements of MN000928D1 (LAT Mechanical Performance Specifications). Hard Copies of the documents referenced above and listed below will be available in the Procurement Library. To obtain a copy contact Veronica Stubbs at 301-286-8386.

Basic Contract -- Ten (10) Qualification Unit PMT's shall be delivered on or before January 3, 2002; 2. Option 1 -- Forty (40) Engineering Unit PMT's shall be delivered on or before June 1, 2002; 3. Option 2 -- Two hundred ten (210) Flight Unit PMT's shall be delivered on or before March 1, 2003. Delivery shall be FOB Destination to the Goddard Space Flight Center Greenbelt, MD 20771. Testing Offerors shall price the Engineering and Flight PMT's with three (3)optional levels of testing to be performed by the offeror: Level 1 -- Offeror's standard electrical performance testing. Each PMT shall be visually inspected. Each tube shall be operated at 30 microamps anode current for at least 12 hours. 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. In addition to the testing described in Option 1, each PMT shall be vibration tested: Engineering Units -- at "workmanship" level in accordance with http://arioch.gsfc.nasa.gov/302/gevs-se/sec2-4.pdf , page 21) (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 , page 20). For Level 2, electrical performance parameters (as shown in the Performance Requirements) shall be measured before and after the vibration test. Failure reports on any Qualification Unit PMT's that fail to meet the Performance Requirements after vibration testing shall be submitted (see below). In the event that any Engineering or Flight PMT fails to meet the Performance Requirements after the vibration test, that failure shall be reported to the Technical Officer. Within two (2) working days, the failed PMT shall undergo failure analysis, the results of which shall be delivered at a mutually agreed upon time based on the type of failure. Level 3 -- Extended testing. In addition to the testing described in Levels 1 and 2, each PMT shall be operated at 30 microamps anode current for 100 hours (burn-in), with the Current Amplification measured initially and after 24, 48 and 100 hours of operation. The full performance parameters (offeror's standard tests, plus items 1, 2, and 4 from the Performance Requirements) shall be measured before and after the 100 hour test; the post-burn-in parameters shall not differ by more than 10% from the pre-burn-in values.
