66 -- POST ACCELERATION KIT AS ADD-ON TO IMS-4F: ION MASS SPECTROMETER SOL 40SBNB060021 DUE 012500 POC Kathy Fain, Contract Specialist (301) 975-6337, or Anita Tolliver Contracting Officer (301) 975-6308; FAX (301)963-7732 WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. The National Institute of Standards and Technology (NIST) intends to enter into a sole source purchase order with Cameca Instruments Inc. of 204 Spring Hill Road, Trumball, CT 06611-1356 for a Post Acceleration Kit as an add-on to the already installed Cameca IMS-4F Ion Microscope, under the authority of Federal Acquisition Regulation (FAR) Subpart 13.106-1(b) Soliciting from a Single Source. The equipment shall be sent FOB Destination NIST Gaithersburg, MD. Required delivery time is 5 months from the date of award. NIST does not require installation. Cameca Instruments Inc. is the designer and manufacturer of the Ion Mass Spectrometry equipment-the IMS-4F-currently in use at NIST. The add-on of the Post Acceleration Kit to the current Ion Mass Spectrometry equipment (Cameca IMS-4F Ion Microscope) will prove beneficial by boosting the post acceleration to the secondary ions reaching the first dynode of the electron multiplier from -10kV to +8kV. This energy gain significantly improves the ion to electron conversion efficiency of the EM fist dynode when dealing with heavy species or running the mass spectrometer at low secondary extraction voltage. (<3kV). It will eliminate the loss of the electron multiplier performance and will also minimize the mass dependence of the electron multiplier efficiency. The Cameca Post Acceleration Kit is the only such item that is compatible with the Ion Mass Spectrometor 4F currently installed at NIST. Therefore, Cameca Instruments Inc. is the only source that can fulfill this requirement. The components of the Post Acceleration Kit shall include: electronic chassis (133mm height); mechanical parts for electrical isolation of the electron multiplier; electron multiplier ETP133H to replace the existing Balzers model; new design of Electron multiplier preamplifier with fixed dead time. The system shall have post acceleration voltage adjustable from -10 to +8kV. The system shall have EM yield >80% for mass species<200 amu at 1kV secondary extraction voltage. The system shall have computer controlled EM parameters. The system shall have pulse height distribution measurement capability. The Government anticipates the award of a firm-fixed price purchase order. A determination by the Government not to compete this proposed order based upon responses to this notice is solely within the discretion of the Government. Written responses to this synopsis shall contain sufficient documentation to establish a bonafide capability to fulfill this requirement. A solicitation is not available. If you have any questions regarding this announcement, please contact Kathy Fain at the telephone number identified above. Posted 01/14/00 (W-SN416283). (0014)
