- Description
- The purpose of this amendment is to provide answers to questions received from potential offerors and to provide additional information to be used as a guide with the specifications: 1. Q: Regarding point 2.3.5.2 for the integration of your electron source LEG 200 we would need some more information on the scan unit. Do you know if it has an analog external input? It would be very helpful if you could provide us with a copy of the manual. A: The scan unit does not have an analog external input that I can tell. Although, the little bit of documentation that I have indicates that it could be computer controlled. The scan unit has 4 cables that come out (x1, x2, y1, y2) to the LEG 200 gun which controls the raster and has 2 cables that come in from the secondary electron detector (a BNC video in and a strange 9 pin connector that is also labeled video input). The x and y output voltages start at 100 VDC and decrease to nearly 0 as the magnification is increased. I did not put the outputs to an oscilliscope to determine what frequency is being used to sweep the beam. The rate at which the x (1 & 2) and y (1&2) voltages are switched. This causes a rastering of the electron beam in order to obtain a TV image. Have you ever looked at the SETTINGS of your computer monitor? The frequency can be 50 Hz, 68 Hz, 72 Hz, or nearly any value. For the scan unit to form a secondary electron detection (the TV image), the electron beam must be rastered by switching voltages at a frequency. I do not know the frequency the scan unit is using. 2. Q: Point 2.6.2 I understand that we should also offer an additional In-situ ultra-high vacuum transfer system consisting of a track and trolley system and wobblestick. We thought that you would want to use your existing transfer system. Please clarify if we should offer this. A: We do not need a trolley system. We already have a cart and trolley system, which must be used. Any new chamber must have a port and proper dimensions to allow the trolley system to bring samples into the XPS system from the connecting Preparation Chamber. The port should be an 8" (inches) CF flange, as that is what is currently used. It is conceivable that a 6" CF flange may work as the cart is only 3.5" wide and 3" tall. We do not need a wobble stick either, as we have one which can be used. The purpose of section 2.6.2 was to provide information on how samples are to be brought into the XPS system by us. 3. Q: Do you accept payment terms that are: 65% prepay (on order) 30% on delivery 5% on final acceptance A: Payment arrangements can be in accordance with FAR Part 12. 4. Q: Is there a given budget on the bid? A: No. 5. Q: Would it be possible for the end user to supply details about the existing chamber pumping and any pumping associated with individual instruments? NOTE: THIS NOTICE WAS NOT POSTED TO FEDBIZOPPS ON THE DATE INDICATED IN THE NOTICE ITSELF (23-APR-2007); HOWEVER, IT DID APPEAR IN THE FEDBIZOPPS FTP FEED ON THIS DATE. PLEASE CONTACT fbo.support@gsa.gov REGARDING THIS ISSUE.
