The Standard Industrial Classification Code is 3826, and the business size standard is 500 employees. A. Background: The In Vivo NMR Research Center currently has a 4.7 Tesla 40 cm imaging intrument that was originally purchased from General Electric NMR instruments. This instrument was upgraded in February 1997 to use a Varian Inova control console configured for imaging, using a Sun Ultra workstation as the user interface, using the original Oxford magnet model 200/400 horizontal bore, system 29588, and magnet 27537. The present GE/Bruker Acustar shielded gradients are driven by a set of Crown Techron 8606 amplifiers. The room temperature shim supply is an Oxford 14-channel modular supply. The gradient cooling is provided by a Neslab System II water-to-water heat exchanger using PD1 pumps supplying recirculating water at 80 psi, 1.5 liter/minute at 45 degrees Fahrenheit. B. Basic Requirement:1.

Shielding: Integral RF shielding with hinged end-cap doors and in-line filters for current and sensor lines to provide at least 80 db of shielding from external RF signals for frequencies from 25 Mhz to 200 MHz. Risetime: Less than 300 usec 1% to 99% rated gradient strength using proposed gradient amplifiers. 2.

Duty cycle: at least 20% of the maximum rated gradient continuous on all axes simultaneously, and 25% of maximum gradient on any one axis continuous. Built-in Room Temperature Shims: Z0, Z2, Z3, Z4, ZX, ZY, R2, XY, Z2X, Z2Y, ZR2, ZXY; The related supporting information must include the strength of each component of shim at 2 amperes shim current. Temperature sensors: at least four, placed at potential hot-spots of gradients, embedded sensors, to interface with Gradient Monitor Electronics below. 3.

Settings for maximum gradient temperature, peak currents, and duty cycles must be settable for each of several gradient sets, in software supplied by vendor. Temperature monitor circuits should be compatible with the existing government-owned gradient sets with imbedded copper-constantan thermocouples. 4. Gradient Amplifier Set: Provide a gradient amplifier set to meet the following requirements: To provide voltage (at least 100 volts) and current (at least 100 amperes) required for each of the gradient sets offered to meet their performance specification. Eddy Current Electronics: To provide compensation for at least three (3) components of eddy current gradients in each of X, Y, Z, BO, and cross-terms XY, YX, ZX, XZ, YZ, ZY and ZZ2. It must be programmable in software provided by the vendor. Inputs: a) balanced analog drive, 2 vpp to give maximum output current; b) balanced input for shim current (+ or -- 10 vdc input to give small dc offset in gradient current, with adjustable gain settings) c) a 16-bit digital drive would be desirable Adaptability -- to be easily adaptable for various gradient coil sets, including three (3) existing smaller (120mm, 65mm and 35 mm I.D.) government-owned sets, to include supplying compatible cable connectors for current- and temperature-sensing cables, to be attached to the existing sets. Duty Cycle: Specify the ramping duty cycle, including (1) the percentage of time that the amplifier set can run a triangle gradient at rated risetime of gradients and rated current, and (2) the current amplitude the amplifier set can continuously run a triangle gradient at rated minimum risetime.
