1 NATIONAL RADIO ASTRONOMY OBSERVATORY Green Bank, West Virginia ELECTRONICS DIVISION INTERNAL REPORT NO. 2 THE ELECTRON BEAM PARAMETRIC AMPLIFIER By DEWEY ROSS and ROBERT HAAS SEPTEMBER 1962 NUMBER OF COPIES: 15 Rerun 11/10/66: 50 copies
2 THE ELECTRON BEAM PARAMETRIC AMPLIFIER The information contained herein covers the practical application of the Adler tube since it was returned from Zenith in March where the following modifications were made* The input and output connectors have a "c" clamp to keep the inner conduc tor from moving the coupling loop. Micrometers were added to give an indication of mechanical alignment of the input and output couplers. End bell clamping as sembly was modified to allow more precise positioning of the R. F. capsule in the magnet. Both tubes were checked; tube 333 was erratic and had to be reconditioned. The DC block and pump balun were modified to operate above ground, and a change was made in the power supply unit here and this was noted on the schematic. Noise temperatures measured higher than those specified by Zenith. However, their measurements were made with an automatic noise figure indicator while the ones measured here by the Y-factor method, using an Argon tube and hot-cold source. Stability tests with tube 334-R noise temperature of K and 40 db gain show approximately. 3 TC peak-to-peak noise with 15 second integration time. Changes in room temperature are quite evident on the output record. By the proc ess of elimination, the quadrapole voltage and magnet seem quite sensitive to such changes. Pump frequency and output seem to be constant with temperature change but both are quite critical to the proper alignment for obtaining best noise tempera ture of the EBP A. The magnet supply uses two Kepco power supplies in series. This modification was made by D. Durand and has good stability once warm-up has been obtained. Variation of Adler Tube Noise Temperature With Operating Parameters The results of measurements made on the noise temperatures of two Adler tubes between June 21 and September 15, 1962 are shown on the accompanying graphs. In addition, to the plotted parameters, the interception current was also monitored. It was found that lowest noise temperatures and best stability occurred
3 -2 - simultaneously with low interception current. The interception current is monitored at the cuccia couplers and is used as an indication of proper beam position. Any mismatch or improper voltages and currents change the beam position and therefore induces a current into the plates of the couplers. There fore, in beginning measurements after installing the tube, the best procedure is to adjust the mechanical adjustments for minimum interception current and the electrical adjustments as per the manufacturer's specifications. This will bring the noise temperature within a range readable on the Automatic Noise Figure Indicator. Once this is achieved, the system can be adjusted for lowest noise temperature directly. It was found that it is possible to get very close to the proper mechanical adjustment, local oscillator frequency, and mixer current on the first try. Following this, lowesti noise temperature is achieved by cyclic adjustment of the other electrical parameters with occasional modification of the above-mentioned three. Once a low noise temperature was achieved, it remained constant over long periods of time (days). In fact, the distrubing factors were usually external to the tube, such as equipment failures or changes in the measure ment program. As can be seen from the attached graphs, the noise temperature is extremely sensitive to changes in the tube voltages, currents, and frequencies, and the Quad rapole voltage being the most critical and Electrode B Voltage being the least critical. The critical parameters are usually adjusted very close to the brink of noise temperature degeneration. If they are set too close to the drop off point, slight instabilities, in power supply or room temperature for instance, will cause a degradation in noise temperature. The gain vs. pump power and noise temperature vs. pump power measure ments show that the Rhode and Swartz SLRD is not as stable as the FXR pump. However, one should consider the fact that during the two above-mentioned mea surements the pump had to be turned off and on, and therefore the stability would not be as good. The two tubes showed similar characteristics as far as sensitivity to parameter change, but tube 233-R gave a much lower noise temperature (100 ) than did tube 234-R (140 ).

(Noise temperature is measured with Hot-Cold Noise Source.)
