PRINCIPAL TECHNICAL DATA

Notes:

1. Instability of power supplies of voltages and the filament current must not exceed the significances indicated in the present table.
2. Nom-nominal significance of a parameter indicated in the column "Significances of parameters actual".
3. The filament voltage covers 1.7-2.3V.
4. The stabilization of the filament voltage is allowed in the filament power supply (instability of the filament voltage is not worse than indicated for the filament current).

OPERATION INSTRUCTIONS

All voltage are given in respect to the cathode.
During original installation the TWT, the voltages of anodes and the filament current should be set equal to the nominal values, indicated in the column " Significances of parameters actual" of the section I of the present certificate. The slow-wave structure voltage is set in the limits indicated in the column " Significances of parameters allowable operating" for the minimum noise factor or maximum value of the power gain.
The nominal electrical behaviour is chosen by the producer for the given TWT in the following limits:

During installation of the TWT in apparatus and in the operating process in every 200 h of an operation, in order to get the minimum value of the noise factor at allowable values of the power gain and total starting time in case of need it is permitted to change the electrode voltages in the indicated ranges and the filament current in the limits nom +4%/-2%.
The TWT has the natural cooling.
It is permitted the arbitrary position of ferromagnetic materials at the distance more than 50 mm from the TWT.
It is permitted to locate the ferromagnetic materials at the distance not less than 10 mm from the TWT when one of axes symmetry coincides and two rest axes are parallel.
It is permitted the relative position of the TWTs at the distance not less than 100 mm when fixing the TWT in one plane and also when fixing the TWT in different planes, at that one of axes of the TWT must coincide with the corresponding axis of another TWT and two others are parallel in pairs.

SWITCH ON PROCEDURE

Without connecting the supply connector to the TWT, switch on the power supply and set the voltages of anodes, slow-wave structure, collector to the nominal values and the filament voltage equals to 2 V.
Switch off the power supply.
Connect the power supply to the TWT.
Switch on the filament voltage, adjust the filament current to the nominal value.
In 1 min after switching on of the filament voltage switch on the voltages of the rest of electrodes (simultaneously).

Notes:

1. By repeated switching on of the adjusted TWT the adjustment of voltages is not required as a rule.
2. It is permitted to switch on supplying voltages at their earlier set values simultaneously.

SWITCH OFF PROCEDURE

Switch off the voltages of anodes, the slow-wave structure and the collector simultaneously.
Switch off the filament voltage.

Note: It is permitted to switch off all supplying voltages simultaneously.

It is not permitted to switch off the filament voltage when the high voltages are switched on.
