The Tube Envelope and Housing
The Tube Envelope and Housing- The Envelope-The envelope must be strong enough to withstand atmospheric pressure, resistant to the considerable amount of heat produced by the anode and able to transfer this heat away efficiently. Historically, it was…
Components of the X-ray Tube
Components of the X-ray Tube- The Cathode-The cathode assembly normally consists of two parts— (a) an electron source (emitter) and (b) an auxiliary electrode surrounding it. The electron emitter is usually a coiled wire filament 0.2–0.3 mm in…
Electric Supply In X Ray Tube
Electric Supply In X ray Tube- Electrical Circuits- Brief details will be given of the essential electrical components of an X-ray generator. The Transformer-This provides a method of converting high ACs at low potential difference to low ACs at…
Switching and Timing Mechanisms
Switching and Timing Mechanisms- Most Switching and Timing Mechanisms takes place in the primary circuit of the high voltage transformer where, although the currents are high, the voltage is low. Switching in the high voltage secondary circuit is only…
Electrical Safety Features in X-ray tube
Electrical Safety Features- A number of Electrical Safety features of the design of X-ray sets are primarily for safety and should be summarised briefly. The Tube Housing- As already indicated in previous blogs, this provides a totally enclosing…
Spatial Distribution of X-rays
Spatial Distribution of X-rays- When 40 keV electrons strike a thin metal target, the directions in which X-rays are emitted are as shown in (Figure 1 a). Most X-rays are emitted at angles between 45o and 90o to the direction of electron travel. The more…
